Carbon monoxide is a poisonous gas because it competes with the gas that binds to hemoglobin in red blood cells. Which of the following would be most directly affected by carbon monoxide poisoning? A. Fat digestion
B. Cellular respiration
C. Synthesis of proteins
D. Breakdown of wastes

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

a. the production of carbon dioxide through the process of photosynthesis
