Question:what are he equations???

Answers:Alcohol (Ethanol Fermentation) in yeast C6H12O6 + 2 ADP + 2 Pi + 2 NADH ---> 2 C2H5OH + 2 CO2 + 2 ATP + 2 H20 + 2 NAD+ + 2H+ Lactic acid fermentation C6H12O6 + 2 ADP + 2 Pi + 2 NADH ---> 2 Lactate + 2 ATP + 2 H20 + 2 NAD+ + 2H+

Question:

Answers:Lactic acid fermentation In homolactic fermentation, one molecule of glucose is converted to two molecules of lactic acid: C6H12O6 2 CH3CHOHCOOH In heterolactic fermentation, with one molecule of glucose being converted to one molecule of lactic acid, one molecule of ethanol, and one molecule of carbon dioxide: C6H12O6 CH3CHOHCOOH + C2H5OH + CO2 Alcohol fermentation The chemical equation below summarizes the fermentation of glucose, whose chemical formula is C6H12O6. One glucose molecule is converted into two ethanol molecules and two carbon dioxide molecules: C6H12O6 2C2H5OH + 2CO2 H.

Question:It doesn't have to be in chemical notations. Just use the common name. For instance, instead of saying C6H12O6, all you need to say is glucose.

Answers:Glucose pyruvic acid lactic acid (reversible); glucose pyruvic acid CO2 + EtOH. These can be googled...

Question:please answer i really need you help! also if you could Write equations to show how lactic acid fermentation and alcoholic fermentation compare. that would be awsome! thanks a bunch Cara

Answers:Both produced from pyruvic acid by (CH3COCOOH) fermentation:- 2 CH3COCOOH + 2 NAHD2 --->2 CH3OHCOOH (lactic acid).+2 NAD 2 CH3COCOOH + 2 NADH2-----> 2 CH3CH2OH + 2 CO2 +2 NAD (ethanol + carbon dioxide).
