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 the first twitch differ? 1 point the twitch would last the same amount of time the twitch would be shorter the twitch would produce more tension the twitch would last longer

The passive diffusion rate of penetrated molecules through the biomembrane can be used to quantify a membrane's permeability. It is widely acknowledged that a single molecule's permeability is primarily influenced by its size, polarity, charge number, and molar mass.

Muscle goes through two stages: moderation and decrease. Once no reduction will occur upon inspiration, reduction is followed by an obstinate section. When the sr ca2+ ATPases are active and moving calcium back to the sarcoplasmic reticulum, this is the portion that occurs. The forces then start to decrease. The condition is referred to as an amalgamate tetanus if the inspiration are frequent enough to eliminate the relief quantity. The biological period is shorter and the amalgamate tetanus would be extended more quickly with faster sr ca2+ drives effort.
