The muscles of a recently deceased human can remain in a contracted state, termed rigor mortis, for several hours. What prevents the muscles from relaxing soon after death

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
