cholesterol, membrane proteins
What are the 6 functions of the proteins found in the cell membrane? - ✔️✔️-transport
-enzyme activity
-signal transduction (receptor proteins)
-recognition
-attachment of cytoskeleton
-adhesion (cell to cell)
There are two main types of cells within the body. What are they? - ✔️✔️Somatic and
Germ
What is a somatic cell used for? - ✔️✔️Building organs and tissues
What is a germ cell used for? - ✔️✔️Use for reproductive purposes
