11. The redox state of the cysteines determines the fluorescent properties of roGFP. 12. Anthony and Zatman also found the unknown redox cofactor in alcohol dehydrogenase. 13. They may also initiate specific biological processes by redox signaling. 14. Redox reactions involve a gain or loss of electrons from a molecule.15. First, redox potential is negative enough to reduce ferredoxin. 16. Typical types of change include oxidization including combustion, redox reactions etc. 17. Flavoproteins are mainly located in the mitochondria because of their redox power. 18. The energy comes from redox coupling, what ME is all about. 19. PDE5 activity is modulated by a rapidly reversible redox switch. 20. The reference half cell consists of a redox standard of known potential.
