To produce ATP (adenosine triphosphate) in muscles, creatine phosphate (CP) transfers _ to adenosine diphosphate (ADP).
Correct answer: D. Phosphate
- A. Oxygen
- B. Adenosine
- C. Cytosine
- D. Phosphate
Explanation
By adding a phosphate group, ADP is transformed into ATP. The phosphate group is transferred by creatine phosphate, which forms creatinine as a by-product. Hence, this option is the correct one.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
