Detailed explanation-1: -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-2: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-3: -Glycolysis is the initial breakdown of glucose to pyruvate, a three carbon structure, in the cytoplasm. The pyruvate then moves into the mitochondrial matrix where a transition step called pyruvate oxidation takes place.

Detailed explanation-4: -Glucose is broken down by the cells in the presence of oxygen to obtain energy. Ans this process is called cellular respiration.

Detailed explanation-5: -The first step of cellular respiration involves the breakdown of glucose into a three-carbon compound called pyruvate.
