Document Summary
Primary function of enzymes is to accelerate rates or velocities of reaction: allosteric enzymes allows for efficient integration of metabolism, catalysts and info sensors. Sense signals in environment that allow them to regulate rates of reaction to meet metabolic needs of cell and facilitate efficient coordination of various metabolic pathways. Kinetics study of rates of chemical reactions. Enzyme kinetics rates of enzyme-catalyzed reactions. Velocity of reaction quantity of reactant a that disappears in specified unit of time (t: equal to velocity of appearance of product (or quantity of p that appears in specific unit of time) K rate constant, velocity of reaction directly related to [a] by proportionality constant (k) second) 1 st order reaction velocity directly proportional to reactant concentration (unit is per. 2 nd order reaction biochemical reactions that include 2 reactants (unit is per mole per. V = k[a] 2 or v = k[a][b] Zero-order reaction rate is independent of [reactant] second)
