[18]protein that accelerate the conversion of reactants to products. They do not change the energy relationships between reactants and products

[19]A model that describes the structure of cell membranes. In this model, a flexible layer made of lipid molecules is interspersed with large protein molecules that act as channels through which other molecules enter and leave the cell.


[21]Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. Enzymes carry out almost all of the thousands of chemical reactions that take place in cells.

[22]trans membrane proteins

[23]The regulatory protein subunits of many ion channels and transmembrane receptors

call to cell signaling

[24]trans membrane


[26]Polar - hydrophilic (tips of membrane)

Nonpolar- hydrophobic (inside membrane)

Charged - hydrophilic (tips of membrane)
