What is cell fermentation of plants and animals?

Question

pls.....thanks

Answer 1

to add a bit to Laura's explanation ...glycolysis still occurs in aerobic conditions  but in this case the end product, pyruvate is NOT convereted to lactate but rather transported into the mitochondrion to provide fuel ( via acetyl CoA ) to the Kreb's TCA Cycle . So although cglycolysis is always anaerobic in that ir rwquires no oxygen for it energy production ( it uses substrate level phosphorylation ) it has continues to be of evolutionary imporatnce to animal cells because it supplies the fuel for aerobic carbohydate metabolism is all cells that metabolize glucose , not just the white muscle cell.

Answer 2

whenever you see the word 'cell fermentation' think of Anaerobic respiration.

this is when a plant/animal cell undergoes respiration when there's NO oxygen present.

plants and animals are both able to go through anaerobic respiration, but they each result in different products.

plant cells - ethanol and carbon dioxide

animal cells - lactic acid

an example that can help you know which one is which is... think of when you sprint. your muscles start cramping right? it's because you've suddenly gone into hard physical movement, your muscles need energy quick-quick quick, but there isn't enough oxygen in your cells to help make that energy. there's no oxygen! so what do they do? they're forced to create energy ANAEROBICALLY. your muscles cramp because your cells create LACTIC ACID which causes the cramps.

hope that helps!
