Overview
Respiration in Plants is a fundamental biological process where plants break down food molecules to release energy for various life activities. Unlike photosynthesis which produces food, respiration involves the oxidation of organic molecules like glucose to generate ATP (energy currency) and releas
Key Concepts
The breaking of C
The breaking of C-C bonds in complex organic molecules through oxidation within cells, leading to energy release. This energy is trapped as ATP throug
The breakdown of glucose into two
The breakdown of glucose into two molecules of pyruvic acid in the cytoplasm. It involves 10 enzyme-controlled steps, uses 2 ATP molecules, and produc
Anaerobic breakdown of pyruvic acid into
Anaerobic breakdown of pyruvic acid into either ethanol and CO2 (alcoholic fermentation) or lactic acid (lactic acid fermentation). Occurs when oxygen
Cyclic pathway in mitochondrial matrix where
Cyclic pathway in mitochondrial matrix where acetyl CoA (from pyruvate) undergoes complete oxidation. Produces 3 NADH, 1 FADH2, 1 ATP, and 3 CO2 per a
Series of electron carriers (Complex I
Series of electron carriers (Complex I-IV) on inner mitochondrial membrane that transfer electrons from NADH and FADH2 to oxygen. Creates proton gradi
