Question

What is an advantage of using genetically engineered human insulin over insulin extracted from animal sources?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
 **Primary Concept**: Advantages of genetically engineered human insulin
 **Related Topics**: Biotechnology, pharmaceutical production, diabetes treatment
 **Prerequisites**: Basic understanding of insulin's function and sources.
## SOLUTION PATHWAY
**Given Information**:
The question asks for an advantage of using genetically engineered human insulin compared to insulin from animals.
**Method & Steps**:
1. Consider the potential advantages of using human insulin produced via genetic engineering.
Reasoning: Animal-derived insulin can cause allergic reactions in some patients due to its foreign protein nature. Genetically engineered human insulin minimizes this risk.
Formula/Rule: N/A
2. Evaluate each option against the potential advantages.
Working: Option A (Reduced risk of allergic reactions) directly addresses the major advantage of using human insulin. Options B, C, and D, while potentially true to some degree, are not the primary or most significant advantage compared to animal-derived insulin.
Key Point: The focus is on comparing the safety and efficacy profiles of the two insulin sources.
3. Select the option that presents the most significant advantage.
Result: Option A – Reduced risk of allergic reactions.
Verification: The reduced risk of allergic reactions is a well-established advantage of human insulin produced by genetic engineering.
 ## OPTION ANALYSIS
A ✓: Reduced risk of allergic reactions. This is the primary advantage. Animal insulin is a foreign protein, and human insulin reduces the risk of immune rejection or allergic reactions.
B :x: Lower production cost. While genetically engineered insulin production might be cost-effective in the long run due to scalability, it's not necessarily cheaper than animal-derived insulin initially.
C :x: Higher insulin potency.  Both types of insulin have similar potency if properly purified and formulated.
D :x: Longer shelf life.  Both types have similar shelf lives when properly stored.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Choosing an option based on cost or potency instead of focusing on the primary advantage of reduced allergic reactions: Focus on the safety aspect when comparing human vs. animal-derived insulin.
  2.Overlooking the immunological differences: Remember that animal insulin is a foreign protein, while human insulin is not, leading to differences in immune response.
 **Quick Tips**:
  1.Remember that genetic engineering allows for the production of human insulin, minimizing the chances of an allergic response.
  2.Think about the immune system's response to foreign proteins.
