Answer 1

The correct answer is:

(a) True

Muscles, particularly skeletal muscles, act as reservoirs for calcium. When a muscle contracts, calcium is released from its internal stores (in the sarcoplasmic reticulum), which is essential for muscle contraction. Additionally, muscles are involved in the regulation of phosphorus, which is vital for energy metabolism, though bones are the primary reservoir for phosphorus in the body.
