In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?.
IrinaVladis [17]

Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.

Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.

A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.

During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.
