The glyoxylate cycle enzymes
A) are active at night when sugar reserves are high and lipid synthesis is activated.
B) bypass the decarboxylation steps of the TCA cycle, resulting in the net synthesis of a sugar molecule from acetyl-CoA.
C) replace the mitochondrial TCA cycle enzymes.
D) require ATP and NADPH from the light reactions.

Question

Quizplus · Accepted Answer

The glyoxylate cycle enzymes bypass the decarboxylation steps of the TCA cycle, resulting in the net synthesis of a sugar molecule from acetyl-CoA. This allows for the conversion of stored lipids into usable sugars, which can be useful during certain periods of growth or when resources are scarce. The other options presented are not accurate descriptions of the glyoxylate cycle enzymes.
