Read the following statements regarding biomolecules: (A) Inulin is a polymer of fructose. (B) Abrin and ricin are secondary metabolites categorized as lectins. (C) The competitive inhibitor of succinic dehydrogenase is malonate. (D) GLUT-4 is a protein that enables glucose transport into cells. How many of the above statements are correct?

Step-by-step solution

Statement (A) is correct as inulin is a homopolymer of fructose. Statement (B) is incorrect because abrin and ricin are categorized as toxins, whereas Concanavalin A is a lectin. Statement (C) is correct as malonate closely resembles succinate in structure and acts as a competitive inhibitor of succinic dehydrogenase. Statement (D) is correct as GLUT-4 is a protein that enables glucose transport into cells. Therefore, exactly three statements are correct. Answer: Only three
