How does osmosis work? → The diffusion of water across a selectively permeable membrane
What is the energy of activation? → The amount of energy the reactants must absorb to become active and start a chemical reaction/get over the energy barrier
How is a phospholipid structured → A solution whose pH is lower than that of the cells, cell gains water, pops
What is osmosis? → The diffusion of water across a selectively permeable membrane
How are enzymes like assembly lines? → fluid mosaic of phospholipids and proteins
