What happens to the volume of solids liquids and gases when they cool? Solids- stays the same Liquids- stays the same Gases- decreases You can use the formula PV/T=P2V2/T2 P=initial pressure V=initial volume T=initial temp P2=final â¦pressure V2=final volume T2=final temp (MORE) 2 people found this useful.
Active transport requires the use of energy or ATP. In active transport you go against the concentration gradient, and for that ATP is used. Their are two types of active transport. Primary and secondary active transports and both use ATP, thou secondary uses less ATP than primary. Passive transport does not use any ATP.
Best Answer: There are two ways that the molecules move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane.Passive transport does not require such an energy expenditure, and occurs spontaneously. The principle means of passive transport is diffusion.ctive transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane. Passive transport does not require such an energy expenditure, and occurs spontaneously.
