Enzymes

Question 1

What happens to enzymes when the temperature increases

Answer 1

If you increase the temperature you increase kinetic energy. As a result enzymes and substrates collide more frequently which will cause more reactions to take place. However the enzyme can only work well up to a certain point. (optimum) Once the enzyme passes its optimum it starts to denature which means the shape of the active site changes so the substrate can no longer fit which means no more reactions can take place.

Question 2

What are the effects on an enzyme when the ph changes

Answer 2

All enzymes have an optimum pH at which they work best. In conditions with lower/higher pH, the pH strats to interfere with bonds that hold the enzyme in the correct shape, if the shape of the enzyme changes then the shape of the active site changes which means that no enzyme-substrate complexes can form which then causes the reactions to slow or stop.

Question 3

Carbohydrates in digestion

Answer 3

Carbohydrates such as amylase complete the breakdown of carbohydrates into simple sugars

Question 4

Protein in digestion

Answer 4

Proteins such as proteases complete the breakdown of protein into amino acids

Question 5

Fats in digestion

Answer 5

Fats such as lipase complete the breakdown of lipids into fatty acids and glycerol
