Cellular Respiration

• Cellular Respiration - The process of releasing energy from glucose in the form of ATP
• ATP (Adenosine Triphosphate) - used as cellular energy currency
• Two types of Cellular Respiration - Aerobic Respiration and Anaerobic Respiration
• Aerobic Respiration - respiration which is carried on in the presence of oxygen by which the oxygen is obtained from air or from water which is dissolved
• Aerobic Respiration made of - Glucose + Oxygen --> Carbon Dioxide + Water
• Cellular respiration steps - glycolysis, krebs cycle, electron transport chai
• Glycolysis (glucose splitting reaction) - glucose is broken down into 2 molecules of pyruvate
• Electron Transport Chai (ETC) - The final stage of aerobic respiration in which electrons are transferred from NADH to oxygen
• Kreb's Cycle (citric acid cycle) - a series of reactions that converts pyruvate into acetyl CoA
• Pyruvate - A three-carbon compound formed during cellular respiration.
• Chemiosmosis - involves the pumping of protons through special channels in the membrane of mitochondria from the inner to the outer compartments
• Anaerobic Respiration - type of respiration in which a number of one-celled organisms can carry on in the absence of oxygen
• Anaerobic Respiration made of - Glucose -> Lactic acid + Energy
• Fermentation - process in which energy can be released from glucose even though oxygen is not available
• Fermentation made of - Glucose + Oxygen -> CO2 + H2O + ATP
