Lecture #2 (REDO): Biomolecules & Metabolism

Large, complex molecules essential for life.

Oxygen

Hydrogen

Carbon

Nitrogen

Nucleic Acids

Lipids

Proteins

Carbohydrates

Metabolism is the chemical reactions that occur within a living organism.

Monomers are larger structures, while polymers are smaller units. Polymers combine to form monomers.

Catabolism and anabolism

Monomers and polymers

A catabolic reaction builds larger molecules from smaller ones, consuming energy via a hydrolysis reaction.

A catabolic reaction happens via a hydrolysis reaction, breaking down larger molecules into smaller ones, releasing energy.

A catabolic reaction is a process that does not involve any energy changes, primarily condensation reactions.

Anabolic reactions break down complex molecules into simpler ones via condensation reactions

Anabolic reactions occur without the use of energy via hydrolysis .

Anabolic reactions are solely responsible for energy production through the use of condensation reactions.

Anabolic reactions are accomplished by using energy and a condensation reaction to form molecules from simpler ones.
