Chapter 10, Problem 20CP
Summary Introduction
To review:
The reason behind classifying a few skeletal muscles as fast and others as slow.
Introduction:
The skeletal muscle fibers are mainly classified on the basis of the speed of generation of adenosine triphosphate (ATP):
Slow oxidative fibers are those, which contract slowly and use aerobic respiration for the production of ATP.
Fast oxidative fibers are those, which contract fast and use aerobic mode of respiration but, can also switch to anaerobic respiration for the production of ATP.
Fast glycolytic fibers are those that contract very fast and use anaerobic respiration for the production of ATP.

Why do skeletal muscle fibers appear striated when viewed through a light microscope?
One of the primary characteristics of all muscle tissue is contractility, the ability to shorten
(contract) and lengthen (relax). You've identified the various components of a myofibril above.
Now, use the table below to indicate what occurs to each band, line, or zone when the muscle
contracts vs. relaxes.
What occurs to this region / structure during contraction/relaxation?

Place the events in chronological order as they relate to a muscle contraction. Calcium is released from the sarcoplasmic reticulum. Myosin heads bind to actin. An action potential arrives at the axon terminal of a motor neuron. Calcium binds to troponin, displacing tropomyosin and exposing myosin head binding sites on actin. Myosin heads undergo power stroke and actin slides over myosin towards M line of sarcomere. Acetylcholine is released at the neuromuscular junction.arrow_forward
