How many ATP molecules are generated during the complete oxidative degradation of each of the following metabolites to CO2 and H20?
A) Acetyl CoA = __________
B) Pyruvate = ____________
C) Glucose = ____________
D) Glycerol (hint: enters glycolysis through DHAP) = _____________
E) Aspartic acid (hint: enters citric acid cycle through oxaloacetate) = _____________

Respuesta :

Answer:

A) Acetyl CoA produces 10 molecules of ATP. The acetyl CoA goes through one round of the TCA cycle and generates three molecules of NADH (3 * 2.5 = 7.5), one molecule of FADH2 (1*1.5 = 1.5) and one molecule of ATP.  

B) Pyruvate produces 12.5 molecules of ATP. Pyruvate generate four molecules of NADH (4*2.5 = 10), one molecule of FADH2 (1*1.5 = 1.5) and one molecule of ATP.  

C) Glucose produces 32 molecules of ATP. Glucose produces ten NADH (10*2.5 = 25), two FADH2 (2*1.5 = 3) and four molecules of ATP.  

D) Glycerol produces 17 molecules of ATP. Glycerol produces five NADH, one FADH2 and three molecules of ATP.  

E) Oxaloacetate produces 20 molecules of ATP. Oxaloacetate produces six NADH, two FADH2 and two molecules of ATP.
