About Chapter – Respiration in Plants

Respiration in Plants explains how plants break down food molecules to release energy in the form of ATP.

Important concepts covered:

🔹 Cellular respiration
🔹 Glycolysis
🔹 Fermentation
🔹 Aerobic respiration
🔹 Krebs cycle
🔹 Electron transport system
🔹 Oxidative phosphorylation
🔹 Respiratory quotient

Important scientists:

🌱 Hans Krebs – Discovered Krebs cycle
🌱 Gustav Embden, Otto Meyerhof & Jakub Parnas – Glycolysis pathway
🌱 Peter Mitchell – Chemiosmotic theory

Important examples:

✔ Glucose
✔ ATP
✔ Pyruvic acid
✔ Acetyl CoA
✔ NADH
✔ FADH₂

This chapter is important for NEET because questions are commonly asked from pathways, ATP calculation and NCERT diagrams.
