Document Summary

In which form are electrons transferred during typical redox reactions such as the oxidation of glucose: ans: as h atoms. Nad+ plays a crucial role in the reactions of glycolysis by: ans: accepting electrons from a modified glucose molecule, with the result that modified glucose is partially oxidized to form pyruvate. Which of the following does not occur during the third phase of glycolysis: ans: oxygen consumption. Imagine that a eukaryotic cell carries a mutation impairing its ability to phosphorylate glucose during glycolysis. What is a likely result of this mutation: ans: glucose could move out of the cell, slowing cellular respiration. Phase i: energy investment phase: 2 atps are used up to phosphorylate glucose on 2 carbons. Phase ii: cleavage phase: the 6 carbon glucose molecule is split into 2 molecules (3 carbons each, with a phosphate) Phase iii: playoff phase: the 2 carbon molecules are partially oxidized to generate atp (2 per molecule = 4 atp)
