Enzymes

Front

What is a substance called if it speeds up a chemical reaction?

Back

Front

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

Back

Active site

Front

What is the term for a biological catalyst that speeds up chemical reactions in living organisms?

Back

Enzyme

Front

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

Back

The shapes of the enzyme are altered (denatured).

Front

What do we call the temporary complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex

Front

What is the role of enzymes in biochemical reactions?

Back

To lower the activation energy required for the reaction to occur.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH at which it functions best; extreme pH levels can denature the enzyme.

Front

What is a substrate in the context of enzyme activity?

Back

The substance on which an enzyme acts.

Front

What is meant by enzyme specificity?

Back

Enzymes are specific to particular substrates due to the unique shape of their active sites.

Front

What is denaturation in relation to enzymes?

Back

The process in which an enzyme loses its functional shape due to external stress, such as heat or pH changes.
