What are the four basic macromolecules of life?

Answer 1

1. Carbohydrates: These are sugars and starches that provide energy for your body. They’re the main fuel for your brain and muscles.
2. Proteins: Made of building blocks called amino acids, proteins help build and repair tissues, like muscles and skin. They also do a lot of the work inside cells, like carrying oxygen in your blood.
3. Lipids: These are fats and oils. They store energy for later use, help keep your body warm, and make up the membranes that surround your cells, keeping everything inside.
4. Nucleic Acids: DNA and RNA are types of nucleic acids. They carry your genetic information, which determines your traits and helps guide the creation of proteins that your body needs.

Answer 2

The four basic macromolecules of life are:

1. Carbohydrates – Provide energy and structure; examples include sugars and starches.

2. Lipids – Include fats, oils, and phospholipids; they store energy and form cell membranes.

3. Proteins – Composed of amino acids; they perform a variety of functions, including enzymes, structural components, and signaling.

4. Nucleic Acids – DNA and RNA; they store and transmit genetic information.
