Active transport is a process that is required to move ... Nettet8. jun. 2024 · To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from adenosine triphosphate (ATP) generated through the cell’s metabolism. Active transport mechanisms, collectively called pumps, work against electrochemical gradients. Small substances constantly pass …
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 nor… NettetGCSE Biology help. I know this is really nit-picky, but would you say “during active transport, particles move AGAINST the concentration gradient” or “during active transport, particles move UP the concentration gradient”. Against. 'Up' could refer to moving upwards, and just comes off as vague.
