Name the type of bond that joins amino acids together.
peptide bond
1 of 8
State the type of reaction involved in joining amino acids together
condensation reaction
2 of 8
List 4 different components that make up an amino acid.
amino group, carboxyl group, hydrogen atom, R group
3 of 8
Define a catalyst
a substance that alters the rate of a chemical reaction without undergoing permanent change
4 of 8
Explain why enzymes are effective in tiny quantities
they are not used up in the reaction and so can be used repeatedly
5 of 8
Explain why enzymes function less well at lower temperatures
to function, enzymes must physically collide with their substrate. Lower temps decrease the kinetic energy of both enzyme and substrate molecules, which then move around less quickly. They hence collide less often and therefore react less frequently.
6 of 8
Explain how high temperatures may completely prevent enzymes from functioning
The heat causes hydrogen and other bonds in the enzyme molecule to break. The tertiary structure of the enzyme molecule changes, as does the active site. The substrate no longer fits the active site
7 of 8
Distinguish the difference between a competitive and non competitive inhibitor
Competitive inhibitors occupy the active site of an enzyme while non-competitive inhibitors attach to the enzyme at a site other than the active site.
