is the muscle relaxation active (require energy) or passive process?

yes,but are we need ATP as energy or just as modulater to end the interaction between actine and myosinealex8712 said:Active, thus why rigor mortis sets in after death.
dinesh said:Don't you need ATP for the atpase activity to allow reaccumulation of the caclium in the sarcoplasm.
trudub said:Yes, but that isn't what actually drives the process of relaxation, although it is necessary to maintain relaxation.
trudub said:You are, however, correct to say that it does not cost an ATP to relax the muscle. To relax, you merely need to bind a new ATP. That ATP is not used until the next contraction. So, it does require ATP but to say that it is an energy requiring process might not be exactly accurate.
what do you mean by skelaxin?lattimer13 said:NO NO NO!!!
all you need for relaxation is Skelaxin...or so the patients keep telling (demanding from) me.

Hausdaddy24 said:My anatomy textbook actually lists the reuptake of calcium into the sarcoplasmic reticulum (by an active pump) as the very first step of relaxation. without calcium in the sarcoplasm the tropomyosin-troponin complex changes shape and covers myosin binding sites which= relaxation. So yes relaxation is an active process.
