Detailed explanation-1: -Glycolysis is the first step of respiration, where glucose completely breaks into CO2 and H2O.

Detailed explanation-2: -Step 1: Glucose is phosphorylated by the enzyme hexokinase to form glucose 6-phosphate. Glucose gains energy by being phosphorylated at the expense of one ATP. Step 2: Glucose 6-phosphate is converted into its isomer, fructose 6-phosphate, by an isomerase enzyme.

Detailed explanation-3: -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-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).
