What role does ATP play in muscle contraction?

• It prevents contraction

• It signals the muscle to relax

• It provides energy for contraction

• It transports oxygen to the muscle

How is the sliding filament model initiated?

• By the binding of myosin to actin

• Through the absorption of calcium by troponin

• Via an action potential from the brain

• Through the release of glucose
