These structures make up the cell membrane and have a polar head and 2 nonpolar tails:

• proteins

• phospholipids

• antibodies

• nucleotides

Movement of any substance from an area of high concentration to low concentration is called _____.

• diffusion

• osmosis

• active transport

• exocytosis

Passive transport does not require energy (ATP) while active transport does.

• True

• False

A type of cellular transport is shown.

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

Match the following vocabulary terms and definitions.

• Hypertonic

• Same concentration; the solution and cell have equal concentration of solutes (particles), so water moves equally between the cell and solution.

• Hypotonic

• Low concentration; the solution has less solutes than the cell, causing water to move into the cell and out of the solution.

• Isotonic

• High concentration; the solution has more solutes than the cell, causing water to move out of the cell and into the solution.

​ (a)   brings glucose into cells.

• Insulin

• Glucagon

• Glycogen
