CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
A, C, E, B, D

Cellular Component Mass Ranking

This section details the decreasing order of key cellular components based on their typical percentage presence in total cellular mass.

Component Abundance Overview

  • Water (A): The primary component, making up approximately 60-70% of a cell's mass.
  • Protein (C): The second most abundant, generally constituting 15-20%.
  • Nucleic Acids (E): Includes DNA and RNA, typically present at around 1-1.5%.
  • Carbohydrate (B): Found in smaller proportions, usually near 1%.
  • Lipid (D): Amounts can vary, but often found in concentrations comparable to or less than nucleic acids and carbohydrates in terms of total mass percentage.

Decreasing Order Determination

Arranging these components from highest to lowest percentage presence, considering typical biological composition and the provided options, yields the following sequence:

  1. Water (A)
  2. Protein (C)
  3. Nucleic Acids (E)
  4. Carbohydrate (B)
  5. Lipid (D)

This order is represented by the letters A, C, E, B, D.

Therefore, the correct choice is Option 3.
