Answer:the following processes directly require ATP includes:
B (Release of cross-bridge (interaction) between actin and myosin.)
C (Movement of calcium ions back into the sarcoplasmic reticulum after contraction.)
Explanation:
Muscle contraction occurs in various parts of the body to ensure proper body functioning. This process requires the release of calcium ion and the use of ATP ( Adenosine Triphosphate) as source of energy at various levels for the process to take place. The distinct role of ATP in muscle contraction includes:
-ATP is directly required as it causes detachment from actin after power stroke when it binds at one of the reactive sites of myosin. This explains option B (Release of cross-bridge (interaction) between actin and myosin.)
-it powers the pump that transports calcium ions back into the sarcoplasmic reticulum after contraction. This explains option C (Movement of calcium ions back into the sarcoplasmic reticulum after contraction)
- it activates the myosin head so it can bind to actin and rotate by the action of ATpase enzyme.
Answer: Magnetic field data
