Detailed explanation-1: -Glucose begins its breakdown outside of the mitochondria in a metabolic pathway called glycolysis. However, the majority of the reactions that produce ATP happen within the mitochondria (in eukaryotic cells; Figure 13.2.

Detailed explanation-2: -No, glycolysis does not takes place in the mitochondria. It occurs in the cytosol.

Detailed explanation-3: -Glycolysis. Glycolysis, the process of converting glucose into pyruvate, is the first step of cellular respiration. In contrast to every other pathway of cellular respiration, glycolysis occurs in the cytoplasm of the cell. It is the only step to occur outside of the mitochondria.

Detailed explanation-4: -Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).
