Enzymes

Question 1

Effects of temperature

Answer 1

As the temperature increases, the rate of reaction increases up to a certain point called the optimum temperature, the temperature enzymes work best at, and when this is exceeded enzymes change shape and there is not the correct active site to create enzyme - substrate complexes.

Question 2

Effects of pH

Answer 2

The pH affects the bonds which holds the enzymes shape. If the enzyme is in a lower or higher pH than it should be, the active site could change meaning enzyme-substrate complex molecules cant form as the substrate wont be able to fit in the active sight anymore.

Question 3

Carbohydrate Digestion

Answer 3

Carbohydrases such as amylase catalyse the breakdown of carbohydrates to simple sugars.

Question 4

Protien Digestion

Answer 4

Proteases catalyse the breakdown of proteins to amino acids. Eg. Pepsin

Question 5

Fat Digestion

Answer 5

Lipases catalyse the breakdown of lipids to fatty acids and glycerol.

Question 6

What is the area that is affected by temperature and pH?

Answer 6

The active site of the enzyme

Question 7

What is meant by the term optimum?

Answer 7

It is the best condition, state, temp, pH by where something works best.
