            <p>Respiration in plants represents a critical physiological process where the energy trapped in complex organic molecules is systematically released through the oxidation of C-C bonds. For a NEET aspirant, understanding this chapter requires a precise focus on the cellular sites of these reactions and the specific enzymatic machinery involved. Unlike animals, plants lack specialized respiratory organs, necessitating an analytical look at how individual plant parts manage gas exchange and substrate breakdown. This course dissects the NCERT curriculum to clarify the distinction between external gas exchange and cellular respiration, ensuring that the fundamental concepts of energy currency and metabolic pathways are mastered with the rigor required for competitive examinations.</p>

<p>The journey through this metabolic landscape begins with an investigation into the anaerobic phase of glycolysis in the cytosol and transitions into the mitochondrial matrix for the Tricarboxylic Acid (TCA) cycle. A significant portion of the NEET syllabus focuses on the Electron Transport System (ETS) and oxidative phosphorylation, where the majority of ATP is synthesized via the chemiosmotic mechanism. By examining the respiratory balance sheet, students will learn to calculate theoretical net gains of ATP, while the study of the amphibolic pathway reveals the dual role of respiration in both catabolism and anabolism. Finally, the determination of the Respiratory Quotient (RQ) provides a quantitative measure of the substrates being utilized, completing a comprehensive overview designed to align perfectly with the NCERT textbook and the high-yield patterns of the NEET UG exam.</p>
