Section 3 - Macromolecules and Enzymes

Front

What is the primary function of enzymes in chemical reactions?

Back

Enzymes speed up the chemical reactions by lowering the activation energy required.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What are nucleotides?

Back

Nucleotides are the monomers that make up nucleic acids like DNA and RNA.

Front

How do temperature and pH affect enzyme activity?

Back

Both temperature and pH can affect the shape and function of enzymes, impacting their efficiency.

Front

What is the role of lipids in animal cells?

Back

Lipids store energy and provide insulation in animal cells.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

Front

What is the function of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

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

Back

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

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, rendering it inactive.
