Question

part ii. odd one out examine each group of terms. cross out the term that does not belong with the others. then determine which group of organic molecules the terms belong to by using the choices below and write it in the space provided. carbohydrates proteins lipids nucleic acids 1. dna genetic code rna energy source nucleotide 2. monosaccharide sucrose glycogen glycerol c₆h₁₂o₆ 3. amino acid nitrogen glucose enzymes polypeptide 4. fatty acid saturated oils energy storage c₁₂h₂₂o₁₁ part iii. name that biomolecule! for each of the statements below, indicate if it applies to carbohydrates (c), lipids (l), proteins (p), nucleic acids (na), or several of these, by placing a check mark in the appropriate column. 1 contains carbon, hydrogen, and oxygen only 2 used for quick energy 3 found in foods like meat and fish 4 contains nitrogen 5 composed of fatty acids and glycerol 6 monomers are assembled by dehydration synthesis 7 includes enzymes, hormones, and antibodies 8 carries genetic information 9 composed of amino acids 10 contains phosphorus 11 polymers are broken down by hydrolysis

Explanation:

Part II - Odd One Out

1.

• DNA, RNA, and Nucleotide are related to nucleic - acids. Genetic Code is a concept related to how nucleic - acids code for proteins, and Energy Source is not related to nucleic - acids. So, the odd one out is Energy Source, and the group is Nucleic Acids.

2.

• Monosaccharide, Sucrose, Glycogen, and $C_{6}H_{12}O_{6}$ (a general formula for monosaccharides like glucose) are carbohydrates. Glycerol is a component of lipids, not a carbohydrate. So, the odd one out is Glycerol, and the group is Carbohydrates.

3.

• Amino Acid, Enzymes (which are proteins), and Polypeptide are related to proteins. Nitrogen is an element, and Glucose is a carbohydrate. So, the odd one out is Glucose, and the group is Proteins.

4.

• Fatty Acid, Saturated (can refer to saturated fatty acids), Oils (which are lipids), and Energy Storage (lipids are used for energy storage) are related to lipids. $C_{12}H_{22}O_{11}$ (sucrose) is a carbohydrate. So, the odd one out is $C_{12}H_{22}O_{11}$, and the group is Lipids.

Part III - Name that Biomolecule

1.

• Carbohydrates contain only carbon, hydrogen, and oxygen. So, mark C.

2.

• Carbohydrates are used for quick energy. So, mark C.

3.

• Proteins are found in foods like meat and fish. So, mark P.

4.

• Proteins and nucleic acids contain nitrogen. So, mark P and NA.

5.

• Lipids are composed of fatty acids and glycerol. So, mark L.

6.

• Carbohydrates, proteins, and nucleic acids have monomers assembled by dehydration synthesis. So, mark C, P, and NA.

7.

• Proteins include enzymes, hormones, and antibodies. So, mark P.

8.

• Nucleic acids carry genetic information. So, mark NA.

9.

• Proteins are composed of amino acids. So, mark P.

10.

• Nucleic acids contain phosphorus. So, mark NA.

11.

• Carbohydrates, proteins, and nucleic acids (polymers) are broken down by hydrolysis. So, mark C, P, and NA.
