Front

What are macromolecules?

Back

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

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 primary function of lipids?

Back

Lipids serve as a source of long-term energy, provide insulation, and make up cell membranes.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What suffix do enzymes typically have?

Back

Enzymes typically end with the suffix '-ase'.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates provide quick energy and serve as structural components in cells.

Front

What macromolecule is primarily responsible for genetic information?

Back

Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails', forming a bilayer in cell membranes.

Front

What is the function of proteins in biological systems?

Back

Proteins serve various functions including catalyzing metabolic reactions (as enzymes), providing structural support, and facilitating communication within and between cells.

Front

How do lipids differ from carbohydrates?

Back

Lipids are hydrophobic and store long-term energy, while carbohydrates are hydrophilic and provide short-term energy.
