MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis is the first step in cellular respiration that occurs in the cytoplasm within the mitochondria. Glycolysis is the process in which glucose six-carbon sugar molecule is broken down into 3C molecules to generate cellular energy.

Detailed explanation-2: -The first stage of cellular respiration is glycolysis. This process is shown in the top box in Figure 5.9. 3 showing a 6-carbon molecule being broken down into two 3-carbon pyruvate molecules. ATP is produced in this process which takes place in the cytosol of the cytoplasm.

Detailed explanation-3: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.

Detailed explanation-4: -There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.
