Cell Transport Review

This type of solution has more salt/solute than a human cell?

• hypotonic

• hypertonic

• isotonic

• technotronic

Active transport means items cross the cell membrane from L-->H using

• passive diffusion

• facilitated diffusion

• energy

• water

The sodium/potassium pump is an active transport protein pump that moves this many sodium ions out of the cell each time?

• 1

• 2

• 3

• 4

Exocytosis is the process of moving substances out of a cell. What type of transport is this?

• active transport

• passive transport

• osmosis

• diffusion

Ion channels, pumps, receptors, enzymes all exist within the cell membrane. These are all made of

• lipids

• carbohydrates

• nucleic acids

• protein

When water moves from an area of high percentage of water to an area of lower percentage of water.

• osmosis

• active transport

• gas diffusion

• endocytosis

The cell membrane is made of two layers of phospholipids. The phosphate heads face outside and the lipid tails face each other on the inside of the membrane. What part of cell membrane is water hating (hydrophobic)?

• phosphate heads

• the outside layers

• the cytoplasm

• the lipid tails

What solution will cause a red blood cell to burst?

• hypertonic (salty)

• hypotonic (pure water)

• isotonic

• dehydration

Movement from L-->H, use of ATP energy, exiting substances from a cell, pulling substance into a cell, all require ATP. This is called

• active transport

• passive transport

• osmosis

• facilitated diffusion

Gasses are so small that they can move easily from H-->L across the cell membrane. Gasses use this type of movment?

• endocytosis

• osmosis

• active transport

• simple diffusion
