What is the net gain of ATP in glycolysis if it occurs during anaerobic respiration?
🌟 DETAILED EXPLANATION
🧬 What is Glycolysis?
Glycolysis is the breakdown of glucose into pyruvate, generating energy in the form of ATP. It occurs in the cytoplasm and does not require oxygen.
🏷️ Key Steps in Glycolysis:
Glucose Activation: Glucose is converted into intermediates, consuming 2 ATP.
Energy Harvesting: Produces 4 ATP molecules and 2 NADH molecules.
⚡ Net Gain in Anaerobic Conditions:
Total ATP Produced: 4 ATP
ATP Consumed: 2 ATP
Net Gain: 2 ATP
📝 Note:
Under anaerobic conditions, NADH is used for fermentation, and no additional ATP is gained.
