Question

At any given moment, how many molecules of atp are there in each of our cells? How many atp phosphate bonds are used and replaced every two or three minutes? How many kilograms of atp does a human body recycle every day what does the process of cellular respiration do to avoid this outcome?

Answer 1

A single cell uses about 10 million ATP molecules per second, and recycles all of its ATP molecules about every 20-30 seconds. An arrow shows the bond between twophosphate groups in an ATP molecule. When this bond breaks, its chemical energy can do cellular work

ATP stands for adenosine triphosphate. The word triphosphate indicates that the molecule has 3 phosphate groups. ATP stores energy within the bonds between phosphate groups, especially the second and third.

Totally quantity of ATP in an adult is approximately 0.10 mol/L. Approximately 100 to 150 mol/L of ATP are required daily, which means that each ATP molecule is recycled some 1000 to 1500 times per day. Basically, the human body turns over its weight in ATP daily.


Steps of cellular respiration. Duringcellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
