Question
Chapter 9.6, Problem 3CC
Summary Introduction
To analyze: The fate of a muscle cell that has spent all its ATP and oxygen supply.
Concept introduction:
A muscle cell is capable of both aerobic respiration and fermentation depending on whether oxygen is present or absent. Muscle cell also controls its catabolism when there is excess or drop down of ATP by feedback mechanism and through the regulation of allosteric enzyme activity at specific points.

Why or why not?arrow_forward2. We discussed how muscle spindles allow for precision of movement as a muscle lengthens, and particular muscles which require more precise movements will contain more spindles. In addition to this precision control over muscle length, there are other differences between muscles which enable more precision in how much force is generated. Consider the two graphs below which depict force generated by two different muscles as additional motor units are recruited.
