Question

At the end of glycolysis, X is the net energy gain from one molecule of glucose via Y, but there is also energy stored in the form of Z. identify X, Y, and Z.

• A. X- 1 ATP ; Y-Oxidative phosphorylation ; Z - NADH+$H^{+}$
• B. X- 2 ATP ; Y-Oxidative phosphorylation ; Z - NADH+$H^{+}$
• C. X- 1ATP ; Y-Substrate level phosphorylation ; Z - $FAD{H}_2$
• D. X- 2ATP ; Y-Substrate level phosphorylation ; Z - NADH+$H^{+}$
  

Answer 1

The correct option is D X- 2ATP ; Y-Substrate level phosphorylation ; Z - NADH+$H^{+}$

In Glycolysis the net energy gain from one molecule of glucose by phosphorylation of different substrate (i.e., Substrate level phosphorylation) produced 2 ATP. In between this process, $2NA{D}^{+}$ gets reduced and stored as an energy source to use later.

Thus, X- 2ATP, Y- Substrate level phosphorylation, Z- $NADH$ + $H^{+}$.

So, the correct option is (D).
