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: -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).

Detailed explanation-3: -Phase 1: The “Priming Step" The first phase of Glycolysis requires an input of energy in the form of ATP (adenosine triphosphate). alpha-D-Glucose is phosphorolated at the 6 carbon by ATP via the enzyme Hexokinase (Class: Transferase) to yield alpha-D-Glucose-6-phosphate (G-6-P).

Detailed explanation-4: -(i) In aerobic respiration, glycolysis occurs in the cytoplasm of a cell. (ii) In aerobic respiration, glycolysis cannot occur without the presence of oxygen. (iii) In the process of glycolysis, glucose molecules are oxidised to produce the molecules of pyruvate.
