Question

write the equation for the process of breakdown of glucose ina cell number (a)in the presence of oxygen (b) number in the absence of oxygen

Answer 1

Glucose(6 carbon molecule) first converted into pyruvate(3 carbon molecule) then----

in presence of O2-
CO2 and H2O +36 ATP energy is produced

in absence of O2-
ethanol and carbon dioxide + very less energy

Answer 2

glucose is the 6 carbon molecule which is first converted into pyruvate(3 carbon molecule) in cytoplasm then in the
(a) absence of oxygen it breakdown into ethanol and CO2
glucose = pyruvate = Ethanol + CO2

(b) in the presence of oxygen
glucose = pyruvate = water + CO2 + energy
