BIOL 1907 Module 2

Anabolic

metabolic pathway where small molecules assemble into large ones requiring energy.

Catabolic

metabolic pathway where large molecules break down into small ones, releasing energy.

Metabolism

the chemical reactions that occur inside cells, including those that use/release energy.

REDOX reactions

chemical reactions involving the exchange of electrons.

Autotrophs

organisms that create their own energy from inorganic compounds.

Heterotrophs

organisms acquire energy by consuming preformed organic matter.

Adenosine triphosphate (ATP)

molecule that functions as the primary energy currency for cellular processes. Functions like a battery

Adenosine diphosphate (ADP)

discharged form of ATP.
