Characterize each term or phrase as pertaining to simple or facilitated diffusion. Simple diffusion Facilitated diffusion Answer Bank requires an input of free energy lipophilic molecules directly through membrane via channels polar molecules Na+

Sort the descriptions into properties that describe either saturated phospholipids or unsaturated phospholipids. Saturated phospholipids Saturated and unsaturated phospholipids Unsaturated phospholipids Answer Bank have no double bonds in the fatty acid carbon chains have straight fatty acid tails have at least one double bond in the fatty acid tails have bent fatty acid tails are built upon a glycerol backbone make the membrane somewhat rigid at low temperatures allow the membrane to remain fluid and flexible at low temperatures fatty acid tails pack tightly together maintain some space between adjacent phospholipids

Place the events of an action potential in order, starting and ending with a cell at its resting membrane potential. Cell starts at its resting membrane potential. Cell returns to its resting membrane potential. Answer Bank K+ channels fully open, and Na+ channels are inactivated. K* rushes out of the cell, causing repolarization. K+ channels close slowly, resulting in hyperpolarization. Na+ channel gates reset. Fast Na+ and slow K+ channels are activated. Na rushes into the cell, causing membrane depolarization. Ligand activation of the acetylcholine receptor depolarizes the membrane.
