| active transport | movement of substances through a cell membrane using the cell’s energy |
| diffusion | movement from an area of higher concentration to an area of lower concentration |
| endocytosis | process during which a cell takes in a substance by surrounding it with the cell membrane |
| exocytosis | process during which a cell’s vesicles release their contents outside the cell |
| facilitated diffusion | when molecules pass through a cell membrane using transport proteins |
| osmosis | diffusion of water molecules only through a membrane |
| passive transport | movement of substances through a cell membrane without using energy |
| cellular respiration | series of chemical reactions that convert energy in food molecules into ATP |
| fermentation | reaction used to obtain energy from food when oxygen levels are low |
| glycolysis | process by which glucose is broken down |
| photosynthesis | series of reactions that convert light energy, water, and CO2 into glucose and give off oxygen |
