) Will the duration of the latency period of the single contractions of a muscle fibre be the
same when it lifts loads with different weight?
Answers
Answer:
Contraction of a Muscle Fiber. A cross-bridge forms between actin and the myosin heads triggering contraction. As long as Ca++ ions remain in the sarcoplasm to bind to troponin, and as long as ATP is available, the muscle fiber will continue to shorten.
