Cell transport

What process occurs that moves molecules like oxygen from an area of high concentration to an area of low concentration

• Active Transport

• Diffusion

• Facillitated diffusion

• Phagocytosis

• Osmosis

Carbon dioxide and oxygen are able to cross through what part of the cell?

• Plasma Membrane

• Cell Wall

• Cholesterol

• Carrier Protein

When molecules like Oxygen and Carbon Dioxide move from areas of high concentration to areas of low concentration, we call this a concentration gradient .

• False

• True

Facilitated diffusion requires energy and the use of a protein to get large molecules like glucose across the membrane.

• True

• False

Osmosis is the movement of water from areas of high concentration to areas of low concentration.

• True

• False

When a cell is put into a hypertonic solution, the cell _______ water.

• loses

• gains

• neither loses or gains

When a cell begins to gain water and swell, what type of solution was the cell placed in?

• hypertonic

• isotonic

• Hypotonic

When a cell is isotonic, the body is not in homeostasis and would be trying to balance the water.

• False

• True

For simple diffusion, facilitated diffusion, osmosis, and filtration to occur, energy is required.

• False

• True

What type of transport is the sodium-potassium pump?

• Passive Transport

• Active Transport

• Osmosis

• Facillitated Diffusion
