Answer 1

Answer:

Here is your answer

⇒i)In the  first phase of respiration, glucose is broken down into two molecules of pyruvate .This is common in all kinds of organisms.

⇒ii)The fate of pyruvic acid is different in different organisms

Glucose(6 Carbon Molecule) ⇒Pyruvate + (3 carbon molecule)+Energy

There are three types that are

⇒Absence of oxygen(in yeast)=Ethanol(2 carbon molecule)+CO2+Energy

⇒Lack of oxygen(in our muscle)=Lactic acid(3 carbon molecule)+ Energy

⇒Presence of oxygen(in mitochondria) =CO2+Water+Energy
