- 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 correctWhich of the following statements is/are TRUE for photosynthesis? The e- moves from H20 to NADP+. Some of the products from the dark reaction are required in the light reaction. It is an exergonic process that naturally by using energy from light It Involves conversion of 02 to H20 and C02 to glucose.The figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different? 400 500 600 700 Wavelength of light (nm) O Green and yellow wavelengths inhibit the absorption of red and blue wavelengths. O Oxygen given off during photosynthesis interferes with the absorption of light. O Other pigments absorb light in addition to chlorophyll a. Absorbance of chlorophyll a Violet Blue Green Yellow Orange Red - Rate of photosynthesis
- Which of the following processes during photosynthesis is incorrectly coupled to its typical location? Select one: a. Rubisco catalyzes carbon fixation—stroma b. ATP is produced via ATP synthase—thylakoid lumen c. NADPH is oxidized to NADP+—stroma d. Oxygen gas is produced by splitting of water—thylakoid lumen e. Activated P680 donates an electron to the primary electron acceptor—thylakoid membranesDRAW 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…Which of the following is TRUE about CAM photosynthetic pathway? Compared to the C3 and C4 pathways, CAM photosynthesis results in greater transpiration and water loss. O By separating where carbon is initially fixed inside the leaf tissue, CAM plants can better control the gradient of carbon dioxide between the air and their leaves. CAM photosynthesis is more energy efficient than C3 photosynthesis. Compared to C3 and C4 photosynthetic pathways, the rate of CAM photosynthesis is limited.
- Bacterium Y is photosynthetic. You want to decrease the ability of Bacterium Y to produce glucose through photosynthesis. Explain how you could manipulate the light reactions of photosynthesis to decrease glucose production during the dark reactions in Bacterium Y. Include the name of the pathway that makes glucose during the dark reactions, which/how molecules from the light reactions are used in this pathway, and what specific steps of this pathway would be affected by your manipulations.Which of the following statements is TRUE? Select one: a. The immediate product of the light energy absorbed by the P680 reaction center is used to produce NADPH. b. In cyclic photophosphorylation, the chlorophyll is reduced by electrons liberated from water molecules. c. The O2 gas produced during photosynthesis is derived from CO2. d. In noncyclic photophosphorylation, electrons from water are used directly for the reduction of P700. e. All of the statements are false.Draw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.
