Question

They provide much of the energy that the cell requires, they contain C, H, O, with twice as many hydrogen as oxygen atoms, they include sugar and starches. What are these characteristics of?

A) Proteins
B) Nucleic acids
C) Carbohydrates
D) Lipids

Answer 1

The characteristics provided are of carbohydrates, which are organic compounds that include sugars and starches, composed of carbon, hydrogen, and oxygen with a general formula
`(CH_2O)_n`.

Step-by-step explanation:

The characteristics mentioned in the question are indicative of carbohydrates. Carbohydrates provide much of the energy that cells require and include sugars and starches. These organic compounds contain the elements carbon (C), hydrogen (H), and oxygen (O), generally with twice as many hydrogen atoms as oxygen atoms, which fits the chemical formula
`(CH_2O)_n`. Examples of carbohydrates are monosaccharides like glucose and polysaccharides such as starch. Glucose is a simple sugar with six carbon atoms and a balance of hydrogen and oxygen atoms. Starch is a complex carbohydrate formed from the bonding of many glucose molecules.
