A. glucose but not cellulose
B. proteins and fats
C. proteins but not amino acids ​

Answer 1

b. proteins and fats

Step-by-step explanation:

proteins contain carbon hydrogen oxygen like the carbohydrates and lipids

fats are large molecules made up of carbon hydrogen and oxygen

Answer 2

Answer: B I think

Protein molecules are often very large and are made up of hundreds to thousands of amino acid units. Fats are large molecules made up of carbon, hydrogen, and oxygen, as are the carbohydrates, but their hydrogen-to-oxygen ratio is higher than 2;1. For this reason, fats contain more energy-storing carbon-hydrogen bonds than carbohydrates.
