Question

Nonliving pairs of colloid aggregation of lipids are _______ and proteinoids are respectively.

• A. Micelles, Coacervates
• B. Liposomes, Micelles
• C. Coacervates, Micelles
• D. Micelles, Liposomes

Hint:

Micelles are formed by lipids and are involved in processes such as digestion and drug delivery, while coacervates form through the aggregation of proteins and have relevance in prebiotic chemistry.

Answer 1

The Correct Option is A

Step 1: Micelles and coacervates are types of colloidal aggregates. Micelles are formed when amphipathic molecules, such as lipids, aggregate in water, with hydrophobic tails inward and hydrophilic heads outward. Coacervates are phase-separated aggregates of proteins or other macromolecules in aqueous solution.

Step 2: Micelles are formed by lipids, and coacervates are formed by proteins. Both are examples of nonliving colloidal aggregates, with their respective structures contributing to their biological functions.

Conclusion: The correct answer is micelles for lipids and coacervates for proteinoids.
