To compare: The activity of tropomyosin and troponin in muscle contraction with that of the activity of competitive inhibitors in the enzyme action. Introduction: Muscles are an essential part of the body as they help the body in movement and generation of energy. The system involving the muscles is called the muscular system. It allows the movement of the muscle by contraction or relaxation. The three types of the muscles are the skeletal muscles, the smooth muscle and the cardiac muscles.

Skeletal muscle myosin heavy chain is a mechanoenzyme that requires ATP for its function. Other enzymes, such as phosphofructokinase-2, also rely on ATP. How are PFK-2 and myosin Il different in their use of ATP? • View Available Hint(s) Both enzymes use ATP in the exact same way. PFK-2 functions as a kinase, whereas myosin functions as a phosphatase. PFK-2 catalyzes ATP hydrolysis, whereas myosin does not. Myosin catalyzes ATP hydrolysis, whereas PFK-2 does not. PFK-2 binds to ATP or ADP + Pj, whereas myosin undergoes covalent modification via phosphorylation. Submit

Reflect back on the Muscle Fatigue investigation we did earlier in this Activity. Choose one of your classmate’s interpretation to one of these questions: What happened to your energy & ability to pinch the clothespin as you progressed through each trial? Why? What might cause one to be able to get more squeezes, in other words, to have less fatigue? Explain in terms of biological concepts. Suggest how the amount of ATP produced cause your muscle cells to be less efficient. When did this change in the amount of ATP produced occur in this investigation? How could you tell? Your muscles would probably recover enough after 10 minutes to operate at the original efficiency. Explain why. Show how specific details from the steps of cellular respiration add details to answer this question.

First, explain how resting membrane potential is established in terms of ion concentration and electric charge. Next, explain the process of neural signal transmission from an alpha motor neuron to the muscle fiber. Do this by explaining how an AP is generated (ions and membrane proteins) at the neuron, how the signal is propagated, what happens at the axon terminal, what happens at the motor endplate, and explain all the molecular events that occur to cause muscle contraction.
