Here is a good link for the oxidation states of carbon in glucose [|oxidation states atoms in glucose] This link could help you in biology. Glucose is C6H12O6. Its structural formula is (HO)H2C-C(OH)H-C(OH)H-C(OH)H-C(OH)H-CHO (Note CHO represents an aldehyde).

The oxidation state of carbon 1 is (-1), the oxidation state of C 2 - 5 are all (0), the oxidation state of the aldehyde carbon is (+1). This is calculated using the oxidation state of hydrogen as +1, the oxidation state of oxygen as -2 and the contribution of a carbon bonded to another carbon is 0.

Good practice is to see if you can calculate the oxidation states of each carbon and see if you come up with the answers that I did. This is the type of problem that has been on the multiple choice section of the AP test almost every single year.
