21. Which statement best describes how sugars are metabolized in herbivores that eat clover containing high levels of cyanide?
A. Fermentation and the Krebs cycle metabolize sugars and produce
sufficient ATP to sustain life.
B. Aerobic respiration and photosynthesis partially metabolize sugars and
store metabolic intermediates until the levels of cyanide are reduced.
c. Glycolysis metabolizes sugars more efficiently than it does in the
absence of cyanide and produces the normal amount of ATP per sugar
molecule.
D. Glycolysis and fermentation metabolize sugars but do not produce
sufficient ATP to sustain life.
