If a mutation occurs such that photosystem II no longer functions as efficiently as it should, which of the answer choices would be most directly affected? the amount of O2 produced the rate at which NADPH is produced the rate at which protons are transported into the thylakoid the rate of ATP synthesis by ATP synthase in the chloroplast

Which of the following would still be possible in a plant with nonfunctional mitochondria in the dark? Select all that apply.   Krebs cycle   Calvin cycle   Oxidative phosphorylation   Cyclic photophosphorylation   Glycolysis   Noncyclic photophosphorylation

Amy's plants were growing nicely, but she accidentally knocked over some herbicide into one plant and it killed it. she looked on the box and it stated it worked by acting as a final electron acceptor in the chloroplast. How would this affect the following measures as compared to a normal plant?      More Less Same Chlorophyll       G3P level       Oxygen production       ATP production       NADPH production

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 correct

What special adaptation has evolved in CAM plants such as cacti and stonecrops that allows CO2 fixation and the Calvin cycle to occur in the same cell, but still occur separately? Briefly describe how this separation of events works.

Choose 2 of the following terms: Z protein / ATP synthase / Photosystem II. What is the specific role of each of the following? Describe what and how the protein does its job. As well, explain the importance of each in the overall process of photosynthesis.

Which of the following descriptions about photosystems during linear electron flow is not correct? Select one: a. energy required for ATP synthesis is provided when electrons pass through the electron transport chain from photosystem I b. photosystem II works before photosystem I c. P680 is the chlorophyll a pair that exists in photosystemII d. the primary electron acceptor receives electrons from P680 or P700 e. P680+ receives electrons from the splitting of water

if mutation makes photosystem I function less efficiently, which of the following is most directly affected? rate of ATP sythesis by ATP sythase in cholorplast? Rate at which protons are transported into thylakoid? Rate at whinch NADPH is produce? a mount of O2 produced?

Why would “knocking out” a gene for a chloroplast fatty acid desaturase (an enzyme involved in synthesizing fatty acids containing three double bonds) increase the rate of photosynthesis at 40°C, a temperature at which photosynthesis is normally impaired?
