Step by step
Solved in 2 steps
- For most plants, two distinct photosystems (Photosystem I and Photosystem II) work together in series during photosynthesis. These photosystems are complexes of proteins and pigment molecules. Statement 1: Photosystem I has an absorption maximum of 680 nm, whereas Photosystem II has an absorption maximum of 700 nm. Statement 2: The special pair of chlorophyll a molecules in the reaction center of photosystem I is designated as P700, whereas the special pair of chlorophyll a molecules in the reaction center of photosystem II is designated as P680. Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true. Both statements are true. Both statements are false.What enzyme fixes CO2 in the cytosol of a mesophyll cell in a C4 plants? Why is the C4 photosynthesis called C4 photosynthesis?There are two photosystems involved in the light reaction of photosynthesis. Both take upenergy from the sun in the form of light.A. Where are the photosystems located and what is the name of the organelle? B. Where does the energy that the photosystems take up, go? Describe for eachphotosystem WHERE the energy ends up at the end of the light reactions. In otherwords, what products contain the energy from which photosystem at the end ofthe light reaction?
- Not all plants have leaves that are green. Zebrina sp. has purple leaves. However, these plants are still photoautotrophic and so contain all of the expected components of photosynthesis. Explain how it is possible that these leaves are purple and can photosynthesize when you know that the photosynthetic pigment chlorophyll causes leaves to look green yet these are purple and not given.In the Light Reaction of Photosynthesis, the sun excites electrons in pigment molecules in the photosystems. These excited electrons and (H+ ions) go through electron transport systems. Keep in mind that if this process continued as stated, the pigment molecules would run out of electrons, but fortunately there is a way in which the excited electrons are replaced. Explain how the electrons are ultimately replaced and what the important byproduct is.What are the two places where light energy is required in the light reaction of photosynthesis? Why must energy be supplied at precisely these points?
- Which of the following statements about the light reactions of photosynthesis are correct? 1. Absorption of light does one thing: it makes chlorophyll easier to oxidize. 2. In PSII, the rate of damage to the D1 protein can never exceeds the rate of repair. 3. Electron transport is spontaneous (exergonic) as electrons move from P680* to P700+. 4. Compared to anoxygenic photosynthesis, in oxygenic photosynthesis less light needs to be absorbed to reduce NADP+. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correctIn terms of the spatial organization of photosynthesis within the chloroplast, what is the advantage of the light reactions producing NADPH and ATP on the stroma side of the thylakoid membrane?In the light-dependent reaction of photosynthesis, what specifically happens in the electron transport chain between Photosystem II and Photosystem I? The excited electron accepted by the primary acceptor in Photosystem II is transferred to pheophytin and plastoquinones, then to cytochrome complex, and finally to plastocyanin. Plastocyanin then transfers the electron to the P700 in the reaction center complex of Photosystem I. The excited electron accepted by the primary acceptor in Photosystem I is transferred to pheophytin and plastoquinones, then to cytochrome complex, and finally to plastocyanin. Plastocyanin then transfers the electron to the P700 in the reaction center complex of Photosystem II. The excited electron accepted by the primary acceptor in Photosystem I is transferred to plastocyanin, then to cytochrome complex, and finally to pheophytin and plastoquinones. Plastoquinone then transfers the electron to the P700 in the reaction center complex of Photosystem II.…
