Transport proteins are compared to enzymes. Which of the following is not a reason for this comparison?
Both transporters and enzymes reach a maximum rate when the ligand binding sites are saturated.
Similar to catalysis done by enzymes, transporters “catalyze” the transport of molecules by lowering the activation energy of transport.
Both can form a complex between the protein (enzyme or transporter) and the substrate (reactant or compound being transported).
Both can undergo conformational changes in response to ligand binding.
All of these statements are correct.
Answer
All of these statements are correct.
both change conformation when bound and as enzymes minimize the activation energy,, the same is the case with transporters among the other listed similarities
Explanation
All of the statements are correct and describe why the two are assumed to be the same. For instance, the transmembrane passage of polar compounds and ions is made possible by the transporters or membrane proteins that lower the activation energy for transport by providing an alternative path for specific solutes through the lipid bilayer which has shown to cause conformational changes as it is the case with enzymes
