Bio Vocab Flashcards

Energy

The ability to do work.

Potential Energy

Energy stored in an object due to its position or state.

Kinetic Energy

Energy of an object in motion.

Chemical Energy

Energy contained in the chemical bonds of organic molecules, such as food.

Mechanical Energy

A type of kinetic energy converted from chemical energy.

Entropy

Relative amount of disorganization.

Exergonic Reactions

Chemical reactions that release energy, often in the form of heat, making them spontaneous.

Endergonic Reactions

Chemical reactions that require an input of energy, resulting in products with a higher energy level than the reactants.

ATP

Adenosine triphosphate, the energy currency for cells used to transfer energy within cells.

ADP

Adenosine diphosphate, a molecule formed when ATP loses a phosphate group, crucial for cellular energy transfer.

Metabolism

The set of life-sustaining chemical reactions in organisms, including catabolic and anabolic pathways.

Catabolism

The breakdown of complex molecules into simpler ones, releasing energy.

Anabolism

The building up (synthesis) of molecules.

Free Energy

Energy that is available to do work.
