Question
The immediate source of energy for muscle contraction is
The immediate source of energy for muscle contraction is
Open in App
Solution
The correct option is A ATP
Muscle contraction uses ATP as an immediate source of energy. The myosin heads hydrolyse ATP and use the energy released to bind and pull actin filaments towards the centre of the sarcomere. This movement of the actin filaments is what causes muscle contraction.
Phosphocreatine is a phosphorylated creatine molecule that serves as a reserve of high-energy phosphates in skeletal muscle to replenish ATP.
Glycogen is a stored form of carbohydrates which is broken down to make ATP.
Phosphocreatine kinase is an enzyme involved in the conversion of creatine to phosphocreatine and uses ATP.
