What gets oxidized during glycolysis?

Answer 1

Glucose gets oxidized during glycolysis.

One glucose molecule is transformed into two pyruvate molecules through the ten-step process of glycolysis.

#underbrace("C"_6"H"_12"O"_6)_color(red)("glucose") + "2NAD"^+ + "2HP"_i + "2ADP" → underbrace("2C"_3"H"_3"O"_3)_color(red)("pyruvate") + "2H"_2"O" + "2NADH" + "2H"^+ + "4ATP" #

The average oxidation number of C in glucose (#"C"_6"H"_12"O"_6#) is 0 and +1 in pyruvate (#"C"_3"H"_3"O"_3#), so glucose is oxidized.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
