Quizplus · Accepted Answer

If ATP supplies became very low in a muscle cell, all of the given options would occur. Tension development would decrease as ATP is required for muscle contraction. Cross bridges would not detach from actin, as ATP is required for this detachment. In extreme cases, contractures could occur, which is sustained involuntary muscle contraction. In death, rigor mortis can occur as the muscles become rigid due to the absence of ATP to release the cross bridges.
