The very first step of glucose breakdown is glycolysis which occurs in cytosol and is a 10 step process. In the process one phosphate group from ATP molecules is transferred to glucose for the phosphorylation. Total two step involves in phosphorylation and uses 2 ATP. The end product of complete process is two, 3 carbon compound known as pyruvate which is oxidized to acetyl CoA which enters into Krebs cycle.
So the right answer would be

Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...
