Class 16 Opener 10/22/15What is the difference between active and passive transport when discussing cellular membranes? Active transport requires energy (ATP) and passive transport does not.Image A is an example of ? Image A is an example of active transport.How is diffusion different than osmosis? Osmosis is a specialized form of diffusion. Diffusion may or may not be a form of osmosis. Specifically osmosis is the diffusion of water across a semipermeable membrane.

Opener Oct. 26What controls the molecular movement in and out of a cell? The cell membrane controls the movement of molecules in and out of a cell.What does the drawing in Image A represents? Image A is of a cell membrane.What does the animation in Image B represent? The animation represents diffusion.Image BImage A

Opener Oct. 26Lab: soap bubble What did the bubble represent? It represented a cell membrane.Explain how the skin of the bubble differs from a cell membrane. The soap bubble non-polar tails face in the opposite direction of a cell membrane tails. Cell membrane non-polar tails face each other while the polar heads face outward from each other.

Opener Oct. 26What does Image A represent? Image A represents a Phospholipid MoleculeHow many layer(s) make-up cell membranes? Two layers of phospholipids make up a cell membrane.Describe the differences between active and passive transport. Active transport uses ATP (energy) to move substances through membrane and passive does not.

Cell Membrane Activity

Slide#

Lipid soluble molecules are transported through the cell membranes more easily than water soluble moleculesSmall molecules are transported through the membrane more easily than large moleculesThe higher the charge on the molecule, the harder it is for it to be transported through the membrane
