Description This multipart animation series explores the process of photosynthesis and the structures that carry it out. Photosynthesis converts light energy from the sun into chemical energy stored in organic molecules, which are used to build the cells of many producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, these animations zoom inside the cells of a leaf and into a chloroplast to see where and how the reactions of photosynthesis happen. The animations detail both the light reactions and the Calvin cycle, focusing on the flow of energy and the cycling of matter. This animation series contains seven parts, which can be watched individually or in sequence. The first three parts are appropriate for middle school through college-level students. The remaining parts are appropriate for high school through college-level students; Parts 5 and 6 are recommended for more advanced students.

The Light-Dependent Reactions – Principles Of Biology
New York: W. Freeman ; Search term Section In plants, photosynthesis occurs in chloroplasts, large organelles found mainly in leaf cells. The principal end products are two carbohydrates that are polymers of hexose six-carbon sugars: the disaccharide sucrose see Figure and leaf starch , a large, insoluble glucose polymer Figure Leaf starch is synthesized and stored in the chloroplast. Sucrose is synthesized in the cytosol from three-carbon precursors generated in the chloroplast and is transported from the leaf to other parts of the plant. Nonphotosynthetic nongreen plant tissues like roots and seeds metabolize sucrose for energy by the pathways described in the previous sections. Photosynthesis in plants, as well as in eukaryotic single-celled algae and in several photosynthetic prokaryotes the cyanobacteria and prochlorophytes , also generates oxygen.

The overall reaction of oxygen-generating photosynthesis, is the reverse of the overall reaction by which carbohydrates are oxidized to CO2 and H2O. Figure Structure of starch. This large glucose polymer and the disaccharide sucrose see Figure are the principal end products of photosynthesis. Both are built of six-carbon sugars. Our emphasis is on photosynthesis in plant chloroplasts, but we also discuss a simpler photosynthetic process that occurs in green and purple bacteria.

Section 8 3 The Reactions Of Photosynthesis Answers
Although photosynthesis in these bacteria does not generate oxygen, detailed analysis of their photosynthetic systems has provided insights about the first stages in oxygen-generating photosynthesis — how light energy is converted to a separation of negative and positive charges across the thylakoid membrane , with the simultaneous generation of a strong oxidant and a strong reductant. In this section, we provide an overview of the stages in photosynthesis and introduce the main components, including the chlorophylls , the principal lightabsorbing pigments.

Ch. 8 Photosynthesis
Photosynthesis Occurs on Thylakoid Membranes Chloroplasts are bounded by two membranes, which do not contain chlorophyll and do not participate directly in photosynthesis Figure Of these two membranes, the outer one, like the outer mitochondrial membrane , is permeable to metabolites of small molecular weight; it contains proteins that form very large aqueous channels. The inner membrane, conversely, is the permeability barrier of the chloroplast ; it contains transporters that regulate the movement of metabolites into and out of the organelle. Figure The structure of a leaf and chloroplast. Unlike mitochondria , chloroplasts contain a third membrane — the thylakoid membrane — that is the site of photosynthesis. In each chloroplast , the thylakoid membrane is believed to constitute a single, interconnected sheet that forms numerous small flattened vesicles, the thylakoids , which commonly are arranged in stacks termed grana see Figure The spaces within all the thylakoids constitute a single continuous compartment, the thylakoid lumen.

Photosynthesis Guided Notes
The thylakoid membrane contains a number of integral membrane proteins to which are bound several important prosthetic groups and light-absorbing pigments, most notably chlorophyll. Carbohydrate synthesis occurs in the stroma, the soluble phase between the thylakoid membrane and the inner membrane. In photosynthetic bacteria extensive invaginations of the plasma membrane form a set of internal membranes, also termed thylakoid membranes, or simply thylakoids, where photosynthesis occurs. All four stages of photosynthesis are tightly coupled and controlled so as to produce the amount of carbohydrate required by the plant. All the reactions in stages 1 — 3 are catalyzed by proteins in the thylakoid membrane. The enzymes that incorporate CO2 into chemical intermediates and then convert it to starch are soluble constituents of the chloroplast stroma see Figure The enzymes that form sucrose from three-carbon intermediates are in the cytosol.

Chapter 8 Photosynthesis Flow Chart Answer Key
Absorption of Light The initial step in photosynthesis is the absorption of light by chlorophylls attached to proteins in the thylakoid membranes. Like cytochromes , chlorophylls consist of a porphyrin ring attached to a long hydrocarbon side chain Figure The energy of the absorbed light is used to remove electrons from an unwilling donor water, in green plants , forming oxygen, and then to transfer the electrons to a primary electron acceptor, a quinone designated Q, which is similar to CoQ. Figure The structure of chlorophyll a, the principal pigment that traps light energy. In the porphyrin ring, a highly conjugated system, electrons are delocalized more Thus the overall reaction of stages 1 and 2 can be summarized as Many photosynthetic bacteria do not use water as the donor of electrons.

Chapter 8 Section 1 Photosynthesis Answer Key
This use of the proton-motive force to synthesize ATP is identical with the analogous process occurring during oxidative phosphorylation in the mitochondrion see Figures and The overall balanced equation is written as The reactions that generate the ATP and NADPH used in carbon fixation are directly dependent on light energy; thus stages 1 — 3 are called the light reactions of photosynthesis. The reactions in stage 4 are indirectly dependent on light energy; they are sometimes called the dark reactions of photosynthesis because they can occur in the dark, utilizing the supplies of ATP and NADPH generated by light energy. However, the reactions in stage 4 are not confined to the dark; in fact, they primarily occur during illumination. Each Photon of Light Has a Defined Amount of Energy Quantum mechanics established that light, a form of electromagnetic radiation, has properties of both waves and particles. When light interacts with matter, it behaves as discrete packets of energy quanta called photons.

Note that photons of shorter wavelength have higher energies. Chlorophyll a Is Present in Both Components of a Photosystem The absorption of light energy and its conversion into chemical energy occurs in multiprotein complexes, called photosystems, located in the thylakoid membrane. A photosystem has two closely linked components, an antenna containing light-absorbing pigments and a reaction center comprising a complex of proteins and two chlorophyll a molecules.
