Enzyme Activation Energy definitions Flashcards

A biological catalyst that accelerates chemical reactions by reducing the activation energy required, without being consumed in the process.

The minimum energy required for reactants to reach the transition state and initiate a chemical reaction, influencing the reaction rate.

A temporary, high-energy configuration of reactants during a chemical reaction, representing the peak of the energy barrier that must be overcome for the reaction to proceed.

Substances that undergo change during a chemical reaction, starting with higher energy before transforming into products.

Substances formed as a result of a chemical reaction, having lower free energy than the reactants in exergonic reactions.

A chemical reaction where the products have lower free energy than the reactants, releasing energy and occurring spontaneously.

A chemical reaction that absorbs energy from its surroundings, resulting in products with higher free energy than the reactants.

The energy available to do work in a system, determining the direction and spontaneity of biochemical reactions.

The progression of a chemical reaction over time, typically depicted as a graph showing changes in free energy from reactants to products, including the transition state.

A process where reactants are transformed into products, involving the breaking and forming of chemical bonds, and requiring an initial energy input to proceed.

The minimum energy required for reactants to reach the transition state and initiate a chemical reaction, influencing the reaction rate.

A measure of the average kinetic energy of particles in a substance, influencing reaction rates and enzyme activity.
