How do you produce energy without oxygen?

Answer 1

They use anaerobic fermentation to release energy for cell use. Anaerobic fermentation breaks down glucose (sugar) just like aerobic respiration (which requires oxygen) but does not need oxygen. The drawback is that there is a much smaller yield of usable energy than aerobic respiration. You get much less energy per molecule of sugar. Also the molecule of glucose is not completely broken down like it is in aerobic respiration. Fermentation breaks down a six carbon glucose molecule into shorter molecules of alcohols or acids such as ethyl alcohol or lactic acid and carbon dioxide. This is how yeast makes bread dough rise - the yeast use fermentation to break down sugar for energy, the waste product carbon dioxide forms bubbles in the gluten matrix and the bread rises! It also produces alcohol which is why bread smells sort of beery when it starts to bake. Or you can skip the baking add more water and let the yeast make beer!

Answer 2

You can't make energy with or without oxygen, it can only be transformed. I assume you mean can animals or plants convert (transform) foods into energy in respiration without oxygen and yes they can. Yeast does it when making beer.

Answer 3

During photosynthesis plants utilize energy that they get from the sun to form the high-energy bonds in glucose. The carbon and oxygen in glucose is taken from carbon dioxide and the hydrogen is taken from two water molecules that were broken up to form oxygen and hydrogen ions. This process goes one step further than not using oxygen and it actually releases oxygen, which is the oxygen from the two water molecules it broke down.

Answer 4

Food and water. PS, We don't make energy of oxygen, we make energy of whats in oxygen...

Answer 5

Through the Anaerobic processes; lactic acid becomes the e- acceptor.
