read the article and use the information to answer the following questions. muscle contraction what is the sarcoplasmic reticulum? how does it aid in the stimulation of muscle contraction? the sarcoplasmic reticulum is a specialized endoplasmic reticulum in muscle cells. it aids in muscle contraction stimulation by storing and releasing calcium ions. when stimulated, it releases calcium ions which bind to troponin. which of the following did you include in your response? check all that apply. it bathes the sarcomere in calcium. activated when muscle cells are stimulated. it stores large amounts of calcium.

Explanation:

The sarcoplasmic reticulum is a specialized endoplasmic reticulum in muscle cells. It stores large amounts of calcium and releases calcium ions when stimulated to aid in muscle contraction. The statements "It bathes the sarcomere in calcium" and "Activated when muscle cells are stimulated" are also relevant aspects related to its function in muscle contraction.

Answer:

It bathes the sarcomere in calcium.
Activated when muscle cells are stimulated.
It stores large amounts of calcium.
