active transport âœâ€Ã¢Å“â€movement of molecules across a cell membrane from a region of lower
concentration to a region of higher concentration—against the concentration gradient. Active
transport requires cellular energy to achieve this movement.
passive transport âœâ€Ã¢Å“â€Requires NO energy, movement of molecules from high to low
concentration, moves with the concentration gradient
covalent bond âœâ€Ã¢Å“â€A chemical bond that involves sharing a pair of electrons between atoms in a
molecule
ionic bond âœâ€Ã¢Å“â€Linkage formed from the electrostatic attraction between oppositely charged ions
in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom
are transferred permanently to another atom.
allosteric bond âœâ€Ã¢Å“â€The regulation of an enzyme by binding an effector molecule at a site other
than the enzyme's active site.
Substrate âœâ€Ã¢Å“â€reactant of an enzyme-catalyzed reaction
substrate-enzyme complex âœâ€Ã¢Å“â€The substrate connects to the enzyme to perform chemical
reactions. It connects to the enzyme at the active site.
substrate enzyme inhibition âœâ€Ã¢Å“â€the substrate or product of an enzyme reaction inhibit the
enzyme's activity.
Carbohydrates âœâ€Ã¢Å“â€Are sugar molecules- our body breaks down carbohydrates into glucose.
Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.
