Muscle Action
A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are t…

Step 1

myofibrillar proteins are proteins found in muscles that help to contract them, comprising roughly 30% of muscle mass, and they don't have an isoelectric point because this type of protein does not contain any charged amino acids.
