Question:
Identify the incorrect sentence(s):
• Cellulose is heteropolymer
• Trypsin is a hormone
• Arthropod exoskeleton contains chitin
• Inulin is a polymer of fructose
Identify the incorrect sentence(s):
• Cellulose is heteropolymer
• Trypsin is a hormone
• Arthropod exoskeleton contains chitin
• Inulin is a polymer of fructose
• Cellulose is heteropolymer
• Trypsin is a hormone
• Arthropod exoskeleton contains chitin
• Inulin is a polymer of fructose
Show Hint
Cellulose = Homopolymer of glucose.
Trypsin = Enzyme.
Inulin = Polymer of fructose.
Trypsin = Enzyme.
Inulin = Polymer of fructose.

- I and II only
- I and III only
- III and IV only
- I and IV only
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Analyze Statement I.
Cellulose consists only of glucose units. Therefore it is a homopolymer, not a heteropolymer. Statement I is incorrect.
Step 2: Analyze Statement II.
Trypsin is a digestive enzyme. It is not a hormone. Statement II is incorrect.
Step 3: Analyze Statements III and IV.
Arthropod exoskeleton contains chitin. \(\checkmark\) Inulin is a fructose polymer. \(\checkmark\) Hence only I and II are incorrect. \[ \boxed{\text{Option (A)}} \]
