Question

1 phosphate group 2 amino group 3 carboxyl group 4 hydroxyl group 5 methyl group match each of the options above to the items below. nucleic acid, atp protein fats, oils, steroids, amino acids amino acids, sugars, proteins sugars and alcohols

Explanation:

Nucleic acids and ATP contain phosphate groups. Proteins are made of amino - acids which have amino groups. Fats, oils, steroids, and amino acids can have carboxyl groups. Amino acids, sugars, and proteins can have hydroxyl groups. Sugars and alcohols have hydroxyl groups. Methyl groups are common in various organic molecules but not as distinctively associated as the others in the given pairings.

Answer:

Nucleic acid, ATP: 1. Phosphate group
Protein: 2. Amino group
Fats, oils, steroids, amino acids: 3. Carboxyl group
Amino acids, sugars, proteins: 4. Hydroxyl group
Sugars and alcohols: 4. Hydroxyl group
