Question

Organic compounds ALL contain the element carbon. Which organic compound, used for stored chemical energy, contains carbon, hydrogen, oxygen, and often phosphorous? a. Lipid b. Starch c. Carbohydrate d. Protein

Answer 1

Answer:

protein and lipids

Explanation:

Proteins, like carbohydrates and lipids, are compounds of carbon hydrogen and oxygen. However, unlike carbohydrates and lipids, proteins also contain the element nitrogen and are hence referred to as nitrogenous compounds. In addition to nitrogen, proteins may contain phosphorus or sulphur or both. Some proteins such as haemoglobin contain other elements such as iron.
