Do all the chlorophyll molecules in a photosynthetic reaction center play the same roles in the light reactions of photosynthesis?
Step by step
Solved in 2 steps
- What is the overall purpose of the light reactions in photosynthesis?Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?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?
- How is the excited state energy of a chlorophyll molecule used to drive the light-dependent reactions of photosynthesis?Where do photosynthetic organisms get the energy needed to make sugars during the light- independent/dark reactions? They use the ATP and NADPH that are produced during the light-dependent reactions. They convert the 6-carbon sugars into 5-carbon sugars. They obtain the energy directly from the Sun. They use the ADP and carbon dioxide produced during the light-dependent reactions.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.…

NADPH and ATP molecules are produced during the light reactions and are used to power the light independent reactions. NADPH and ATP molecules are produced during the light reactions, which are used to power the light dependent reactions. Sugar and ATP are produced during the light reactions, which are used to power the light independent reactions. Carbon dioxide and NADPH are produced during the light reactions, which are used to power the light dependent reactions.

STROMA (low H+ concentration) Light THYLAKOID SPACE (high H+ concentration) STROMA (low H+ concentration) Photosystem II 4 H+ H₂O 1 1/2 0₂ +2 H+ Thylakoid membrane Cytochrome complex Light Pq 4 H+ Photosystem I Pc ATP synthase ADP + H+ Fd M ATP NADP+ reductase NADP+ + H+ NADPH To Calvin CycleWhat is the relationship between the energy content of a photon and the wavelength of light? How does the wavelength of light determine whether it will stimulate photosynthesis? How do the absorbance properties of photosynthetic pigments determine the direction in which energy is transferred within a photosynthetic unit?DRAW a curved arrow mechanism for photosynthesis with the following steps. Step 1: Absorption of sunlight and excitation of chlorophyll molecules Step 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. Step 3: Electron transfer from oxidized chlorophylls to an electron acceptor, such as a quinone molecule Step 4: Electron transfer from the quinone molecule to a chain of electron carriers, such as cytochromes, which generate a proton gradient across the thylakoid membrane Step 5: ATP synthesis by ATP synthase using the energy of the proton gradient. Step 6: Transfer of electrons from the electron carriers to the enzyme rubisco, which catalyzes the carboxylation of ribulose bisphosphate (RuBP) with CO2, forming an unstable 6-carbon intermediate. Step 7: Cleavage of the 6-carbon intermediate into two 3-carbon molecules, which are phosphorylated by ATP and reduced by NADPH to form glyceraldehyde-3-phosphate (G3P) Step 8: Conversion of G3P to…
