Under anaerobic conditions, a major metabolic problem of glycolysis is to __________.
A. dispose of CO2
B. generate reduced electron acceptors/carriers (e.g., NADH, FADH2, etc.)
C. regenerate oxidized electron acceptors/carriers (e.g., NAD, FAD, etc.)
D. All of theabove
E. None of the above because glycolysis does not occur anaerobically
Cell membranes are considered fluid mosaics because
A. they are mostly liquid.
B. they are composed of lipids, proteins, and carbohydrates.
C. the components can move within the membrane.
D. A and B.
E. A and C.
The ATP synthase enzyme generates ATP because it
A. Creates a H+ gradient across the internal mitochondrial membrane
B. Participates in the transfer of electrons across the cytoplasmic membrane
C. Transports H+ across the internal mitochondrial membrane and catalyzes the formation of ATP from ADP +Pi
D. Transports H+ across the internal mitochondrial membrane and catalyzes the formation of H2O from 2 H+ and ½ O2
E. None of the above
During cellular respiration, glucose is consumed and CO2 is release from the cell. Where does the oxygen in "CO2" come from?

B. From H2O in the cell.
C. From glucose.
D. From any molecule in the cell.
