Complete oxidation of glucose to CO2 involves two different mechanisms for synthesizing ATP, oxidative phosphorylation and substrate-level phosphorylation. Which is true of substrate-level phosphorylation?

A. An enzyme catalyzes the transfer of a
phosphate group to ADP from an organic
molecule to form ATP.
B. Most of the ATP generated in cellular
respiration is generated by substrate-level
phosphorylation.
C. ATP is generated indirectly through the
transfer of high-energy electrons from
electron carriers to an electron transport
chain.
D. ATP is generated by release of energy
from the electron carriers NADH and FADH2.
