Created by Turbolearn AI Respiratory System and Exercise 🏋️‍♀️ The respiratory system plays a crucial role in exercise. As exercise increases, respiratory rate also increases. This is because the body needs more oxygen to function properly during physical activity. Relationship Between Epinephrine and Ventilation Levels 💨 As epinephrine levels increase, ventilation levels also increase. This is a critical relationship, as epinephrine is a hormone that prepares the body for physical activity. Cellular Respiration 🧬 Aerobic Cellular Respiration Aerobic cellular respiration is the process by which cells break down glucose to release stored energy. This process occurs in the presence of oxygen and takes place in the mitochondria, also known as the powerhouse of the cell. "Aerobic cellular respiration is the process by which cells generate energy from glucose in the presence of oxygen." The formula for aerobic cellular respiration is: C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) → 6CO₂ (carbon dioxide) + 6H₂O (water) + ATP (energy) Molecule Formula Glucose C₆H₁₂O₆ Oxygen O₂ Carbon Dioxide CO₂ Water H₂O ATP Adenosine Triphosphate Aerobic cellular respiration produces a significant amount of ATP, between 32-36 ATP molecules per glucose molecule. Anaerobic Cellular Respiration Anaerobic cellular respiration occurs in the absence of oxygen and produces significantly less ATP than aerobic cellular respiration. This process takes place in the cytoplasm of the cell. "Anaerobic cellular respiration is the process by which cells generate energy from glucose in the absence of oxygen." Types of anaerobic cellular respiration include: Ethanol fermentation Lactic acid fermentation Overview of Cellular Respiration Page 1  Created by Turbolearn AI Cellular respiration is a biochemical process that releases energy from organic molecules such as glucose. This process is essential for life and is controlled by enzymes. "Cellular respiration is the process by which cells release energy from organic molecules." There are two main forms of cellular respiration: aerobic and anaerobic. Both types begin with the same process, glycolysis, which is the breakdown of glucose into pyruvate. Type of Cellular Description Respiration Occurs in the presence of oxygen, produces a significant amount Aerobic of ATP Anaerobic Occurs in the absence of oxygen, produces significantly less ATP Glycolysis is an anaerobic process that occurs in the cytoplasm of both prokaryotes and eukaryotes. ATP ATP, or adenosine triphosphate, is a molecule that stores chemical energy that the cell can use. When ATP is used, it becomes ADP (adenosine diphosphate). Page 2
