How is energy expanded in active transport
Katarina [22]
<h3><u>Expansion of energy in active transport:</u></h3>
  • Active transport is a transport process that involves movement of molecules between regions through a membrane against the concentration gradient.
  • It is homeostatic process which means it’s a biological process in which functions of the body are regulated to achieve internal balance.
  • Active transport uses metabolic energy ATP to transport molecules across a membrane.
  • Generally, metal ions are transported across cell membrane by active transport.
  • Metal ions are transported with the help of ion pumps and are distributed through the body.
