Introduction to Energy and Chemical Reactions in Physiology

Vocabulary flashcards reviewing concepts of energy types, endergonic and exergonic reactions, ATP, and energy change calculations based on the lecture.

Kinetic energy

The energy associated with movement.

Potential energy

Stored energy that has the potential to do work.

Synthesis reaction

A reaction in which bonds are formed, requiring the addition of energy to proceed.

Decomposition reaction

A reaction in which bonds are broken, releasing energy during the reaction.

Exergonic reaction

A chemical reaction that releases energy during its course, such as the decomposition of ATP and water into ADP plus a phosphate.

Endergonic reaction

A chemical reaction that requires energy to be added to form bonds, such as combining amino acids to form a protein.

ATP

The cell battery, produced from ADP and a phosphate group, which is continuously made and broken down to release energy for cellular work.

Delta ($\Delta$)

A symbol representing change.

Delta E ($\Delta E$)

The change in energy, which equals the energy of the products minus the energy of the reactants.
