Answer:
D. The methyl group of acetyl CoA becomes radio-labeled
Explanation:
During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.
Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.
Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.
Pretty sure its a.) the umbilical cord carries the metabolic waste from the fetus to the placenta where it diffuses into the maternal blood.
Bc metabolic waste just goes from the umbilical cord to the mothers blood
The rate of lung cancer among African to American smokers is thirty percent higher than it is among the white smokers. Even though both white and Africa to American men have similar rates of smoking, African to American smoke fewer cigarettes than white smokers. The likelihood of white women have cancer is high compared to African to American women. In addition, African to American are diagnosed with lung cancer at a very young age.
