Biochemistry

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes increase the rate of chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What are substrates in the context of enzymatic reactions?

Back

Substrates are the specific reactants that an enzyme acts on during a chemical reaction.

Front

How do enzymes affect the energy required to start a reaction?

Back

Enzymes lower the energy required to start a reaction, making it easier for the reaction to occur.

Front

What category of biomolecules do sugars and starches belong to?

Back

Sugars and starches belong to the category of carbohydrates.

Front

Why is carbon considered a unique element in biochemistry?

Back

Carbon is unique due to its bonding properties, allowing it to form stable bonds with many elements, including itself.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

What is the difference between a catalyst and an enzyme?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed, while an enzyme is a biological catalyst that specifically acts on substrates.

Front

What is the significance of the active site of an enzyme?

Back

The active site is the region on the enzyme where substrates bind and undergo a chemical reaction.

Front

What are the four main types of macromolecules in biochemistry?

Back

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

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can lead to decreased activity or denaturation.
