how many molecules of carbon dioxide would be released from the complete aerobic respiration of a molecule of sucrose (C12H22O11), disaccharide

12

how many ATP molecules could be made through substrate-level phosphorylation plus oxidative phosphorylation (chemiosmosis) if you started with three molecules of succinyl CoA and ended with oxaloacetate

18

where do the catabolic products of fatty acids breakdown enter into the citric acid cycle?

Acetyl CoA

which of the following intermediary metabolites enters the citric acid cycle and is formed, in part, by the removal of a carbon (CO2) from one molecule of pyruvate?

Acetyl CoA

most of the nrg that enters electron transport enters as

FADH2 and NADH

the oxygen consumed during cellular respiration is involved directly in which process or event?

accepting electrons at the end of the electron transport chain

carbon dioxide is released during which of the following stages of cellular respiration?

oxidation of pyruvate to acetyl CoA and the citric acid cycle
