Biochemistry Review

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the optimal temperature for enzyme activity?

Back

Enzymes work best at a specific temperature, which varies for each enzyme.

Front

What is a substrate in the context of enzymes?

Back

A substrate is a molecule that binds to the active site of an enzyme and is transformed into a product during a chemical reaction.

Front

What happens to enzymes after a chemical reaction?

Back

Enzymes do not get used up in the reaction; they can be reused multiple times.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of nucleic acids in cells?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

How do temperature changes affect enzyme activity?

Back

Temperature changes can increase or decrease enzyme activity; extreme temperatures can denature enzymes, rendering them inactive.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like temperature or pH changes.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is the difference between a product and a substrate?

Back

A substrate is the starting material that binds to an enzyme, while a product is the result of the reaction catalyzed by the enzyme.
