actually there are four fates of pyruvate.. usually under aerobic conditions it is converted to acetyl co a. and under anerobic conditions it is converted to lactate. it may also b converted to alanine and oxaloactate by enzymes alt and pyruvate carboxlyse respectively

If yeast breaks down glucose by the anaerobic pathway the pyruvate is changed to what?
energy
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.
Which pathway requires oxygen as the final electron acceptor in aerobic respiration?
the citric acid cycle, glycolysis, and pyruvate oxidation
What does glycolysis breakdown?
Metabolic pathway that converts glucose into pyruvate and a small amount of ATP anaerobicly
What are the two products made after glycolysis?
Glycolysis is a metabolic pathway that is responsible for breaking down glucose into two products: pyruvate and ATP. Pyruvate is an end product of glycolysis and is an important intermediate compound in the metabolic pathway. It can be further metabolized to produce various end products such as acetyl-CoA lactate ethanol and carbon dioxide. ATP on the other hand is the energy currency of the cell and is formed through the process of glycolysis. The two products made after glycolysis are: Pyruvate ATP (Adenosine Triphosphate)Pyruvate is a carbohydrate end product of glycolysis and is an important intermediate compound in the metabolic pathway.

Pathway that begins with glucose and ends with pyruvate?
Glycolysis
What products are made by glycolysis?
In Glycolysis the Glucose under goes several process and finally they obtain pyruvate. We have 4 ATP and 2 NADH in this pathway. The pathway was given below.
If yeast breaks down glucose by the anaerobic pathway the pyruvate is changed to what?
energy
Is Pyruvate is a product of glycolysis?
Yes. Pyruvate is a product of glycolysis. This molecule contains three carbons. For every molecule of glucose that enters the glycolytic pathway, two molecules of pyruvate are formed

What enzymes in the glycolysis pathway in the liver catalyze irreversible reactions?
Glucokinase, phosphofructokinase-1, pyruvate kinase

During glycolysis NAD is converted to what?
This is the Glycolysis pathway Glycolysis (the breakdown of glucose to pyruvate and lactate, occurs in the cell cytoplasm): Glucose + 2 ATP + 4 ADP + 2 NAD -> 2 Pyruvate + 2 ADP + 4 ATP + 2 NADH + energy. Oxidation of glucose is known as glycolysis. Glucose is oxidized to either lactate or pyruvate. Under aerobic conditions, the dominant product in most tissues is pyruvate and the pathway is known as aerobic glycolysis. When oxygen is depleted, as for instance during prolonged vigorous exercise, the dominant glycolytic product in many tissues is lactate and the process is known as anaerobic glycolysis. "These studies demonstrate that orderly glycolysis in the erythrocyte is regulated by the NAD-to-NADH ratio and also provide a method that makes possible the in vitro study of erythrocyte glycolysis." The conversion of pyruvate to lactate, under anaerobic conditions, provides the cell with a mechanism for the oxidation of NADH (produced during the G3PDH reaction) to NAD which occurs during the LDH catalyzed reaction. This reduction is required since NAD is a necessary substrate for G3PDH, without which glycolysis will cease. Normally, during aerobic glycolysis the electrons of cytoplasmic NADH are transferred to mitochondrial carriers of the oxidative phosphorylation pathway generating a continuous pool of cytoplasmic NAD NADH
Who received a nobel prize for figuring out the biochemical pathway that produces glucose?
Glycolysis is the metabolic pathway that turns glucose into pyruvate and can also produce glucose FROM pyruvate when working in reverse. The major details of this pathway were illuminated largely by three men: Jakub Karol Parnas, Gustav Embden, and Otto Meyerhof. Of these men, only Meyerhof would receive a Nobel Prize.
Describe a pathway used for degradation of carbohydrates?
This is called the glycolysis pathway. It begins with glucose and ends with pyruvate before entering the Krebs cycle where ATP (adenosine triphosphate) is generated for energy.
Which pathway requires oxygen as the final electron acceptor in aerobic respiration?
the citric acid cycle, glycolysis, and pyruvate oxidation
What does glycolysis breakdown?
Metabolic pathway that converts glucose into pyruvate and a small amount of ATP anaerobicly
