Predict how the following conditions would affect the production of O2, ATP, and NADPH and state whether noncyclic or cyclic electron flow would occur in each;(3) blue and red photons hit a chloroplast, but a proton channel has been introduced into the thylakoid membrane, so it is fully permeable to protons.

In mechanism, photophosphorylation is most similar toa. substrate-level phosphorylation in glycolysis.b. oxidative phosphorylation in cellular respiration.c. carbon fixation.d. reduction of NADP+.

Which of the following is a false statement about photosynthesis?a. During the light-independent reactions, electrons and ATP from the light reactions combine with atmospheric carbon dioxide to produce sugars;b. The light-independent reactions take place in the chloroplast stroma;c. Oxygen produced during the light-independent reactions is released into the atmosphere;d. Chlorophyll absorbs blue and red light and reflects green light;e. The end product of photosynthesis is a carbohydrate such as glucose.

Which process is most directly driven by light energy?a. creation of a pH gradient by pumping protons across the thylakoid membraneb. reduction of NADP+ moleculesc. transfer of energy from pigment molecule to pigment moleculed. ATP synthesis

Which of the following correctly identify a role of the ATP produced in the light-capturing reactions? Select True or False for each statement.T/F It is used by rubisco to fix CO2 to RuBP.T/F It serves the same role as ATP produced by mitochondria.T/F It is used to regenerate RuBP from G3P molecules.T/F It is used to produce G3P molecules

Predict how the following conditions would affect the production of O2, ATP, and NADPH and state whether noncyclic or cyclic electron flow would occur in each;(2)blue and red photons hit a chloroplast, but no NADP+ is available

Predict how the following conditions would affect the production of O2, ATP, and NADPH and state whether noncyclic or cyclic electron flow would occur in each: (1) Only blue photons hit a chloroplast

Predict how the following conditions would affect the production of O2, ATP, and NADPH and state whether noncyclic or cyclic electron flow would occur in each: (1) Only blue photons hit a chloroplast

An investigator exposes chloroplasts to 700-nm photons and observes low O2 production, but high ATP production. Which of the following best explains this observation?a. The electrons from water are directly transferred to NADP+, which is used to generate ATP.b. Photosystem II is not splitting water, and the ATP is being produced by cycling electrons via photosystem I.c. The O2 is being converted to water as a terminal electron acceptor in the production of ATP.d. Electron transport has stopped and ATP is being produced by the Calvin cycle.
