a) Pyruvate is a three-carbon molecule, so two molecules can be produced from each molecule of glucose. In total, from 4 molecules of glucose that enter glycolysis, there will be produced eight molecules of pyruvate.
b) PA becomes Lactic Acid instead of Acetyl CoA in anaerobic respiration (that is in auscense of oxygen), particularly when the cell carries out lactic acid fermentation, which is what can happen in the mitochondria of muscle cells when faced with a very demanding stimulus.
A main sequence star becomes a GIANT after it uses up the hydrogen in its core.
A giant star is a star with a large radius and luminosity that is much more greater than that of a main sequence star. A giant star is typically formed when a main sequence star deplete its hydrogen gas content. Giant stars usually correspond to the luminosity class ll and lll.
Answer:
continuous flow of energy and cyclic flow of matter in nature
I believe the appropriate answer is Glutamic acid to valine. Sickle cell disease is a blood condition prevalent in people of African and in the tribal people of India. The sickle cell mutation reflects a single change in the amino acid building blocks of oxygen transport protein (hemoglobin). This protein has two sub units the (alpha and beta sub unit), In people with sickle cell the alpha sub-unit is normal. However the beta sub unit has the amino acid Valine at position six instead of the glutamic acid that is present in normal cases
