Kinetics
Kinetics (with an "s" at the end) refers to the rate of change in a biochemical (or other) reaction, the study of reaction rates. Kinetics is a noun. It is distinct from "kinetic" (an adjective) meaning with movement. The opposite of kinetic is akinetic meaning without movement. In neurology, kinetic and akinetic serve to denote the presence or absence of movement. Kinetic comes from the Greek word "kinesis" for motion. The term "akinetic" is put together from the prefix "a-" meaning "without" + "kinesis" = without motion. Kinesis is verbatim from the Greek "kinesis."

- enzyme k. the study of the rates, and alterations in those rates, of enzyme-catalyzed reactions; includes the reactions catalyzed by synzymes, abzymes, and ribozymes.

ki·net·ics (kĭ-netґiks) [Gr. kinētikos of or for putting in motion] the branch of dynamics that pertains to the turnover, or rate of change, of a specific factor (e.g., erythrocytes—erythrokinetics, leukocytes—leukokinetics, or iron—ferrokinetics), commonly expressed as units of amount per unit time.
