Biology 120 Notes (Part 9) Phospholipids, Plasma Membrane, Diffusion, and Osmosis

________ describes how the plasma membrane engulfs a smaller cell or food particle.

________ are attached to proteins or phospholipids, and they function as cellular "fingerprints ..

________ is the net movement of molecules down a concentration gradient.

________ occurs in plant cells.

________ consist of one glycerol molecule linked to two fatty acids and a modified phosphate group.

Facilitated diffusion is a(n) ________ involving transmembrane proteins.

________ make the membrane less permeable (increased hydrophobic reactions .)

________ is the diffusion of water across a selectively permeable membrane.

________ is the movement of large particles across the plasma membrane using vesicles.

________ are a combo of two gradients.

Adding ________ to membranes increases the density of the hydrophobic section and it reduces membrane permeability.

________ describes a specific form of pinocytosis using receptor proteins and a coated pit.

________ moves substances against their gradient and requires an input of energy (ATP .)

________ describes how vesicles form around a liquid or very small particles.

________ decreases as the temperature drops.

________ describe how the amount of solute and water are equal on both sides of the membrane.

________ is a type of passive transport.

________ also tend to form a phospholipids bilayer.

________ decreases as temperature drops.

diffusion, facilitated diffusion through transports of carriers, and active transport (this mechanism requires energy for transport.)

integral and peripheral

exocytosis and endocytosis

diffusion, facilitated diffusion through transports of carriers, and active transport (this mechanism requires energy for transport.)

integral and peripheral.

the number of double bonds in phospholipid tails, length of the tails, the number of cholesterol molecules in the membranes, and the temperatures.
