Current Question (ID: 11540)

Question:

In which of the following conversion steps occurring in the mitochondrial matrix, substrate-level phosphorylation occurs?

Options:

1. 1, 3-bisphosphoglyceric acid → 3-phosphoglyceric acid
2. Glucose-6-phosphate to fructose-6-phosphate
3. α-ketoglutaric acid → Succinyl CoA
4. Succinyl CoA → Succinic acid

Solution:

Substrate-level phosphorylation is a process of ATP synthesis where a high-energy phosphate group is transferred from a phosphorylated intermediate to ADP to form ATP. This process occurs in the mitochondrial matrix during the conversion of Succinyl CoA to Succinic acid in the Krebs cycle.
