Fill in the blank:
A cell’s plasma membrane is described as being a _________ because it is composed of a variety of molecules that are constantly in motion around each other.
Homework Answers
A cell’s plasma membrane is described as being a Fluid mosaic because it is composed of a variety of molecules that are constantly in motion around each other,
Mosaic means it consists of a variety of molecules like proteins, lipids, and these proteins are in continuous motion so are called fluid so the answer is fluid mosaic

The plasma membrane is composed of both lipids and proteins. The relative concentration of each in the plasma membrane is partly regulated by the A. chromosomes, which dictate the types and number of membrane molecules that are generated B. Golgi complex, which functions in sorting molecules destined for the membrane C. rough endoplasmic reticulum, which functions in the translation of mRNA into membrane proteins D. vacuoles, which transport molecules to the plasma membrane

Please fill in the blank. When an action potential moves to a nerve cell’s terminals, ------ ions enter from the extracellular environment through gated channels to promote vesicle movement. ------ are chemicals responsible for the movement of a single across a synapse between two adjacent nerve cells. Regarding heterotrimeric G protein, the ------- subunit binds to and stimulates adenylyl cyclase (AC). In heterotrimeric G proteins, the ------- and ------- subunits(s) stimulate phospholipase C. The a-subunit of a heterotrimeric G protein...
