Question 7 Match the macromolecule with one of its cellular roles in living organisms Column A 2Carbohydrates Proteins 4 acids Column a High energy value storage material and can be used for insulation and cushioning Primary source of energy for most organisms , and are made of at least one monosaccharide Used primarily for protein synthesis determine what and who you are Some types lower the energy of activation for reactions to occur more quickly are made up of amino acids

Answer 1

Here’s the matching of macromolecules from Column A to their cellular roles in living organisms:

1. Carbohydrates

   • Primary source of energy for most organisms, and are made of at least one monosaccharide.

2. Proteins

   • Some types lower the energy of activation for reactions to occur more quickly.

3. Lipids (fats and oils)

   • High energy value storage material and can be used for insulation and cushioning.

4. Nucleic acids

   • Used primarily for protein synthesis and determine what and who you are.

So, the completed matches are:

• Carbohydrates → Primary source of energy for most organisms, and are made of at least one monosaccharide.
• Proteins → Some types lower the energy of activation for reactions to occur more quickly.
• Lipids → High energy value storage material and can be used for insulation and cushioning.
• Nucleic acids → Used primarily for protein synthesis and determine what and who you are.
