Answer the following in complete sentences. 1. As descriptive and detailed as possible, describe what you observed after adding activating solution to your muscle sample. 2. Other than ATP, what muscle components are necessary for muscle contraction? Exp0lain the role of each component below. 3. ATP is required for several processes of muscle contraction. List and describe each. 4. Propose what would happen to a sarcomere if ATP runs out, as in after death.
Homework Answers
1) After addition of activating solution to the muscle sample, there will be contraction of individual muscle fibers
2) Apart from ATP, the muscle components that are required for contraction include muscle filaments like actin, myosin, troponin, tropomyosin, and calcium ions.
3) ATP pulls back the myosin head from actin and makes myosin ready for the next cycle.
4) If ATP runs out, the sarcomere will be in semi contracted state as the power stroke cannot takes place in the absence of ATP.
