To solve this problem, we need to match the items in List I with the appropriate descriptions in List II. Let's analyze each item:$\newline \bullet$A. GLUT-4:$\newline$ - GLUT-4 is a glucose transporter found in adipose tissues and striated muscle (skeletal and cardiac).$\newline$ - It enables glucose transport into cells.$\newline$ - This matches with IV.$\newline \bullet$B. Insulin:$\newline$ - Insulin is a hormone produced by the pancreas.$\newline$ - It plays a key role in regulating blood glucose levels.$\newline$ - This matches with I.$\newline \bullet$C. Trypsin:$\newline$ - Trypsin is an enzyme that helps in the digestion of proteins in the small intestine.$\newline$ - It is produced in the pancreas in an inactive form (trypsinogen) and activated in the small intestine.$\newline$ - This matches with II.$\newline \bullet$D. Collagen:$\newline$ - Collagen is a structural protein found in the extracellular matrix of various connective tissues.$\newline$ - It acts as an intercellular ground substance providing structural support.$\newline$ - This matches with III.$\newline$Now, let's match the items from List I with List II:$\newline A \rightarrow IV, B \rightarrow I, C \rightarrow II, D \rightarrow III \newline$This corresponds to Option 3.
