Hi, was wondering if anyone would be able to help me out on the following questions regarding enzymes, i have my SAC coming up soon
1. “enzymes are ‘reversible’ and can work in either direction: substrate—> product or product—> substrate” BUT product is never turned into substrate though? even in a catabolic reaction large substrate turned into smaller products
2. is it ok to say ‘active site is a region of the protein molecules which provides a site of attachment for SUBSTRATES’ (rather than REACTANTS)
3. does the concept of ‘enzyme specificity’ apply to the induced fit model? if so, how do you explain this as the shape of the active site isn’t exactly complementary to the shape of the substrate
4. how are all chemical reactions energy dependent/require input of energy? catabolic reactions release energy…
5. are enzymes considered denatured at very low temperatures?
6. is there a difference between rate of enzyme activity/rate of reaction? ex. in the sentence: as enzyme concentration increases, rate of enzyme activity also increases
7. non-competitive inhibitors. Do they prevent binding or just reduce ability to bind?
8. both competitive and non-competitive inhibitors are reversible right?
9. cofactors include coenzymes? or are they separate? what is the extent to which we should know about these
