What vitamins are required for operation of the pyruvate dehydrogenase enzyme complex?
Thiamin, niacin, and riboflavin
Where does glycol sis take place?
Glycolysis, which converts glucose into pyruvate, occurs in the cytoplasm. The cytoplasm is a thick liquid.
What enzyme converts glucose to ethanol during fermentation?
Zymase, found in yeast
What is lactate dehydrogenase?
It is a glycolytic enzyme responsible for converting pyruvate to lactate. Enzymes are proteins that act as catalysts to speed up reactions.
What are the building blocks in the body's synthesis and elongation of fatty acids?
acetylCoA
What does Decarboxylation of pyruvate produces?
decarboxylation means removal of co2 from the reaction
What is the Calvin cycle responsible for?
It is responsible for the breakdown of pyruvate/acetylCoA into 1ATP, 4NADH, and 1FADH per cycle. It is a part of cellular respiration.
The enzyme pyruvate kinase is responsible for catalyzing the conversion of phosphoenolpyruvate into?
pyruvate
Does thiamine play a role in citric acid cycle?
Thiamine (Vitamin B_1) is an important component of the pyruvate dehydrogenase complex--the enzyme complex which converts pyruvate to acetyl-CoA. This specific reaction is the "Link Reaction" which connects glycolysis and the citric acid cycle.
How does pyruvate kinase deficiency affect the body?
PKD is caused by a deficiency in the enzyme, pyruvate kinase.
Which enzyme(s) bypass the pyruvate kinase reaction of glycolysis in gluconeogenesis?
pyruvate carboxylase and phosphoenolpyruvate carboxykinase (PEPCK)
What enzyme converts the glucose into bigger molecules?
Starch is an enzyme that converts the glucose into bigger molecules. Starch is proteins and fat.
What will happen to the enzyme active site after NADH binds there?
After the NADH binds there the binding of pyruvate happens at the enzyme active site.
What is needed to make pyruvate?
Pyruvate is an organic acid and is a ketone functional group. It is made up of glucose, acetyl co enzyme A, alanine, and ethanol.
What enzyme is used in blood clotting?
Prothrombinase converts prothrombin into enzyme thrombin.
The enzyme that converts angiotensinogen into antiotensin you is?
renin
What enzyme converts tyrosine into melanin?
tyrosinase
