www.ncert.nic.in11.1.3 Active Transport Active transport uses energy to pump molecules against a concentration gradient. Active transport is carried out by membrane-proteins. Hence different proteins in the membrane play a major role in both active as well as passive transport. Pumps are proteins that use energy to carry substances across the cell membrane.

www.sd27j.orgActive Transport Across the Cell Membrane Active transport is the movement of solutes against a gradient and requires the expenditure of energy, usually in the form of ATP. Active transport is achieved through one of these two mechanisms: Protein Pumps • Transport proteins in the plasma membrane transfer solutes such as small ions (Na+, K+ ...

Active Cell Balancing in Battery Packs
www.nxp.comThe active balancing method is base d on the active transport of the energy among the cells. This balancing method does not depend on the chemical characteristics of the cells, and can be used for most types of modern batteries. There ar e several types of active balancing methods based on th e type of energy transfer.
