Enzymes

Start with enzyme action

The Enzymes page brings together resources on how enzymes work and what affects their activity. A useful starting point is the mind map that outlines activation energy and how enzymes combine with reactants. The Enzymes and Energy mind map also connects enzymes with energy and its transformation. These resources offer places to organize the ideas before moving into more detailed questions.

Explore cofactors and inhibition

The unfinished slide set on cofactors, enzymes and prosthetic groups introduces cofactors as non-protein components that help enzymes function. It also describes coenzymes as organic cofactors. For inhibition, the Enzymes 2 mind map covers competitive and non-competitive inhibition, including competition for an enzyme's active site. Study these after the introductory maps to focus on particular aspects of enzyme action.

Practice rates and key terms

The Enzyme kinetics flashcards ask about the Michaelis-Menten equation and maximal reaction velocity. Other listed resources cover the effects of temperature and substrate concentration on enzyme-catalyzed reactions. After studying a map, use a flashcard deck to recall its terms and questions, then return to the map to check ideas that need more attention.

Use the quiz alongside the maps

The listed Enzymes quiz offers another way to practice. It can follow your first pass through the maps and flashcards, or help you choose what to study again. This topic is part of the Biochemistry unit in Chemistry, so the page also provides a focused place to study enzymes within that unit. Pick a resource and work through it at your own pace.
