Question

Which of the following is FALSE about protein molecules?

A.Their function is a result of their shape and folding.
B.Proteins are made up of strands of glucose and joined together in specific sequences.
C.Protein molecules perform many different functions in the body.
D.The order of the amino acids in the protein is important and helps determine its eventual function.

Answer 1

B. they are made up of amino acids, and not glucose

Answer 2

Answer:

B.Proteins are made up of strands of glucose and joined together in specific sequences.

Explanation:

Proteins are made up of amino acids. An amino acid consists of an alpha carbon connected to an amino group (NH2) and a carboxyl (COOH) group. It also has a side chain 'R' which defines its many properties.

Amino acids link to each other via peptide bonds to form a protein. Two amino acids form peptide bond when amino group from one amino acid forms bond with carboxyl group of another amino acid and a water molecule is released in the process. This reaction is called as condensation or dehydration reaction.

Eventually the function and properties of a protein are determined by the amino acids in it and the way the protein has folded and taken a specific shape. Hence, the statement that proteins are made up of strands of glucose is false.
