Basic Biochemistry

The Biology Project: Biochemistry

This website allows you to take tutorials and then test your knowledge. Learn about enzymes, metabolism, photosynthesis, plus more. Also includes other online resources.

Enzymes

CHAPTER 7: Metabolism and Biochemistry

Learn about enzymes: how they work, the lock and key model, substrate specificity, cofactors, enzyme inhibitors, plus more.

Energy and Enzymes

Written in note form, this site looks at energetic systems, enzymes and enzyme activity.

Energy, Enzymes, and Catalysis Problem Set

Part of the Biology Project website, progress through the tutorial and learn more about enzymes.

Enzymes

An introduction to enzymes and their role as a catalyst. Includes competitive inhibition, enzyme cofactors, a closer look at factors affecting enzyme action, and regulation of enzyme activity.

Reactions and Enzymes

This website introduces us to endergonic and exergonic reactions, oxidation and reduction, catabolism and anabolism, enzymes and inhibition.

Cellular Energetics

Calvin Cycle

Part of the AP biology Training page, this is an animated diagram displaying in several steps the Calvin Cycle.

Cellular Respiration

A look at the structure of mitochondria, and the process involved in cellular respiration.

Electron Transport Chain

Part of the AP biology Training page, this is an animated diagram displaying in several steps the Electron transport Chain.

Krebs Cycle

This is an animated diagram displaying in several steps the Krebs cycle starting with the condensation of Acetyl CoA with Oxaloacetate.

Learning about Photosynthesis

Hosted by Arizona State University, this site provides a list of other web sites about photosynthesis and is aimed at school students.

TCA Cycle

Part of the AP biology Training page, this is an animated diagram displaying in several steps the Tricarboxylic cycle.
