    Phase II of photosynthesis uses the products of Phase 1 as inputs excepting oxygen, which bubbles into the atmosphere. Phase 2 is known as the Calvin cycle, after Berkeley After providing an overview of photosynthesis, these animations zoom inside the cells of a leaf and into a chloroplast to The process is also found in single-cell organisms such as cyanobacteria that do not have Photosynthesis occurs within the chloroplast. A cellular organelle found in plants and some algae. Photosynthetic reactions also happen within Problem 6: Events during light reactions. What three events occur during the light reactions of photosynthesis? Photosynthesis is an endothermic reaction. This means it cannot occur without energy from the Sun. The light required is absorbed by a green pigment called chlorophyll in the leaves. Photosynthesis involves several different chemical reactions, but these can be summarised in two main stages.

  • 5.1: Overview Of Photosynthesis

    A digital version of the Year 7 C1 3. Photosynthesis is considered to be an "endothermic reaction" because it absorbs the sun's energy to enable the reaction to happen. Like most of the endothermic reactions, the plants do not absorb heat but they absorb sun's photothermal energy to perform 'photosynthesis' in order to produce starch.

    Chapter 5: Introduction to Photosynthesis 5. It is easy to think of light as something that exists and allows living organisms, such as humans, to see, but light is a form of energy. Like all energy, light can travel, change form, and be harnessed to do work. In the case of photosynthesis, light energy is transformed into chemical energy, which autotrophs use to build carbohydrate molecules. However, autotrophs only use a specific component of sunlight Figure 5.

    Figure 5. Fish and Wildlife Service Concept in Action Visit this site and click through the animation to view the process of photosynthesis within a leaf. What Is Light Energy? The sun emits an enormous amount of electromagnetic radiation solar energy. Scientists can determine the amount of energy of a wave by measuring its wavelength, the distance between two consecutive, similar points in a series of waves, such as from crest to crest or trough to trough Figure 5.

  • 5.2: The Light-Dependent Reactions Of Photosynthesis

    Visible light constitutes only one of many types of electromagnetic radiation emitted from the sun. The electromagnetic spectrum is the range of all possible wavelengths of radiation Figure 5. Each wavelength corresponds to a different amount of energy carried. This radiation exists in different wavelengths, each of which has its own characteristic energy. Visible light is one type of energy emitted from the sun. Each type of electromagnetic radiation has a characteristic range of wavelengths.

    The longer the wavelength or the more stretched out it appears , the less energy is carried. Short, tight waves carry the most energy. This may seem illogical, but think of it in terms of a piece of moving rope. It takes little effort by a person to move a rope in long, wide waves. To make a rope move in short, tight waves, a person would need to apply significantly more energy. The sun emits a broad range of electromagnetic radiation, including X-rays and ultraviolet UV rays. The higher-energy waves are dangerous to living things; for example, X-rays and UV rays can be harmful to humans. Absorption of Light Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye. The visible light portion of the electromagnetic spectrum is perceived by the human eye as a rainbow of colors, with violet and blue having shorter wavelengths and, therefore, higher energy.

    At the other end of the spectrum toward red, the wavelengths are longer and have lower energy. Understanding Pigments Different kinds of pigments exist, and each absorbs only certain wavelengths colors of visible light. Pigments reflect the color of the wavelengths that they cannot absorb. All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum blue and red , but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll b which absorbs blue and red-orange light and the carotenoids. Each type of pigment can be identified by the specific pattern of wavelengths it absorbs from visible light, which is its absorption spectrum. Many photosynthetic organisms have a mixture of pigments; between them, the organism can absorb energy from a wider range of visible-light wavelengths.

    Not all photosynthetic organisms have full access to sunlight. Some organisms grow underwater where light intensity decreases with depth, and certain wavelengths are absorbed by the water. Other organisms grow in competition for light. Plants on the rainforest floor must be able to absorb any bit of light that comes through, because the taller trees block most of the sunlight Figure 5. Each pigment can absorb different wavelengths of light, which allows the plant to absorb any light that passes through the taller trees. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.

  • Photosynthesis - Planning Sheet 8.3

    Photosystems exist in the membranes of thylakoids. A photon of light energy travels until it reaches a molecule of chlorophyll. To replace the electron in the chlorophyll, a molecule of water is split. Technically, each breaking of a water molecule releases a pair of electrons, and therefore can replace two donated electrons. The energy culminates in a molecule of chlorophyll found in the reaction center. A molecule of water splits to release an electron, which is needed to replace the one donated. Oxygen and hydrogen ions are also formed from the splitting of water. The replacing of the electron enables chlorophyll to respond to another photon.

  • Calvin Cycle Key

    The oxygen molecules produced as byproducts find their way to the surrounding environment. The hydrogen ions play critical roles in the remainder of the light-dependent reactions. Keep in mind that the purpose of the light-dependent reactions is to convert solar energy into chemical carriers that will be used in the Calvin cycle. In eukaryotes and some prokaryotes, two photosystems exist. The first is called photosystem II, which was named for the order of its discovery rather than for the order of the function. After the photon hits, photosystem II transfers the free electron to the first in a series of proteins inside the thylakoid membrane called the electron transport chain. As the electron passes along these proteins, energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space.

  • Process Of Photosynthesis

    This is quite analogous to the process that occurs in the mitochondrion in which an electron transport chain pumps hydrogen ions from the mitochondrial stroma across the inner membrane and into the intermembrane space, creating an electrochemical gradient. After the energy is used, the electron is accepted by a pigment molecule in the next photosystem, which is called photosystem I Figure 5. This electron transport system uses the energy from the electron to pump hydrogen ions into the interior of the thylakoid.

  • Where Do The Light Reactions Of Photosynthesis Take Place Quizlet

    A pigment molecule in photosystem I accepts the electron. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. Recall that NADH was a similar molecule that carried energy in the mitochondrion from the citric acid cycle to the electron transport chain. This potential energy is harvested and stored as chemical energy in ATP through chemiosmosis, the movement of hydrogen ions down their electrochemical gradient through the transmembrane enzyme ATP synthase, just as in the mitochondrion. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase.

  • Photosynthesis Making Energy

    The energy generated by the hydrogen ion stream allows ATP synthase to attach a third phosphate to ADP, which forms a molecule of ATP in a process called photophosphorylation. The flow of hydrogen ions through ATP synthase is called chemiosmosis, because the ions move from an area of high to low concentration through a semi-permeable structure. As the electron from the electron transport chain arrives at photosystem I, it is re-energized with another photon captured by chlorophyll.

    Now that the solar energy is stored in energy carriers, it can be used to make a sugar molecule. Section Summary In the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. The most common and abundant pigment is chlorophyll a. A photon strikes photosystem II to initiate photosynthesis. Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space.

  • 8.3 The Process Of Photosynthesis

    This forms an electrochemical gradient. The ions flow through ATP synthase from the thylakoid space into the stroma in a process called chemiosmosis to form molecules of ATP, which are used for the formation of sugar molecules in the second stage of photosynthesis. Photosystem I absorbs a second photon, which results in the formation of an NADPH molecule, another energy carrier for the Calvin cycle reactions.

    Energy produced by the electron transport chain is used to pump hydrogen ions from the stroma to the inside of the thylakoid. Put the following events of the light-dependent reactions in the order in which they occur: photosystem I, photosystem II, making NADPH, and pumping hydrogen ions into the inside of the thylakoid. Photosystem II Light shining on pigments energizes electrons that come from water. Photosystem I: electrons are reenergized with more light.
