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.
The other process is referred to as active transport because it requires the cell to expend chemical energy, typically adenosine triphosphate, commonly called ATP. Active transport occurs when a solute must pass through the cell membrane against its concentration gradient.A good analogy is that this is like pushing the water that fell over a waterfall, back up the river to the falls above. It takes a lot of energy for the cell to do this.he other process is referred to as active transport because it requires the cell to expend chemical energy, typically adenosine triphosphate, commonly called ATP.
