Take yeast making alcohol for an example. They take sugar (notice the absence of O2) and make alcohol and CO2. This is why beer and wine have bubbles. Yeast CO2 bubbles can also be found in bread!
the mode of respiration in the absence of air ,more precisely oxygen is called anaerobic respiration. eg:-yeasts
Glycolysis
excerzie
aerobic respiration give more energy than anaerobic respiration.
Anaerobic respiration plays a major role in keeping us alive like when your running around and you feel out of breath anaerobic respiration takes over and give your body energy when your lungs cant
The yeast in beer. It lacks oxygen and so reverts to anaerobic respiration, where the byproduct is alcohol.
cellular respiration: anaerobic:: fermentation :anaerobic
anaerobic respiration there is also fermentation, which is like anaerobic respiration but does not have an electron transport chain
anaerobic respiration
Aerobic respiration requires oxygen and Anaerobic respiration does not require oxygen!
Anaerobic means without air, so there is no respiration.
Anaerobic respiration occurs in the absence of oxygen.
