Multiple Choice

Refer to the table below. The table summarizes results of experiments using a group of normal cells and three other groups of the same type of cells, each carrying a different mutation in a membrane receptor protein.The receptor is part of a signal transduction pathway that is stimulated by glucose-6-phosphate.Cells were tested for their ability to respond, via the signal transduction pathway, to a variety of ligand molecule, as shown in the table.Based on these data, which statement about these three mutations is plausible?

• A) Mutations 1, 2, and 3 each broaden the specificity of ligand binding in different ways.
• B) Mutations 1 and 3 broaden the specificity of ligand binding, while mutation 2 eliminates ligand binding.
• C) Mutation 1 broadens the specificity of ligand binding, while mutations 2 and 3 eliminate ligand binding.
• D) Mutation 3 has no effect on ligand binding, while mutations 1 and 2 have dramatic effects on ligand binding.
• E) Mutations 1 and 3 have no effect on ligand binding, while mutation 2 has a dramatic effect on ligand binding.
