reactions that occur spontaneously and release free energy are called _ reactions | exergonic |
Protein catalysts that speed up the various metabolic biological reaction in an organism are called | enzymes |
Enzymes have specific _ with which they interact | substrates |
the chief energy currency of all cells is a molecule called | ATP |
Reactions that do not proceed spontaneously because they require energy from an outside source are called | endergonic |
enzymes catalyze chemical reactions by lowering the | activation energy |
RNA molecules that have been recently reported to act also as enzymes are given the name | ribozymes |
in an enzyme catalyzed reaction the reactant is called the | substrate |
