dehydrogenation

During cellular respiration, approximately 34 ATP are produced from one molecule of glucose.  a. How Many ATP are made during glycolysis? b. How many ATP/GTP are made during the Citric Acid Cycle?  c. How many are made during oxidative phosphorylation? d. If you recall electrons from FADH2 pump less proton than electrons from NADH, This is because Complex II does not pump electrons. Because of this FADH2 leads to the production of less ATP, 1 FADH2 produces about 1.5 ATPs Given this value how many ATP are NADH electrons worth?  Please answer all parts with good explanation

GAP + Pi + NAD+ ⟹1,3-BPG + NADH (Reaction 1)      1,3-BPG + ADP  ⟹ 3-PG + ATP (Reaction 2) Which of the following statements concerning the information above is true? Select all that apply. A.Reaction 2 is an example of substrate level phosphorylation B.These reactions are written in a direction that would indicate gluconeogenesis is occurring in the liver C.The linking of Reaction 1 and Reaction 2 by the intermediate 1,3-BPG is an example of coupling of reactions D.Reaction 1 shows a redox reaction where the carbon skeleton is oxidized to generate electrons for a soluble electron carrier E.These reactions are irreversible under cellular conditions
