diisopropylphosphofluoridate, reacts with a serine OH group in the active site of esterases such as acetylcholinesterase/chymotrypsin, whilst the organomercury compound p-hydroxymercuribenzoate reacts with a cysteine group, in both cases resulting in covalent bond formation and enzyme inhibition.

#Unit 2. Cellular Organization

Muscle cells have an abundant, modified smooth ER called the sarcoplasmic reticulum.

The release and reuptake of Ca2+ by the sarcoplasmic reticulum trigger myofibril contraction and relaxation, respectively
