Predict what would happen to skeletal muscles of the body if an individual exposed to chemicals that inhibited the ATPase activity of myosin

What would happen to a muscle that was exposed to a drug that mimicked Ca2+ by binding to troponin irreversibly? Group of answer choices Severe muscle contraction Paralysis Nothing. Troponin is irrelevant to muscle contraction Joy, elation

Poor blood circulation will likely reduce the contraction power of a person's  myosin  actin  fast twitch fibers  slow twitch fibers

A sprinter would experience muscle fatigue sooner than marathon runner due to

On the molecular level, why does lifting weights consume energy? A. To contract a muscle, acetylcholine binds and pulls calcium ions. ATP binding and hydrolysis are required in the cycle of acetylcholine and calcium-binding and unbinding. B. To contract a muscle, myosin and actin filaments shorten, requiring ATP binding and hydrolysis. O C. To contract a muscle, myosin binds and pulls actin, ATP binding and hydrolysis are required in the cycle of myosin and actin-binding and unbinding. D. To contract a muscle, acetylcholine and calcium filaments shorten, requiring ATP binding and hydrolysis.

Suppose a substance were to prevent calcium ions from being returned to the sarcoplasmic reticulum in a skeletal muscle cell. Predict how a muscle cell would respond to being exposed to the supposed compound after a single stimulus by the motor neuron

Explain the concept of the following in regard to muscle cells: power stroke does not need to be a super indepth answer

Given that the wants to preserve energy supplies that could be needed during high intensity events, what is prefentially used in muscle most of the time to make ATP? Ketones Phosphocreatine Glucose Amino acid Fatty acid
