Summary Introduction
Introduction:
ATP is the energy source need for the contraction of muscle fiber. During muscular contraction the myosin heads binds to the actin and pulls the actin inwards for this action energy is required and it is provided by the ATP.

How quickly would skeletal muscle fibers fatigue if they were unable to use oxygen to make ATP?
approximately 15 seconds
Approximately 30 seconds
Approximately 60 seconds
Approximately 100 seconds
approximately 180 seconds
Muscle fiber contraction and
nerve impulse conduction are
similar in that both are
response.
After death, a person no longer makes ATP, and calcium stored in the specialized endoplasmic reticulum of muscle fibers diffuses down its concentration gradient into the muscle cytoplasm. The result is rigor mortis—an unbreakable state of muscle contraction. Explain why the contraction occurs and why it is irreversible.
