Question

1. what are the four macromolecules? 23. which 3 elements are found in all four macros? 24. what is the monomer of carbohydrates? 25. what are the main three types of carbohydrates? 26. which polysaccharide is found in cell walls of plants? 27. what is the unifying characteristic of lipids? 28. what are the two main types of lipids? 29. where can you find phospholipids? 30. what is the monomer of a protein called? 31. what is the monomer of a nucleic acid? 32. what are the two types of nucleic acids? 33. label the 3 parts of a nucleotide 34. what is the difference between dna and rna? 35. which macromolecule is pictured below? label each

Explanation:

1. Monosaccharides are the monomers of carbohydrates. They are simple - sugar units.
2. The main three types of carbohydrates are monosaccharides, disaccharides, and polysaccharides. Monosaccharides are single - sugar units, disaccharides are two - sugar units, and polysaccharides are long chains of sugar units.
3. Cellulose is the polysaccharide found in plant cell walls. It provides structural support.
4. Phospholipids are found in cell membranes. They form a bilayer structure.
5. The monomer of a protein is called an amino acid. Proteins are made up of long chains of amino acids.
6. The three parts of a nucleotide are a phosphate group, a five - carbon sugar (ribose or deoxyribose), and a nitrogenous base.
7. DNA contains deoxyribose sugar and thymine as a nitrogenous base, while RNA contains ribose sugar and uracil instead of thymine.

Answer:

1. Monosaccharides
2. Monosaccharides, disaccharides, polysaccharides
3. Cellulose
4. Cell membranes
5. Amino acid
6. Phosphate group, five - carbon sugar, nitrogenous base
7. DNA has deoxyribose and thymine; RNA has ribose and uracil
