|
A disadvantage of fermentation pathways is:
|
|
they produce too many ATP
|
|
|
they use too much ATP
|
|
|
they do not create any ATP
|
|
|
they form too many NADH
|
Explanation:
Detailed explanation-1: -The cells cannot make more than 2 ATP in fermentation because oxidative phosphorylation does not happen due to a lack of oxygen.
Detailed explanation-2: -What is a disadvantage of fermentation as a process? It produces too much ATP. It only produces 2 ATP. It occurs in the absence of oxygen.
Detailed explanation-3: -Fermentation is the process of producing ATP in the absence of oxygen, through glycolysis alone. Recall that glycolysis breaks a glucose molecule into two pyruvate molecules, producing a net gain of two ATP and two NADH molecules.
