Answer to Question #230315 in Cell Biology for chen

Question

As Rubisco is the most abundant enzyme on earth, so just wanted to know that how much amount of Rubisco enzyme is present in one tree...?

Answer 1

RuBisCo full form:

Ribulose 1,5-bisphosphate carboxylase oxygenase enzyme.

Characteristics:

It is the most abundant enzyme protein on earth. It is important because it is responsible for fixing carbon dioxide present in the atmosphere into energy-rich organic molecules like glucose.

Estimation : 

According to the latest research studies the worldwide mass of rubisco is approximately 30 GT ( gigatonnes) of dry weight in 2x10¹⁴ metre squares of leaves of land plants, and there are approximately 3.04 trillion trees in the world.

1 gigatonne = 1,000,000,000 kilograms 

1 trillion = 1,000,000,000,000 

So, the amount of Rubisco enzyme is present in one tree= 30 GT / 3.04 trillion 

• = 30,000,000,000/3040,000,000,000
• =30/3040
• = 0.009868 kilograms
• 9 gram in terms of dry weight

So, the amount of Rubisco enzyme is present in one tree is 9 grams by dry weight.
