Unlike passive transport active transport requires the cell to use what?
Specialized transmembrane proteins recognize the substance and allow it to move across the membrane when it otherwise would not either because the phospholipid bilayer of the membrane is impermeable to the substance moved or because the substance is moved against the direction of its concentration gradient. There are two forms of active transport primary active transport and secondary active transport. In primary active transport the proteins involved are pumps that normally use chemical energy in the fo…

Passive transport - Wikipedia
Facilitated diffusion also called carrier-mediated osmosis is the movement of molecules across the cell membrane via special transport proteins that are embedded in the plasma membrane by actively taking up or excluding ions. Active transport of protons by H ATPases alters membrane potential allowing for facilitated passive transport of particular ions such as potassium down their charge gradient through high affinity transporters and channels.
Method of glucose uptake differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of glucose.The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP known as primary active ...
Exocytosis (/ ˌ ɛ k s oʊ s aɪ ˈ t oʊ s ɪ s /) is a form of active transport and bulk transport in which a cell transports molecules (e.g. neurotransmitters and proteins) out of the cell (exo-+ cytosis) by secreting them through an energy-dependent process. Exocytosis and its counterpart endocytosis are used by all cells because most chemical sub...
