Question

For two molecules of glucose, glycolysis uses and produces ATP molecules

Answer 1

Glycolysis

The pathway of the breakdown of glucose into pyruvic acid is termed as glycolysis. This pathway is a step-wise process in which several molecules are released like 4 ATPs, 2 ADPs, water and 2 (NADH + $H^{+}$ ) when one glucose molecule undergoes glycolysis.

ATP used

Number of ATP used per glucose molecule = 2
Number of ATP used for 2 glucose molecule
$=2\times 2=4$


ATP produced

Number of ATP produced per glucose molecule = 4
Number of ATP produced for 2 glucose molecule
$=4\times 2=8$


Final answer: (A) 4 and 8
