Kyun Yaad Rehta Hai
Do mini-sentences — pehla energy investment phase (steps 1-4 ATP consume karte hain), doosra payoff phase (steps 5-10 ATP produce karte hain). Semicolon wahan hai jahan molecule do 3-carbon pieces mein split hota hai.
Aksar Poochhe Jaane Wale Sawaal
Glycolysis mein kitne steps hote hain?
Glycolysis mein 10 steps hote hain. Ek glucose (6C) se do pyruvate (3C) bante hain, net gain 2 ATP aur 2 NADH.
Glycolysis cell mein kahan hoti hai?
Glycolysis cytoplasm (cytosol) mein hoti hai. Ise oxygen ki zaroorat nahi — yeh aerobic aur anaerobic dono ka common pathway hai.
Glycolysis ke irreversible steps kaunse hain?
Teen steps irreversible hain: Step 1 (Hexokinase), Step 3 (PFK-1 — committed step), aur Step 10 (Pyruvate kinase).
Glycolysis se net ATP gain kitna hai?
Net gain = 2 ATP per glucose. Investment: 2 ATP (steps 1 and 3). Production: 4 ATP. Net: 4 - 2 = 2 ATP.
