Question
Chapter 2, Problem 3CR
Summary Introduction
To determine:
The meaning of the passive transport of substances into a cell.
Introduction:
The cell membrane is selectively permeable, so it is able to regulate the transport of materials in and out of the cell.
Summary Introduction
To determine:
The passive processes that move the material across the plasma membrane.
Introduction:
The passive transport of molecules across the semipermeable membrane is similar to floating downstream with the current.
