Question

Which of the following statements about glycolysis is NOT true? Some ATP is consumed, but even more is produced. A hexose is broken down into two 3-carbon molecules in one reaction. Oxaloacetate is consumed in the first step. NAD^+ is consumed. The ratio of the basic form to the acidic form (depicted) of a certain lysine residue in a protein is found to be exactly 100 at a certain pH. Its pKa is given. Calculate the pH. (Squiggle indicate that chain continues.) Protein structure can be described as having four levels: primary, secondary, tertiary and quaternary. All proteins have structure. Myoglobin, which is related to hemoglobin but does not form a multi-protein complex like hemoglobin forms, but instead remains alone when in solution, lacks structure. (Choose from the 4 levels of structure and write the names on the answer sheet).

Explanation / Answer

The first step of glycolysis is conversion of glucose into glucose-6-phosphate. In overall reaction of glycolysis, two ADP molecules are consumed and two ATP molecules are produced. NAD+ is also consumed in overall. In 4th step, fructose-1,6-bisphosphate (hexose) is converted into dihydroxyacetone phosphate.

So, the statement that is NOT true is C. Oxaloacetate is consumed in the first step.
