Metabolism in Human White Muscle Fibers



Metabolism in Human White Muscle Fibers

Because our bodies use muscles for wide range of activities, different types of muscle fibers use different methods of synthesizing ATP, which are reflected in their cellular structure.

This cross-section of skeletal muscle shows two major types of muscle cells which differ in size and coloration. These structural differences relate to their method of metabolism.

Features of White Muscle Fibers
- Large in Diameter
-  Light in color due to reduced myoglobin
- Surrounded by few capillaries
- Relatively few mitochondria
- High glycogen content
