Explanation / Answer

1 ans-  A-C6H12O6 is oxidized and O2 is reduced

In this reaction C6H12O6 has sufficient amount of electron (H+ ion) and oxidation cause the loss of the electron.

2 ans-C-Reduced

NAD+ has a net charge is +1 after adding the 2electron and 1 proton this charge neutralized and form the NADH+ H+

3 ans-B NAD+ has more chemical energy than NADH

Because NAD+ is electron carrier and this is carring the energy potential in the electron and reduced to  NADH+ H+

4ans-E-Cytosol

Glucolysis occured in the cytosol or cytoplasm,this is the first stage of cellular respirationand generate the enegry in the form of ATP,  NADPH and pyruvate.

5 ans-A-substrate-level phosphorylation
