Q931

Pyruvic acid, the last product of glycolysis, is degraded to CO2 and H2 in

A.
Cytoplasm
B.
Inner membrane of mitochondria
C.
Matrix of mitochondria
Answer
D.
Matrix of chloroplasts

Answer: Option C

Solution

Answer: Option C
Solution:
Pyruvic acid, the last product of glycolysis, is degraded to CO2 and H2 in the Matrix of mitochondria.
Glycolysis is a cytoplasmic pathway that breaks down glucose into two three-carbon compounds and generates energy.
The final step of glycolysis is catalyzed by pyruvate kinase to form pyruvate and another ATP. During fasting, glucagon activates protein kinase A which phosphorylates pyruvate kinase to inhibit it.
