		NADH
		Glucose
		FADH2
		O2

Solutions

Expert Solution

Answer: Standard reduction potential of mentioned compounds are as describe in table.

Compound	Standard reduction potential (E’0 )
NADH	-0.320
Glucose	-0.050
FADH2	-0.22
O2	+0.81

Standard reduction potential defines the fate of redox reaction. Standard reduction potential is calculated with reference to Hydrogen electrode which has zero Standard reduction potential. Negative value indicates reducing environment whereas positive value indicated oxidising environment. NADH and FADH2 are reducing agent as they can donate electron to reduce the reductant. Reducing agent makes reductant to gain electron by donating electron. While oxidising agents are quite opposite. O2 makes H to loss electron to form H2O so it is an oxidizing agent.
