Detailed explanation-1: -Glucose is a kind of biomolecule that is rich in carbohydrates. It is catabolized into 3-carbon pyruvic acid. These three-carbon molecules get oxidized into NADH and ATP. This reaction takes place during the first stage of cellular respiration called glycolysis.

Detailed explanation-2: -Glucose, a 6-carbon sugar, is a simple carbohydrate or “mono-saccharide.” Sugar is a source of quick energy for the body because it is easily metabolized (broken down). Larger, more “complex carbohydrates” are made by stringing together chains of glucose subunits into di-saccharides, tri-saccharides, poly-saccharides.

Detailed explanation-3: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).

Detailed explanation-4: -Catabolism is the part of the metabolic process that breaks down large, complicated molecules into smaller ones in order to produce energy. The energy is released as a result of the destructive branch of metabolism.
