A little different. ATP is a product of cellular respiration (also known as the Krebs cycle). Each cell makes about 32 ATP during the process of aerobic metabolism and about 6 during anaerobic metabolism. Here’s a funny tid bit of info that’s sure to create confusion. Adenosine is used to slow heart rate. It’s a parasympathomimetic. The phosphate that comes from cellular respiration is a tri-phosphate (made of of three different phosphate molecules. We’re talking about phosphorus, specifically, in terms of short period of high demand.
Glucose is needed for the Krebs cycle to make ATP. The electron transport chain creates the majority of the ATP- something like 26 ATP. When demand is so high, Glucose ant get the job done fast enough, but phosphorus can, but it’s not sustainable.
