Question

Describe the attributes of glycolysis with respect to:

i) oxygen requirement; and

ii) ATP yield (high/low, fast/slow).

Answer 1

Glycolysis is the process of converting glucose C₆H₁₂O₁₆ into pyruvate CH3COCOO- and H+.

here, Glucose using only atomic oxygen (O) not O₂ for this conversion , that is it an oxygen independent reaction. but the product pyruvate further may use atmospheric oxygen to metabolize(aerobic), otherwise it is called anaerobic metabolization.

Now, for aerobic respiration; the ATP yield will be more or high,not directly but from pyruvate and NADH + H+ .

i hope you got the answer
