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.
ATP is the molecule needed for muscle contraction. Since muscle cells use up ATP at a high rate, they have ways of making ATP quickly. Muscle cells have high amounts of molecules that help generate new ATP. NAD+ and FAD+ are molecules that carry electrons in the form of NADH and FADH2, respectively.
