For the equations below, which molecule is oxidized and which is reduced?

 

H2S + NAD+ --> NADH + S + H+

G3P + NAD+ + Pi --> 1,3dPGA + NADH

check_circleAnswer
Step 1

The chemical reaction of losing and accepting electrons is known as a redox reaction. In a redox reaction, one reactant is oxidized and the other one is reduced simultaneously.

Step 2

If in a chemical reaction a compounds loss its electron, then it is described as oxidized. While if a molecule has accepted an additional electron in the chemical reaction, the molecule is described as reduced .

In the given chemical reaction, the H2S loses it...
