Question

Quizplus · Accepted Answer

The Krebs cycle, also known as the citric acid cycle, requires oxygen indirectly because it is part of aerobic respiration, which occurs in the presence of oxygen. Fats and carbohydrates can be converted to acetyl-coA, which then enters the Krebs cycle for energy production. This cycle does not take place in the cytosol but in the mitochondrial matrix, and it is utilized by many types of cells, not just muscle cells, for ATP production.
