0%
b) 16 ATP
0%
c) 8 ATP
0%
d) 4 ATP
Explanation
Pyruvate, the first designated substrate of the gluconeogenic pathway, can then be used to generate glucose. Glucose is converted to pyruvic acid through glycolysis. 4ATP are produced and 2ATP are consumed Thus to convert Two molecules of Pyruvates to glucose 8ATP will be consumed and 4ATP will be produced. Net energy required = 8ATP - 4ATP= 4ATP Answer : (d)
