Proteins are used for many structural functions such as in the actin and myosin in muscle or as a part of the cytoskeleton scaffolding that maintains cell shape. what other main function do proteins serve? a. as waterproof membranes to regulate the transport of molecules in and out of the cell b. as cellulose to form the major structural component of plant cell walls c. as enzymes to control the rate of reactions and regulate cellular activity d. as coding for genotypic expression and phenotypic traits reset

C.  As enzymes to control the rate of reactions and regulate cellular activity.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
