Enzymes

Front

In the lock-and-key model of enzyme action, the __________ fits into the __________ of the enzyme.

Back

substrate; active site

Front

What is the term for the region on an enzyme where the substrate binds?

Back

active site

Front

What do enzymes typically end with?

Back

-ase

Front

What happens to enzymes when they are heated to a high temperature?

Back

The shape of the enzyme changes and it denatures.

Front

In an enzymatic reaction, the __________ is on the left of the arrow, while the products are to the right of the arrow.

Back

reactant

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to denaturation.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as heat or pH changes.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to another part of the enzyme.
