Active and Bulk Transport. Active Transport passive transport is useful for many metabolic functions, but often materials need to be concentrated this.

Cells and Their Environment Objectives: 1. Relate concentration gradients, diffusion, and equilibrium. 2.Describe the importance of ion channels in passive.
Movement through the cell: Molecules have to move around the cell to do their jobs. Sometimes they go into, or out of an organelle. Our cells use Diffusion.
Unit 1: Homeostasis & the Cell Homeostasis The body’s ability to maintain a stable internal (inside) environment, while the external (outside) environment.
Cell Boundaries 7-3. Cell Membrane Cell membrane = – controls what enters and leaves the cell – provides protection and support – Receives chemical signals.
Cell Transport 7-3 Pgs. 182-189. Cell Membrane Cell membrane regulates what leaves and enters the cell. It is a lipid bilayer with proteins embedded in.
