Question 1

Fate of pyruvate under aerobic and fed conditions

Answer 1

converted to acetyl CO A for TCA cycle

converted into alanine for proteins synthesis by alanine aminotransferase

Question 2

Answer 2

converted into oxaloacetate for gluconeogenesis

Question 3

Fate of pyruvate under anaerobic conditions

Answer 3

reduced to lactate for the cori cycle

converted to alanine for glucogenesis and urea cycle

Question 4

Alanine aminotransferase

Answer 4

converts pyruvate to alanine for protein synthesis, gluconeogenesis and urea cycle
