cell transport

cousins middle school, 7th grade, cell transport

active transport the movement of substances across a cell membrane that uses ENERGY- can move LARGE particles (such as in endocytosis and exocytosis) OR move against equilibrium
passive transport this movement of a substance across a cell membrane that uses NO ENERGY- moves small particles- moves things from areas of high concentration to areas of less concentration until equilibrium is acheived
endocytosis a process in which a cell surrounds a particle and brings it in using energy- creates a vesicle around it
exocytosis a process in which a cell surrounds a particle and pushes it out using energy- creates a vesicle around it
diffusion movement of particles across a membrane from high concentration to lower concentration until equal= any substance other than water
osmosis same as diffusion but only with water
photosynthesis process by which plants (and some algae and bacteria) make glucose from the sun- happens in chloroplasts
cellular respiration process by which cells break down sugar for energy happens in the mitochondria, uses oxygen- water is a waste product
fermentation process by which the cell breaks down sugar for energy, happens in the cytoplasm, does not use oxygen- lactic acid and alcohol can be waste products
homeostasis the maintenance of a constant internal state in a changing environment- a cell's happy place
semipermeable membrane a barrier that lets some things go through, but not everything
glucose sugar
