AP Bio-Cell TRansport

To provide energy for the cell

To control the movement of substances in and out of the cell

To produce proteins

To store genetic information

It controls the movement of substances in and out of the cell.

It produces energy for the cell.

It stores genetic information.

It synthesizes proteins.

A concentration gradient

Energy from ATP

Carrier proteins only

Active pumping mechanisms

Oxygen (O2)

Carbon Dioxide (CO2)

Glucose

Sodium ions (Na+)

Each channel protein allows only certain molecules or ions to pass through.

Channel proteins allow all molecules to pass freely.

Channel proteins only transport water molecules.

Channel proteins require energy to function.

It moves sodium ions out of the cell.

It moves potassium ions into the cell.

It requires ATP to function.

It transports glucose across the membrane.

Transport multiple molecules simultaneously

Break down large molecules

Produce ATP

Allow only water to pass through

Endocytosis

Exocytosis

Osmosis

Diffusion

Hypertonic solutions have more solute and less solvent.

Hypotonic solutions have less solute and more solvent.

Isotonic solutions have equal concentrations of solute and solvent.

The solvent in these comparisons is always water.

It becomes plasmolyzed

It becomes flaccid

It becomes turgid

It bursts

It measures how likely water will move in or out of a solution.

It measures the concentration of solutes in a solution.

It measures the temperature of a solution.

It measures the volume of water in a cell.

A: Sucrose, 2M, 298K

B: NaCl, 1M, 290K

C: Glucose, 1M, 300K

All will gain the same amount of water
