A: Unfortunately, many long-term effects of medications are not known since many medications are not studied for over 6 to 12 months. Adderall (amphetamine/dextroamphetamine) is a medication that has been used for many years in the treatment of ADHD and narcolepsy.
Answer by Nicole Cooper. Confidence votes 32. The role ATP plays in muscle contraction is that ATP binds to sites on myosin heads, inducing a conformational change in the actin binding site and reducing the affinity for the actin substrate. Hydrolysis of ATP then cocks the myosin head and moves it closer to the z disk.
The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) â the bodyâs biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells.So once muscle contraction starts, the making of more ATP must start quickly.he source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) â the bodyâs biochemical way to store and transport energy.
