Question

What are the two steps of anaerobic respiration?

Answer 1

1) In yeast :

Glucose (6 carbon molecule) ------(in cytoplasm)------> Pyruvate (3 carbon molecule) + Energy ---------> Ethanol (2 carbon molecule) + carbon dioxide + energy (2 ATP)

2) In muscle cells :

Glucose (6 carbon molecule) ------(in cytoplasm)------> Pyruvate (3 carbon molecule) + Energy ---------> Lactic acid (3 carbon molecule) + energy

Answer 2

Anaerobic respiration takes place in human being as well as in micro organisms like yeast.

This respiration takes place in yeast
glucose---->pyruvic acid(2 molecules)---->ethanol+2ATP

This respiration takes place in muscle tissue of human beings .
glucose---->pyruvic acid----->lactic acid+2ATP
