MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis is the first phase in cellular respiration where glucose is converted into pyruvic acid and 2 ATPs are produced. This process takes place in the cytoplasm. Pyruvate is the end product of glycolysis that can be used in either anaerobic respiration or aerobic respiration.

Detailed explanation-2: -There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs.

Detailed explanation-3: -The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH2. A small amount of ATP is also made during this process. This process occurs in a continuous cycle, named after its discover, Hans Krebs.

Detailed explanation-4: -Glycolysis as the First Stage of Cellular Respiration Glycolysis, which literally means “splitting sugars", is the first step of cellular respiration. The process of glycolysis involves ten enzymatic reactions to convert one molecule of glucose into two molecules of pyruvate.
