Insulin derived from pigs, which closely resembles human insulin, is known as which type?

• A. Bovine insulin
• B. Human insulin
• C. Recombinant insulin
• D. Porcine insulin

Answer: (D)

The main idea is about where insulin comes from and how similar it is to human insulin. Porcine insulin is insulin sourced from pigs and is known for its close resemblance to human insulin, which is why it was widely used before recombinant human insulin became common. Because the pig’s insulin molecule is very similar to ours, it tends to work well with fewer immune reactions compared to other animal sources. Bovine insulin, from cows, has more differences from human insulin and is less similar. Recombinant insulin is produced by genetic engineering and is designed to be identical or nearly identical to human insulin, not derived from animals. So the pig-derived option is called porcine insulin.
