Respiration in Plants

How cells break down food to release energy as ATP - a high-yield, numbers-heavy NEET chapter (2-3 questions/year). It covers gaseous exchange in plants; glycolysis (the EMP pathway) in the cytoplasm; anaerobic fermentation (lactic-acid and alcoholic); aerobic respiration in the mitochondrion - the link reaction, the Krebs (TCA/citric-acid) cycle, and the electron transport system with oxidative phosphorylation and the chemiosmotic hypothesis; the respiratory balance sheet (the 38-ATP account and its assumptions); the amphibolic nature of the pathway; and the respiratory quotient (RQ). Six graded practice sets - two Easy, two Medium, one Hard and one NEET previous-year set - each opening with comprehensive NCERT-anchored notes covering 100% of the current syllabus, followed by single-correct MCQs with full explanations.
