Question

From the choices below, identify processes important for generating atp in the presence of oxygen. (there may be more than one correct answer. select all that apply.) glycolysis breaks glucose down into pyruvate the citric acid (krebs) cycle generates high-energy carriers such as nadh that will be used later on in the etc the etc establishes a proton gradient between the two mitochodrial membranes protons flow through the atp syntase, an enzyme that uses this flow to generate lots of atp

Answer 1

The best answer choice is:

The Krebs cycle generates high-energy carriers such as NADH that will be used later on.

The Krebs cycle produces ATP in the presence of oxygen. If oxygen is present, aerobic respiration can occur. Aerobic respiration produces much more ATP than anaerobic processes. During the process of Krebs, electrons are passed along an electron transport chain and are picked up by an electron acceptor. The energy of these electrons is used to produce a hydrogen ion concentration gradient, which provides the energy needed to make ATP.
