Movement of particles from one side of a cellular membrane to another.
Tendency of particles to distribute themselves evenly across a membrane.
Transfer of molecules in response to excess solute relative to a solution.
Ability to maintain and regulate stable internal conditions of the cell.
Glucose and ATP
Oxygen and Glucose
Water and Oxygen
ADP and NADP-
Passive transport requires energy to move molecules up a concentration gradient, active does not.
Passive transport can only move specific particles across a membrane, active can move any particle.
Active transport requires energy to move molecules up a concentration gradient, passive does not require energy (moves down gradient)
Active transport moves molecules in animal cells, passive transport moves molecules in plants.
Blood vessels transport glucose to cells
CO2 waste is eliminated during respiration
