After a skeletal muscle fiber is treated with a membrane permeable drug that speeds up the action of the SR Ca+2-ATPase, how would contraction differ after multiple and frequent action potentials? fused tetanus would be reached in the same amount of time as an untreated fiber fused tetanus would be reached sooner than an untreated fiber the maximal tension would be increased compared to an untreated fiber

The correct Answer is "Fused tetanus would be reached sooner than an untreated fiber"

Explanation:

Muscle has a pair of stages - reduction and moderation. Reduction is trailed by a obstinate section once no reduction will occur upon inspiration. This can be the section once the sr ca2+ ATPases are vigorous and are driving the calcium back to the sarcoplasmic reticulum. Once this the forces decrease. If the inspiration are common enough to remove the relief amount, then it's known as a amalgamate tetanus. The quicker the sr ca2+ drives effort, the smaller are the biological time and therefore the faster amalgamate tetanus would be extended.
