What two processes in glucose breakdown are anaerobic?
During glucose breakdown, glycolysis and fermentation occur anaerobically. Glycolysis breaks a glucose molecule into energy and pyruvate. Fermentation uses to the pyruvate to form either ethanol or lactate.
Which metabolic pathway is common to both cellular respiration and fermentation?
The glycolytic pathway is common to both fermentation and cellular respiration. During the course of the metabolic pathway, glucose is broken down to pyruvate. In the presence of oxygen, the pyruvate molecule becomes involved in the TCA cycle. In the absence of oxygen however, fermentation occures. The process is brought about by an enzyme called alcohol dehydrogenase.
What does yeast form during fermentation?
Yeast is a fungus. It forms carbon dioxide and alcohol during fermentation.
Does fermentation releases lactic acid?
Your muscle cells do when you preform lactic acid fermentation.
What happens during glucolysis in cellular respiration?
glucose is changed into pyruvate
During lactic acid fermentation, what is the final electron acceptor?
Pyruvate
The main purpose of reduction of pyruvate to lactate during fermentation is to?
Alcoholic fermentation occurs in organisms such as yeast, as produces ethyl alcohol. Lactic acid fermentation occurs in animals such as humans and produces lactic acid instead of alcohol.

What happens during fermentation which gives rise to achocol?
Yeast enzymes convert grape sugar into ethyl alcohol.

During lactic acid fermentation alcohol and carbon dioxide are produced?
The process that produces ethanol is alcoholic fermentation. The process that produces lactic acid is lactic acid fermentation.
What is the main purpose of reduction of pyruvate to lactate during fermentation?
The main purpose of pyruvate reduction to lactate during fermentation is to convert NADH to NAD plus. Early in the glycolysis process, you'll see that there's a step where NAD plus gets reduced to NADH, and then an ATP is produced.
What does yeast form during fermentation?
Yeast is a fungus. It forms carbon dioxide and alcohol during fermentation.
What is produced by yeast during fermentation?
Carbon Dioxide (C2O) and Alcohol are produced by yeast during fermentation.
What happens if oxygen is absent during the second stage the respiration?
If oxygen is not available during the second stage: the glucose (now pyruvate molecule, after glycolysis) the pyruvate can not enter the mitochondrial membrane so it takes an alternative method of producing ATP Other organisms can continue 'cellular respiration' with out the need of O2 (anaerobic method) such as: •Yeast i) Alcohol fermentation •Human Muscle cells i) Produces lactic acid, which makes your muscles sore
Does fermentation releases lactic acid?
Your muscle cells do when you preform lactic acid fermentation.
What type of microorgansism is alcohol?
Alcohol is not a microorganism but it is produced by yeast during the fermentation of sugars.
