cellular respiration Cellular respiration begins with glucose. Glucose is the primary saddle away used in glycolysis, the first stage of cellular respiration. This touch is found in the gel-like substance called cytoplasm that fills the cell. In glycolysis, glucose undergoes phosphorylation by ATP. The ATP is converted second to ADP. The glucose mote is rearranged and undergoes a consequence phosphorylation by ATP. The second ATP is also converted back to ADP. Glucose, a six-carbon molecule, is split into 2 three-carbon molecules of PGAL. As oxidization takes place, nicotinamide adenine dinucleotide picks up a hydrogen atom from each(prenominal) molecule to ready 2NADH.
Phosphorylation takes place again. For each molecule, 2ADP combine with mates phosphates to form a total of 4 ATP, and pyruvic acid molecules argon formed. A net gain of 2 ATP digest been formed. As the pyruvic acid molecules make their way toward the mitochondria, two more(prenominal) molecules of NADH are formed. A carbon atom also breaks bump off and combines with two ox...If you want to get a full essay, monastic order it on our website:
