What is it called when an input of energy is required to move materials through a cell membrane? Active Transport
What is it called when materials through a cell membrane WITHOUT the input of energy? Passive Transport
What is a type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them? Diffusion
When molecules of one substance are spread evenly throughout another substance it is called_____________. This is reached when diffusion stops. Equilibrium
When cells do not have enough oxygen for respiration, they use this process to release some of the energy stored in glucose molecules. Fermentation
