Question
Chapter 18, Problem 25P
Interpretation Introduction
a) Pyruvate
Interpretation:
To calculate the amount of ATP produced by one molecule of pyruvate.
Concept introduction:
ATP (adenosine triphosphate) is the energy source in the human body. It is formed in mitochondria, due to this, mitochondria are also termed as the powerhouse of the cells. ATP contains three highly energetic phosphate groups. When any kind of energy consuming activity is performed by the body, then these phosphate groups get hydrolyzed from ATP, yielding a large amount of energy.
