glucose. glucose.
b. In fermentation, there is net gain of only b. In aerobic respiration, there is more net
two molecules of ATP. gain of ATP.
c. NADH is oxidized to NAD+ very slowly. c. NADH is oxidized to NAD+ very fast.
Amphibolic Pathway
Glucose is the favored substrate for respiration. All carbohydrates are usually
converted into glucose before used for respiration.
Fats needs to be broken down into glycerol and fatty acid, which is further broken
converted into Acetyl CoA and enter the respiratory pathway.
Proteins are broken into amino acids and further enter into Krebs cycle.
Breaking down process within living organism is called catabolism and synthesis
process is called anabolism process. So, respiration is an Amphibolic pathway.
