Enzymes and Their Properties

*Note: THIS IS A STUDY GUIDE!! I did not write it to be considered as an essay, rather to assist any confused Bio students, help out with homework, or any other purpose that people see fit. Please do not critique my format, it's not an essay! Enzymes are proteins that acts as catalysts in organisms. A catalyst is a substance that speeds up reactions without the addition of heat; decreases the activation energy needed for …showed first 75 words of 335 total…

Coenzymes- organic cofactors, some vitamins. Irreversible Inhibitors- bond to active site and permanently cripple the enzyme. Competitive Inhibitors- substances that prevent an enzyme from functioning by mimicking substrate, can be overcome by adding more substrate. Noncompetitive Inhibitor- substance that prevents an enzyme from functioning, attach at some other place and distort active site so substrate cannot attach.
