Proteins—have three forms: monosaccharides, disaccharides, and polysaccharides

Select the incorrect association. Carbohydrates—provide the body with energy Proteins—have three forms: monosaccharides, disaccharides, and polysaccharides Carbohydrates—include glucose, sucrose, and starch Lipids—serve to insulate, protect, and store energy Nucleic acids—include DNA and RNA, which control our genetic inheritance

Enzymatic activity

Which one of the following is a function of proteins? Energy storage Energy source Genetic coding Enzymatic activity Insulation

DNA is double-stranded and contains the sugar deoxyribose and the nitrogen-containing base thymine; RNA is single-stranded and contains sugar ribose and the nitrogen-containing base uracil.

DNA and RNA differ in that DNA is single-stranded and contains the sugar ribose and the nitrogen-containing base thymine; RNA is single-stranded and contains sugar deoxyribose and the nitrogen-containing base uracil. DNA is double-stranded and contains the sugar deoxyribose and the nitrogen-containing base thymine; RNA is single-stranded and contains sugar ribose and the nitrogen-containing base uracil.

They are not seen in all living things

How are lipids different from other categories of biological molecules? They do not have carbon. They are not seen in all living things. They are not organic. They will not combine with water. They are much more complex.

Nucleotide

In the diagram below, the monomer that serves as the subunit to creating this organic molecule category is called Glucose. Sugar. Phosphate. Base. Nucleotide.

Dehydration synthesis

The following figure represents which process? Dehydration synthesis Hydrolysis Combustion Denaturation Polyunsaturation

Create cellular energy.

The principle role for sugars in living things is to Form cell membranes. Serve as a form of long-term Energy storage. Produce hormones. Create our genetic code. Create cellular energy.

Joins an amino acid to an adjacent amino acid

What is the function of a peptide bond? Joins nucleotide bases to one another Joins an amino acid to an adjacent amino acid Helps hold one water molecule to an adjacent one Joins a sodium atom to a chloride atom Links oxygen to hydrogen atoms
