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.
