ANS-a- 2 phosphoglycerate is glyceric acid which serves as the substrate in the ninth step of glycolysis.it is catalysed by enolase into phosphoenolpyruvate,the penultimate step in the conversion of glucose to pyruvate. total ATP yield produce at the process is 2 ATP.
ANS-b- It is known as glucose alanine cycle has an energy cost,equal to 3-5 ATP.
ANS-c- It is known as TCA (citric acis cycle) cycle in which toatal 36 ATP are formed.
