പ്രോകാരിയോട്ടുകളിൽ, ഒരു ഗ്ലൂക്കോസ് തന്മാത്രയുടെ പൂർണ്ണമായ ഓക്സീകരണം _______________ ATP തന്മാത്രകളുടെ മൊത്തം നേട്ടത്തിന് കാരണമാകുന്നു, അതേസമയം _______________ ATP തന്മാത്രകൾ അസറ്റൈൽ Co-A യുടെ പൂർണ്ണമായ ഓക്സീകരണത്തിൽ നിന്നാണ് രൂപപ്പെടുന്നത്.

A2,38

B4,38

C36 ,12

D38 ,12

Answer:

D. 38 ,12

Read Explanation:

In prokaryotes:

1. Complete oxidation of one molecule of glucose (glycolysis + citric acid cycle + oxidative phosphorylation) results in the net gain of 38 molecules of ATP.

2. Complete oxidation of one molecule of acetyl Co-A (citric acid cycle + oxidative phosphorylation) results in the net gain of 12 molecules of ATP

ATP Yield From Glucose Oxidation

  • The process includes glycolysis, Krebs cycle, and the electron transport chain, leading to a total yield of 38 ATP per glucose in prokaryotic cells.

ATP Yield From Acetyl Co-A Oxidation

  • Each acetyl Co-A molecule entering the Krebs cycle produces:

    • 3 NADH (each ~3 ATP) = 9 ATP

    • 1 FADH2 (each ~2 ATP) = 2 ATP

    • 1 GTP (equivalent to 1 ATP)

  • Thus, the total yield is 12 ATP per acetyl Co-A.
