What is the cytoplasm made of?

Proteins that are embedded in the cell membrane.

AKA: transmembrane

Proteins that are anchored to either the inside or outside of the membrane.

A membrane protein that combines with and “reads” messengers from other cells like hormones.

A membrane protein that is constantly open and allows solutes to pass into and out of the cell.

A membrane protein that opens and closes. It only allows solutes through at certain times.

Arm structures on white blood cells that grab bacteria and bring them toward the cell to be destroyed.

The process by which a cell takes something into itself.

Ex: White blood cells engulfing bacteria.

What are the three types of passive transport?

What are the three types of active transport?

Passive transport where particles move from areas of high concentration to low concentration.

Diffusion of water down its concentration gradient.

Membrane protein that increases the speed of osmosis. (Diffusion of water from an area of high concentration to an area of low concentration.)

The ability of a solution (like blood) to control the amount of water that goes into or out of the cell.

Ex: hypotonic, isotonic, hypertonic

Tonicity level when there is just the right amount of particles (solutes) within a cell and no water moves in or out.

Tonicity level when there are too many particles (solutes) with a cell and water is forced out of the cell.

Tonicity level when there are too few particles (solutes) within the cell and too much water moves into the cell.

Type of active or passive transport where a membrane protein moves specific particle(s) across the membrane. Could also be considered facilitated diffusion.

What are the three kinds of carriers that can perform carrier mediated transport?

Carrier mediated transporter that moves one type of molecule in one direction.

Carrier mediated transporter that moves multiple types of molecules in one direction.

Carrier mediated transporter that moves multiple molecules in different directions.

Type of transport that uses ATP to move molecules up or against their concentration gradient. Ex: potassium pump

Type of active transport that is used to move large particles or many particles in or out of the cell using vesicles.

Endocytosis and phagocytosis are the same thing. True or False?

When a cell uses vesicles to move molecules out of the cell.
