Creatine phosphate functions in the muscle cell by:
Forming a temporary chemical compound with myosin
Breaking down ATP to ADP
Storing energy that will be transferred to ADP to resynthesize ATP
Forming a chemical compound with actin
Inducing a conformational change in the myofilaments
The Correct Answer is C
Choice A reason: Creatine phosphate does not interact directly with myosin. Its role is in energy storage and transfer, not in forming structural compounds with contractile proteins.
Choice B reason: ATP is broken down to ADP during muscle contraction, but creatine phosphate does not perform this breakdown. Instead, it helps regenerate ATP from ADP.
Choice C reason: This is the correct answer. Creatine phosphate stores high-energy phosphate groups and donates them to ADP to rapidly regenerate ATP during short bursts of intense muscular activity.
Choice D reason: Creatine phosphate does not form compounds with actin. Its function is metabolic, not structural.
Choice E reason: While ATP binding and hydrolysis induce conformational changes in myofilaments, creatine phosphate itself does not directly cause these changes. It supports ATP regeneration.

Correct Answer is D
Explanation
Choice A reason: The prime mover, or agonist, is the muscle primarily responsible for producing a specific movement, not its opposite.
Choice B reason: A synergist assists the prime mover by adding force or reducing unnecessary movement. It does not produce the opposite action.
Choice C reason: Agonist is another term for prime mover. It initiates the movement, not the opposing one.
Choice D reason: Antagonist is the correct answer. It is the muscle that opposes the action of the agonist. For example, the triceps brachii is the antagonist to the biceps brachii during elbow flexion.
Choice E reason: A fixator stabilizes the origin of the prime mover so that it can act more efficiently. It does not produce opposing movement.
Correct Answer is D
Explanation
Choice A reason: "Osseosus" is not a recognized scientific law or principle. It appears to be a misspelling or fictional term.
Choice B reason: Dalton's Law pertains to the behavior of gases, specifically the partial pressures in a mixture. It has no relevance to bone remodeling.
Choice C reason: "Calcine's" is not a known law or principle in physiology or anatomy. It may be a misrepresentation or confusion with calcitonin, a hormone involved in calcium regulation.
Choice D reason: This is correct. Wolff's Law states that bone grows and remodels in response to the mechanical stresses placed upon it. This principle explains how bones adapt to increased load or disuse by altering their density and structure.
Choice E reason: Boyle's Law relates to the pressure and volume of gases in a closed system. It is unrelated to bone physiology.
