In mechanism, photophosphorylation is most similar to

oxidative phosphorylation in cellular respiration

Most CO2 from catabolism is released during

citric acid cycle

which metabolic pathway is common to both fermentation and cellular respiration of a glucose molecule?

glycolysis

the light reactions supply the calvin cycle with

ATP and NADPH

The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the

H+ concentration gradient across the membrane holding ATP synthase

which of the following sequences correctly represents the flow of electrons during photosynthesis

H2O → NADPH → Calvin cycle

how is photosynthesis similar in C4 plants and CAM plants

In both cases, rubisco is not used to fix carbon initially.

the final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation is:

O2

When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs?

The pH of the matrix increases.

which of the finding statements is a correct distinction between autotrophs and heterotrophs?

autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic

which of the following occurs during the calvin cycle

carbon fixation

in mitochondria, exergonic redox reactions

provide the energy that establishes the proton gradient.

what is the oxidizing agent in the following reaction? pyruvate + NADH + H+ yields lactate + NAD+

pyruvate

Which process is most directly driven by light energy?

transfer of energy from pigment molecule to pigment molecule
