Lecture Objectives Know what biochemistry is and its principle. Thank You! 7: Redox Reactions and Electrolysis. A redox reaction is feasible only if the species which has higher potential is reduced i.e., accepts the electrons and the species which has lower reduction potential is oxidized i.e., loses electrons. Electrochemical reactions in water are better understood by balancing redox reactions using the ion-electron method where H +, OH − ion, H 2 O and electrons (to compensate the oxidation changes) are added to cell's half-reactions for oxidation and reduction. The redox role of β-carotene in photosystem II is unique among photosynthetic reaction centers and stems from the very strongly oxidizing intermediates that form in the process of water oxidation. This permits better control over the system. See our Privacy Policy and User Agreement for details. Also, do check our other posts for MyFreeSlides. View by Category Toggle navigation.

BIOCHEMISTRY MODULE Biochemistry Notes 9.2 BIOLOGICAL OXIDATION-REDUCTION 9.2.1 Redox potential – free energy changes In reactions involving oxidation and reduction, the free energy change is proportionate to the tendency of reactants to donate or accept electrons. For example, in the explosive thermite reaction, which is sometimes used to weld railways, electrons are passed from metallic aluminium to ferric oxide: Fe2O3(s) + 2Al(s) → Al2O3(s) + 2Fe(l) This change becomes clearer if we remove the oxygen atoms from the equation: 2Fe3+ + 2Al → 2Al3++ 2Fe We can see that the aluminium atoms lose electrons (become oxidised) and that the electrons pass to the iron ions in ferric oxide, redu… Join me in studying about #electrons, #oxidation, and #reduction Need help in microbiology?
