Question

•For each of the following redox reactions (not balanced), define which component is being reduced and which is being oxidized over the course of the reaction. *It may be quite beneficial to draw the element in question and its electrons in its reactant and product state.

1)CO2+ H2O ------> C6H12O6 + O2

Carbon is _________________________   Oxygen is __________________________

2)CH4 + O2 ------>CO2 + H2O

Carbon is _________________________ Oxygen is __________________________

3). (NAD+) + (H+) + (2e-) + (Malate) ------> NADH + Oxaloacetate

NAD+is ___________________ Malate is __________________ into Oxaloacetate

Explanation / Answer

Answer:

1). 6CO2+ 6H2O ------> C6H12O6 + 6O2

Carbon is ______reduced__________________   Oxygen is _______oxidized___________________

2)CH4 + 2O2 ------>CO2 + 2H2O

Carbon is ______oxidized___________________ Oxygen is ________reduced__________________

3). (NAD+) + (H+) + (2e-) + (Malate) ------> NADH + Oxaloacetate

NAD+is ___reduced________________ Malate is ______oxidized____________ into Oxaloacetate

Explanation:

Additionof hydrogen is called reduction and removal of hydrogen is called oxidation.
