Respuesta :
Answer;
B: are primarily sugars and starches
C: are the most readily available source of energy for organisms
D: are the largest of the four main biological macromolecules
Explanation;
-Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. The body breaks down most carbohydrates into the sugar glucose, which is absorbed into the bloodstream.
-They are a major food source and a key form of energy for most organisms. They consist of carbon, hydrogen, and oxygen atoms.
-The four major classes of biomolecules are carbohydrates, proteins, nucleotides, and lipids. Carbohydrates are the most abundant of the four.Carbohydrate derivatives are involved in reproduction, the immune system, the development of disease, and blood clotting.
Answer: The correct answer for the fill in the blank is B), C), and D)
Carbohydrates are the large group of organic compounds, which are formed by carbon, hydrogen, and oxygen.
Carbohydrates are the most important source of energy in the living organisms. They mainly include sugars ( like glucose, fructose) and starches ( present in food like potato, grains, rice).
There are four macromolecules present in the living organisms. These are nucleic acid, carbohydrates, proteins, and lipids. Carbohydrates are the largest of these four macromolecules.
Thus, option B), C), and D) is correct for the carbohydrates.
