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, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.

Detailed explanation-3: -Step 1: Hexokinase In the first step of glycolysis, the glucose ring is phosphorylated. Phosphorylation is the process of adding a phosphate group to a molecule derived from ATP. As a result, at this point in glycolysis, 1 molecule of ATP has been consumed.

Detailed explanation-4: -Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.

Detailed explanation-5: -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.
