Question

during the decomposition of glucose in cells, some atp is generated by:
citric acid cycle
glycolysis
two of these
none of these
preparatory (prep) reaction

Explanation:

• Citric acid cycle: Produces ATP (in the form of GTP which is readily converted to ATP).
• Glycolysis: Produces a small amount of ATP (net gain of 2 ATP per glucose molecule).
• Preparatory (prep) reaction: Does not produce ATP; it converts pyruvate to acetyl - CoA.

Since both the citric acid cycle and glycolysis produce ATP during glucose decomposition in cells.

Answer:

C. two of these
