It is likely that, in these reactions, NAD+ functions as an electron acceptor (reducing agent) in redox reactions. functions as an electron donor (oxidizing agent) in redox reactions. functions as a base in acid-base catalytic mechanisms. functions as an electron donor (oxidizing agent) in redox reactions. functions as an electron acceptor (oxidizing agent) in redox reactions. +Z-Part II - Diagnosing the Patient You review with the physician your thoughts about the results of the patient's blood work. Elevated WBC count may indicate an infection or inflammation. Elevated levels of AST, ALT, and ammonia indicate excess nitrogen processing by the liver. However, the low BUN level indicates that ammonia is not being released as urea but instead into the blood, causing hyperammonemia. The ER physician nods in approval and tells you that excess ammonia in the brain can cause neurological damage by inducing changes in the transport of the excitatory amino acid neurotransmitter glutamate, altering brain energy metabolism, and changing the neuronal electric activity by inhibiting the generation of synaptic potentials. He orders the nurse to collect more blood and urine samples for additional testing. He also orders hemodialysis for the patient to reduce the amount of ammonia in the blood and prevent further neurological damage. (Hemodialysis is a treatment that removes…
