Question
Chapter 11, Problem 36RQ
Summary Introduction
To review:
The three mediator proteins that move the phospholipid molecule from one side of a membrane to the other, and the requirement of these proteins.
Introduction:
One of the basic principles of the Fluid mosaic model is that the constituents move freely within the cell membrane. It is possible that the components can move freely through rotational, lateral, andtransversemovements.
