B3 Enzymes

Question 1

What are enzymes?

Answer 1

Enzymes are biological catalysts, which speed up the reaction without using being used up

Question 2

What are enzymes made of?

Answer 2

Protein

Question 3

What is an active site and its properties?

Answer 3

An active site is the most important part of the enzyme

• Each substrate has an active site that is complementary to its shape
• The reaction will only work if the active site exactly fits in with its substrate.

Question 4

What is the perfect temperature or pH for an enzyme called?

Answer 4

• Optimum temperature or pH

Question 5

Enzyme + substrate

Answer 5

Enzyme-substrate complex

Question 6

What if the enzyme is added with some spice?

Answer 6

• The molecules will have more kinetic energy as they move faster
• The enzymes and substrates are more likely to bump to each other
  =>the chemicals reaction is more likely to happen

Question 7

Does all enzyme have the same optimum pH and temperature

Answer 7

Different enzymes have different optimum temp and pH

Question 8

What if enzymes have too much spice?

Answer 8

• the enzyme starts to lose their shape
  -> the active site is no longer fits perfectly with the substrate
  -> the reaction is no longer happened
  => the enzyme is now denatured

Question 9

What if the enzyme have too much life events going around in their life?

Answer 9

• they will denatured
  -> the active site is no longer fits perfectly with the substrate
  -> the reaction is no longer happened
  => the enzyme is now denatured

Question 10

Factors of enzyme?

Answer 10

• pH
• temperature
• enzyme concentration
• substrate concentration

Question 11

What does denatured mean?

Answer 11

Irreversibly damaged
(Too much pH or temperature will break their bond between atoms -> it will no longer fit with the substrate.)
