In the following reactions, which is oxidized, and which is reduced? a. A + Be- Ae- + B b. 1/2 O, + 2 H^- H_2O c. NADH + H NAD + 2e- + 2H Draw all of the steps in the cellular respiration pathway. You don\'t have lo include every step in each part, just the substrates for each of the major pathways and the products. You can use Fig. 9.6 as the starting point, but please add the fate of the Carbon molecules from the glucose, where ATP is used/made, and the electron earners arc generated. Use this to answer Q 3 & 4 below. During cellular respiration, how many NADH and FADH are made in total? In which pan of the pathway arc they made, and how many in each pan of the pathway? During cellular respiration, where arc the ATP made; (in which part of the pathway, and how many? BONUS: Why docs cellular respiration not occur when no oxygen is present?

Solution

Bonus: Oxygen has least reduction potential than all other components present in Respiration and it is the final electron acceptor in Electron Transport Chain. If it is not present no component accept electrons and no passive electron transport occurs and leads to no ATP synthesis. So no oxygen, no cellular respiration

4. In cellular respiration 4 ATPs synthecised in Glycolysis by Substrate level phosphorylation due to high energy bond possessing phosphogens. In krebs cycle also 2 ATP equivalents formed. All other ATPs synthecised in the mitochondria.

3. In glycolysis = 2 NADH, Pyruvate dehydroginase complex = 2 NADH, Krebs cycle = 10 NADH & 2 FADH2

Each NADH gives 2.5 ATP & each FADH2 gives 1.5 ATP. So one glucose molecule upon complete oxidation gives total 38 ATPs

1. Taking or accepting electron or proton or decreased + ve charge is Reduction. Where as  Donating electron or proton or increased + ve charge is Oxidation

a. A reduced and B oxidised; b. O reduced and H oxidized; c. NADH oxidized and H reduced
