Which process requires energy- passive or active transport?
Answer:
Active transport requires energy. Active transport is generally needed for larger molecules, such as in endocytosis, and moving ions against an electrical or concentration gradient.
Active transport takes more energy. Sometimes things need to be pumped across a membrane depending on the concentration of the material on the other side.
Active transport. The cells spends energy to move a molecule against a gradient. An example of passive transport is osmosis.
In Active Transport, cells use energy to move particles from areas of low concentration to areas of high concentration.
Active Transport is the opposite of diffusion.
Think of the words used:
Active
reminds me of someone running, or doing some physical activity... so I remember that Active is Energetic!
Passive
means uninvolved. no energy. it actually means opposite of active. obviously this one is not going to use energy.
