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.
