In the following reaction, identify the species that are oxidized, those that are reduced. In addition, complete the half reactions associated with each reaction by indicating the stoichiometry of each species in the reaction. CH3CH2CHO + NADH + H+ → CH3CH2CH2OH + NAD+
1. Which species is oxidized?
A. CH3CH2CH2OH is oxidized.
B. NAD+ is oxidized.
C. NADH is oxidized.
D. CH3CH2CHO is oxidized.
2) Which species is reduced?
A. CH3CH2CH2OH is reduced.
B. NAD+ is reduced.
C. NADH is reduced.
D. CH3CH2CHO is reduced.
3) Choose the correctly balanced half reactions.
A. 2CH3CH2CHO + 2H+ + 2e- → 2CH3CH2CH2OH.
B. 2NADH + H+ + 2e- → 2NAD+.
