Question
Which of the following statements is true? *1 pointThe function of nucleic acids is carrying genetic codes and providing the main source of energy for the body.The function of lipids is the main source of energy and structure and support.The function of carbohydrates is energy storage and making up the cell membrane.The function of proteins is structure or support and enzymes speed up the chemical reactions.
Solution
The statement "The function of proteins is structure or support and enzymes speed up the chemical reactions." is true.
Proteins play a crucial role in the body. They do provide structure and support, for example, collagen is a protein that provides structure to our skin and bones. Additionally, proteins act as enzymes which speed up chemical reactions in the body, helping to break down food, build up new molecules, and destroy harmful ones.
The other statements are partially correct but also contain inaccuracies. Nucleic acids do carry genetic information, but they are not the main source of energy for the body. Lipids do provide a source of energy and are involved in structure (such as in cell membranes), but they do not provide support. Carbohydrates are indeed involved in energy storage, but they do not make up the cell membrane.
