Question

many glucose molecules may join together to form a ____, such as
3 points
protein, carbonic anhydrase
carbohydrate, cellulose
lipid, rna

atoms of carbon, oxygen, and hydrogen are found in all biological
3 points
macromolecules. which macromolecules are made only of these three
elements?
carbohydrates, proteins, and nucleic acids
lipids, proteins, and nucleic acids
carbohydrates and lipids
carbohydrates only
carbohydrates, lipids, and nucleic acids

Explanation:

For the first question:

• Glucose is a monosaccharide (simple sugar). Carbohydrates are made of sugar units. Cellulose is a polysaccharide (complex carbohydrate) made of glucose units. Proteins are made of amino acids, and carbonic anhydrase is a protein. Lipids have different structures, and RNA is a nucleic acid.

For the second question:

• Carbohydrates have \(C\), \(H\), \(O\). Lipids mainly have \(C\), \(H\), \(O\) (some like phospholipids have other elements but basic structure has \(C\), \(H\), \(O\)). Proteins have \(C\), \(H\), \(O\), \(N\) (and sometimes \(S\)). Nucleic acids (\(DNA\), \(RNA\)) have \(C\), \(H\), \(O\), \(N\), \(P\).

Answer:

First question: carbohydrate, cellulose
Second question: carbohydrates and lipids
