Concept introduction:
The formation of oxygen in the light dependent step of the photosynthesis was proved by the Hill reaction. Hill reaction is composed of an oxidation and reduction steps.
Oxidation reaction takes place by removing electrons to get a larger oxidation number to an atom. Consider oxygen in H2O and O2. Both are neutral. Therefore, the total charge of water and oxygen is zero.
H+ in water has
Assume oxygen’s oxidation number as
Assume Oxygen’s oxidation number in O2as
Oxidation number of oxygen has increased. Therefore, an oxidation reaction is taking place.
Likewise, reduction is the lowering of oxidation number of a particular atom.
The oxidation number of Fe has been reduced from

- The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation? (Assume that the CF1CF0-ATP synthase yields 3 ATP/14 H+.)arrow_forward. In another key reaction in glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehyde-3-phosphate (GAP) Because ∆G°′ is positive, the equilibrium lies to the left. (a) Calculate the equilibrium constant and the equilibrium fraction of GAP from the above, at 37 °C. (b) In the cell, depletion of GAP makes the reaction proceed. What will ∆G be if the concentration of GAP is always kept at 1/100 of the concentration of DHAP?arrow_forwardPropose structures for intermediates A and B in the scheme below.

An enzyme catalyzes the reaction A --> B. The initial rate of the reaction was measured as a function of the concentration of A. The following data were obtained: See diagram What is the value of V0 when [A] =43? - 37 nmoles/min - 20 nmoles/min - 50 nmoles/min - 40 nmoles/min - 30 nmoles/min 21. An allosteric regulator decreases the rate of an enzyme reaction by changing - the shape of the enzyme's active site. - binding at the active site of the enzyme. - changing the overall free energy of the reaction. - acting as a coenzyme for the reaction. - decreasing the activation energy of the reaction. 36.
