Enzymes
JUPEB Biology

Enzymes are best described as

When an enzyme is heated to 70 °C its activity is permanently lost. This is because the enzyme has been

The part of an enzyme molecule to which the substrate binds is called the

Salivary amylase acts on starch to produce

The optimum pH of pepsin, the protease in the stomach, is approximately

A competitive inhibitor reduces enzyme activity because it

At a fixed enzyme concentration, the rate of reaction is measured as substrate concentration is increased. The rate

Non-protein organic molecules such as NAD that are required for the activity of some enzymes are called

Within the range below its optimum, raising the temperature by 10 °C approximately doubles the rate of an enzyme-catalysed reaction. This is because

Enzymes speed up reactions by

Lipase digests fats into
