passive transport | the movement of substances through the cell membrane without using the cells energy high to low no atp |
active transport | the movement of substances through the cell membrane only by using the cells energy low to high atp |
diffusion | movement of substances from high to low concentration |
osmosis | diffusion of water molecules only through the membrane |
facilitated diffusion | when molecules pass through a cell membrane using special proteins called transport proteins |
respiration | a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP plant and animal mitochondria |
photosynthesis | a series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen plant chloroplast |
p formula | water+carbon dioxide+sun>oxygen+glucose or sugar |
r formula | oxygen+glucose>water+carbon dioxide+energy |
