    Cellular respiration is the process by which ... Glycolysis is a metabolic pathway that takes place in ... This would imply that in human mitochondria the 10 protons ...

  3. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    Summary of aerobic respiration. Glycolysis is the metabolic pathway that converts glucose (C 6 H 12 O 6) into pyruvate and, in most organisms, occurs in the liquid part of cells (the cytosol). The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine ...

    In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, ... human biology 146149; C.Michael Hogan. 2011 ...

  5. Respiratory tract - Wikipedia

    en.wikipedia.org/wiki/Respiratory_tract

    The conducting zone also functions to offer a low resistance pathway for airflow. It provides a major defense role in its filtering abilities. The respiratory zone includes the respiratory bronchioles, alveolar ducts, and alveoli, and is the site of oxygen and carbon dioxide exchange with the blood. The respiratory bronchioles and the alveolar ...

  6. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

  7. Breathing - Wikipedia

    en.wikipedia.org/wiki/Breathing

    Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

  8. Anaerobic respiration - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_respiration

    Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.

  9. Exhalation - Wikipedia

    en.wikipedia.org/wiki/Exhalation

    The neurological pathway for involuntary respiration is called the bulbospinal pathway. It is also referred to as the descending respiratory pathway. [10] "The pathway descends along the spinal ventralateral column. The descending tract for autonomic inspiration is located laterally, and the tract for autonomic expiration is located ventrally."
