oxidation and reduction occur…
SIMULTANIOUSLY
half reactions include
the change that ONE element undergoes
Oxidation half reaction
the element that is the REDUCING AGENT/oxidized
note: this element LOSES electrons
Reduction half reaction
the element that is the OXIDIZING AGENT/reduced
note: this element GAINS electrons
Most organisms derive their metabolic energy from….
RESPIRATION
what is respiration
a process in which electrons from nominally glucose, fall to lower-free energy acceptors on the right
most efficient type of respiration
aerobic respiration
