Question

9. Which class of organic compounds is used by the body for cell repair and growth?

(1) carbohydrates
(3) minerals
(2) proteins
(4) lipids

Answer 1

Proteins

Protein is a nutrient used to make and repair our body cells (like blood and muscle cells). About 1/2 of your dry body weight is protein. If you do not eat enough carbohydrates, protein will be changed to carbohydrates so that you can get energy.

Answer 2

Proteins

Step-by-step explanation:

Minerals are not organic compounds, and carbs and lipids do not repair/grow cells (lipids are primarily used to store energy and insulate/protect the body and carbs provide a short boost of energy).
