Chapter 7
Cells and Their Environment Objectives: 1. Relate concentration gradients, diffusion, and equilibrium. 2.Describe the importance of ion channels in passive.
Section 4-1 1 way cells maintain homeostasis is controlling movement of substances across cell membrane Cells must use energy to transport some substances.
AP Bio Chap 7 Osmosis and Diffusion. So, how does a membrane regulates what goes in and out? Depends on: 1)Lipid solubility - Hydrophobic molecules, such.
Membrane Transport. Solute Movement across Lipid Bilayers Materials can move across the cell membrane in different ways. – Passive transport does not.
Biology: 4.1 Cells and Their Environment Passive Transport in Cells.
NOTES: CH 7 part 2 - Transport Across the Cell Membrane (7.3-7.5)
