Front

Chemiosmosis

Back

A process that uses a hydrogen ion gradient to drive the synthesis of ATP.

Front

Electron Transport Chain

Back

A series of membrane-embedded electron carriers that create a hydrogen ion gradient.

Front

Hydrogen Bond

Back

A relatively weak bond formed between a partially positively charged hydrogen atom and a negatively charged atom, such as oxygen.

Front

Enzyme

Back

A biological molecule that acts as a catalyst, lowering the activation energy needed for a reaction.

Front

Hydrolysis

Back

The process of adding water to split a large molecule into smaller pieces (polymer to monomer).

Front

Dehydration Synthesis

Back

The process of joining two molecules together by removing water.

Front

ATP (Adenosine Triphosphate)

Back

The primary energy carrier in cells, used to power various biological processes.

Front

Photosynthesis

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

Cellular Respiration

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

Mitosis

Back

A type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell.
