Understanding Energy in Biological Reactions

These flashcards summarize key concepts related to energy consumption and biological reactions, including definitions of terms such as Activation Energy, Delta G, and more.

Activation Energy

The minimum amount of energy required for a chemical reaction to occur.

Delta G

The change in free energy during a reaction, indicating whether the reaction is spontaneous or requires energy input.

Transition State

A temporary state during a chemical reaction in which the reactants are in an unstable configuration, often requiring energy to attain.

Coupled Reactions

Reactions that occur together where the energy from one reaction is used to drive another reaction.

Energy Barrier

The obstacle represented by activation energy that must be overcome for a reaction to proceed.

ATP Production

The process by which cells generate adenosine triphosphate (ATP), producing millions of ATP molecules every second.
