Both anaerobic respiration (fermentation) and aerobic respiration are processes that yeast can do.
yeast:
Much more ATP is produced during aerobic respiration, however there is a chance of becoming oxygen poisonous. Less energy-efficient anaerobic respiration enables life in anoxic environments. Muscle function inside the human body depends on both aerobic and anaerobic respiration.
Yeast can carry out both anaerobic respiration (fermentation) and aerobic respiration. Both produces carbon dioxide , fermentation produces a much lower amount of ATP.
Chemical equation of Anaerobic respiration or fermentation:-
( heat)
Chemical equation of Aerobic respiration :-
ATP
Yeasts are unicellular creatures that descended from multicellular ancestors; yet, certain species have the capacity to acquire multicellular traits by generating pseudo hyphae or fake hyphae, which are networks of connected budding cells.
