Which of the following yield ATP during contraction of muscles

Which of the following yield ATP during contraction of muscles?

Options

(a) myoglobin
(b) creatinine phosphate
(c) haemoglobin
(d) myosin

Correct Answer:

creatinine phosphate

Explanation:

Creatine phosphate is a phosphagen, which is a compound that can store energy in its phosphate bonds. In a resting muscle, excess ATP (adenosine triphosphate) transfers its energy to creatine, producing ADP (adenosine diphosphate) and creatine phosphate. When the muscle starts to contract and needs energy, creatine phosphate and ADP are converted into ATP and creatine by the enzyme creatine kinase. This reaction occurs very quickly; thus, phosphagen-derived ATP powers the first few seconds of muscle contrac
