hey guys does anaerobic respiration or aerobic respiration release more CO2 in the same time period? :/ I came across a past paper question that said they release the same vol of CO2 but I don't understand why, as anaerobic respiration doesn't involve the Krebs cycle, so I thought it'll release less CO2.

Only yeast fermentation releases CO2 right, and not lactate production. I do aqa btw if it's relevant

You are correct: aerobic respiration results in the production of more CO2 (aerobic produces NO CO2 in animals)

AEROBIC:
C6H12O6 + 6O2 -----> 6CO2 + 6H20

ANAEROBIC:
a) Yeast:
C6H12O6 -----> 2C2H5OH + 2CO2 (ethanol + carbon dioxide)

b) Humans:
C6H212O6 -----> 2C3H6O3 (+ 0CO2) (lactic acid ONLY)

Hope this helps!
