This organelle contains specialized structures that perform different parts of the aerobic respiration process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Glycolysis<\/strong>, the first step of cellular respiration, takes place not inside the mitochondrion but in the <strong>cytoplasm<\/strong> (label E). During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once pyruvate enters the mitochondrion, the <strong>Electron Transport Chain (ETC)<\/strong> takes place in the <strong>inner mitochondrial membrane<\/strong> (label C). This membrane houses the protein complexes that shuttle electrons from NADH and FADH\u2082 to oxygen. As electrons move through the ETC, <strong>H\u207a ions are pumped into the intermembrane space<\/strong> (label B), creating a proton gradient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The high concentration of H\u207a ions in the intermembrane space creates a chemiosmotic gradient. These protons then flow back into the <strong>mitochondrial matrix<\/strong> (label D) through ATP synthase, driving the phosphorylation of ADP to ATP. This process is known as <strong>oxidative phosphorylation<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Meanwhile, at the end of the ETC, <strong>oxygen acts as the final electron acceptor<\/strong> in the <strong>inner mitochondrial membrane<\/strong> (label C). It combines with electrons and protons to form <strong>water<\/strong>, a vital step to prevent electron buildup and allow the ETC to continue functioning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This coordinated process of electron movement, proton pumping, and ATP synthesis ensures that cells efficiently produce the energy they need to survive.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner9-110.jpeg\" alt=\"\" class=\"wp-image-227600\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Place where glycolysis happens.
