Front

Why do different digestive enzymes have different optimum pHs?

Back

Because different enzymes are active in different parts of the digestive system, which have varying pH levels.

Front

What are two factors that affect the rate of activity of an enzyme?

Back

Temperature and pH

Front

Where are lipases produced?

Back

Pancreas

Front

What is the function of amylase?

Back

Amylase breaks down carbohydrates into sugars.

Front

What is the role of lipase in digestion?

Back

Lipase breaks down fats into fatty acids and glycerol.

Front

Define 'enzyme'.

Back

An enzyme is a biological catalyst that speeds up chemical reactions in the body.

Front

What is the significance of pH in enzyme activity?

Back

pH affects the shape and function of enzymes, influencing their activity.

Front

What is the role of protease?

Back

Protease breaks down proteins into amino acids.
