Back to paper

Read the given passage and answer the questions that follow.

From language to cultures - there are annals about India’s diversity writ in bold. At the heart of everything we hold close is our love for food; the aroma from warm hearths wafts in the air, a heady mix of history and meals. So heady, that we often forget that food has a large carbon footprint, and the menace of ever-growing fast-food businesses that contribute the lion’s share to this problem. However, India’s rich traditional and local edible biodiversity, with its focus on home cooked food, presents a ray of hope. Indian members of Relais & Châteaux, in partnership with Slow Food International, hope to bring back our forefathers’ wisdom when it comes to eating, through the Slow Food movement, which started in the 1980s and aims to bring to the fore the connection of plate with people and the planet. Calling for the protection and promotion of traditional techniques associated with regional food cultures is Jaisal Singh, owner of SUJAN group of hotels.

What is the name of a protein that polymerizes into long chains or filaments that form microtubules, hollow fibres that act as the skeletal system for living cells?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Tubulin.

 

  1. Tubulin is a globular protein that polymerizes to form microtubules, which are hollow, tube-like structures inside cells.

  2. Microtubules form part of the cytoskeleton, providing structure, shape, and support to living cells.

  3. They are essential for cell division, intracellular transport, and maintaining cell shape.

  4. Other options:

    • Ferritin stores iron in cells.

    • Fibrinogen is involved in blood clotting.

    • Elastin provides elasticity to tissues but does not form microtubules.
