Activetransport requires cellular energy to achieve this movement.passive transport✔✔Requires NO energy, movement of molecules from high to lowconcentration, moves with the concentration gradientcovalent bond✔✔A chemical bond that involves sharing a pair of electrons between atoms in amoleculeionic bond✔✔Linkage formed from the electrostatic attraction between oppositely charged ionsina chemical compound. Such a bond forms when the valence (outermost) electrons of one atomare transferred permanently to another atom.allosteric bond✔✔The regulation of an enzyme by binding an effector molecule at a site otherthan the enzyme's activesite.Substrate✔✔reactant of an enzyme-catalyzed reactionsubstrate-enzyme complex✔✔The substrate connects to the enzyme to perform chemicalreactions. It connects to the enzyme at the active site.substrate enzyme inhibition✔✔the substrate or product of an enzyme reaction inhibit theenzyme's activity.Carbohydrates✔✔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.Preview Mode
