31. They are both ?-donors and ?-acceptors . 32. The three products are RCHO, ammonia, and a reduced acceptor . 33. It uses these compounds as electron acceptors in dihaloelimination reactions. 34. These acceptors form adducts with many zero-valent metals. 35. This involves a pairing of an electron donor and an electron acceptor . 36. Anaerobic respiration is the process of respiration using an electron acceptor other than. 37. Many bacteria use inorganic compounds as hydrogen acceptors to regenerate the NAD +. 38. Not every donor-acceptor combination is thermodynamically possible. 39. Electrons then move spontaneously from donor to acceptor through an electron transport chain. 40. The coin acceptor must be cleaned on a frequent basis to prevent malfunctioning.
