Question

How many electron carriers and how many ATP are generated during glycolysis ? Explain where the electron carriers are generated, how the electron carriers ultimately help generate ATP, and how many ATP are generated per electron carrier ?

Answer 1

Here during cellular respiration process glycolysis occurs in the cytoplasm of cell whether the process under aerobic or anaerobic condition.Glycolysis means splitting of glucose molecule into 2 pyruvate molecules(aerobic) or 2 lactic acid molecules(anaerobic).

-ATP is energy molecule here during this process 4 ATP generated but 2 ATP are utilized for activation steps so net ATP produced are 2 and electron carriers NAD+ are converted into NADH by accepting electrons are generated and their number 2 NADH.Electron carriers are generated during conversion of glyceraldehyde -3-phosphate to 1,3 Bisphospoglycerate in glycolysis.

-Here electron carriers like NADH helps in electron transport systems that occurs in inner membrane of mitochondria and ultimately helps in production of ATP(Electron carriers generated during TCA or krebs cycle in mitochondrial matrix also).

Here 3 ATP are generated generated from one NADH molecule(FADH2 is a electron carrier that is produced during TCA cycle that produces 2 ATP per molecule)
