4 - enzymes

Question 1

what are enzymes

Answer 1

they are biological catalysts in the body that help speed up reactions

Question 2

what is lock and key?

Answer 2

gcse stuff icl

basically the enzyme has an active site made only for the one specific substrate. this means that if the active site denatures in any way the enzyme will not work in the desired way

Question 3

what is induced-fit?

Answer 3

induced fit is like lock and key, it’s just that the active site is more flexible in a sense and kinda squishes to the substate

Question 4

competitive inhibition

Answer 4

competitive inhubititoon is just normal substrates competing for an active site.

Question 5

non-competitive inhibitors

Answer 5

they don’t compete with other substrates and just bind to the allosteric site, which then changes the active site

Question 6

Define cofactor and coenzyme

Answer 6

​Cofactor: Inorganicsubstaces that fit to the active site of an enzyme toactivate the enzyme

Coenzyme:Large organic substances that take part in an enzyme controlled reaction
