Question

Substrate level phosphorylation does not occur in which of the following reaction of aerobic respiration? (A) 1,3 -diPGA longrightarrow 3-P G A (B) 3-PGA longrightarrow 2-P G A (C) PEP Pynuvate (D) Succinyl CoA longrightarrow Succinic acid

Substrate level phosphorylation arrow Direct transfer of a phosphate group from a substrate molecule to ADP to form ATP. There is no such transfer from 3PGA - 2PGA. In the phosphate group reshuffling is done here from 3 text rd position to 2 text nd position.

Q. Substrate level phosphorylation does not occur in which of the following reaction of aerobic respiration?

1,3 -diPGA $⟶ 3 - PG A$

3-PGA $⟶ 2 - PG A$

PEP Pynuvate

Succinyl CoA $⟶$ Succinic acid

Substrate level phosphorylation $\to$ Direct transfer of a phosphate group from a substrate molecule to ADP to form ATP.
There is no such transfer from $3 PG A - 2 PG A$ . In the phosphate group reshuffling is done here from $3^{rd}$ position to $2^{nd}$ position.

Q. Substrate level phosphorylation does not occur in which of the following reaction of aerobic respiration?

1,3 -diPGA ⟶3−PGA

3-PGA ⟶2−PGA

PEP Pynuvate

Succinyl CoA ⟶ Succinic acid

Substrate level phosphorylation → Direct transfer of a phosphate group from a substrate molecule to ADP to form ATP. There is no such transfer from 3PGA−2PGA. In the phosphate group reshuffling is done here from 3rd position to 2nd position.
