Each stage contributes to the production of ATP, the energy currency of the cell.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Glycolysis<\/strong> is the first step and occurs in the cytoplasm. During glycolysis, one glucose molecule (a 6-carbon sugar) is broken down into two molecules of pyruvate (each containing 3 carbon atoms). In this process, four ATP molecules are produced, but two ATP molecules are used up in the early steps of glycolysis. This results in a <strong>net gain of 2 ATP<\/strong> molecules. Additionally, glycolysis also produces 2 molecules of NADH, which are used later in the electron transport chain to generate more ATP.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>The Citric Acid Cycle<\/strong> occurs in the mitochondria and processes the products of glycolysis. Each glucose molecule produces two molecules of acetyl-CoA, which enter the cycle one at a time. For each acetyl-CoA, the cycle produces:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 ATP (or GTP, which is equivalent to ATP)<\/li>\n\n\n\n<li>3 NADH<\/li>\n\n\n\n<li>1 FADH\u2082<\/li>\n<\/ul>\n\n\n\n<p>Since there are two acetyl-CoA molecules per glucose, the <strong>total ATP from the Citric Acid Cycle is 2 ATP<\/strong>. Most of the energy from this cycle is stored in the high-energy electrons of NADH and FADH\u2082, which are used in the electron transport chain to produce more ATP.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Summary:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Glycolysis: Net 2 ATP<\/li>\n\n\n\n<li>Citric Acid Cycle: Net 2 ATP<\/li>\n\n\n\n<li>These numbers do not include the ATP generated from NADH and FADH\u2082 in the electron transport chain.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-164.jpeg\" alt=\"\" class=\"wp-image-29538\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-164.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-164-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many net ATP molecules are generated from one glucose molecule during the Citric acid cycle?
