A) Acetyl Co-A
B) Citric acid
C) Succinic acid
D) Lactic acid
Correct Answer: D
Solution :
Lactic acid is formed by the process of fermentation. Lactic acid bacteria can ferment lactose sugar formed in milk. Enzyme involved in this fermentation is lactic dehydrogenase. Acetyl Co-A is the starting substance of Krebs cycle. It is formed by acetylation and oxidative decarboxylation of pyruvic acid. Acetyl Co-A combines with 4 carbon oxaloacetic acid to form 6 C citric acid. Succinyl Co-A (4C) combines with \[{{H}_{2}}O\] to form succinic acid and Co-A is regenerated. This is substrate level phosphorylation (formation of GTP).You need to login to perform this action.
