If the cell could no longer produce ATP than
It would be unable to concentrate Ca+ in the sarcoplasmic reticulum.

Explanation:
 The first performs of the SARCOPLASMIC RETICULUM is to STORE Ca IONS. Sarcoplasmic reticulum is incredibly thick in striated muscle cells and is closely related to the MYOFIBRILS (and, therefore, the MYOFILAMENTS.In cases wherever there's no ATP and therefore the Ca concentration is high within the myofibrils, the muscle fibre would be rigid, unable to either relax or contract.

Answer:

Sarcoplasmic reticulum would not be able to concentrate Ca+ back into it.

Explanation:

Sarcoplasmic reticulum refers to the smooth endoplasmic reticulum of muscle fiber. The expanded portions of the sarcoplasmic reticulum serve as calcium storage sites. During muscle cessation of muscle contraction, calcium ions are delivered back to the sarcoplasmic reticulum through active transport. The pumping of calcium ions back into sarcoplasmic reticulum uses ATP as energy source. If a cell is not able to form ATP, the sarcoplasmic reticulum would not be able to concentrate the calcium ions back into it.
