UNIT 3 - Enzymes Flashcards
What are the properties of enzymes?
Highly substrate specific, globular proteins, soluble, spherical, tertiary structure, fast acting. Affected by temp + pH.
What do enzymes have which allows them to catalyse reactions?
Highly substrate specific active site (substrate receptor site) which is complementary to a particular substrate.
When enzymes react and combine with the substrate, what do they form? What happens when the reaction is over?
Enzyme/substrate complex. Products are released and enzyme is left unchanged.
Enzymes are fast acting, what does this mean?
High turnover number. Convert many molecules of substrate per unit time.
What can enzymes build up and break down and how?
Molecules (carbs, proteins, lipids) hydrolysed by digestive enzymes. (starch + glycogen) built up from monomers for storage.
What type of protein are most enzymes? e.g. fibrous/conjugated etc.
Conjugated protein.
