The Human Respiratory System

III. Aerobic Respiration

• B. Process:
• Glucose + 6 O2 ---> 2 H2O + 6 CO2 + 36 ATP
• 1. The Anaerobic phase is the first step of Aerobic respiration (2 ATP made)
• 2.The second (Aerobic) phase is known as the Krebs Cycle (2 ATP made)
• 3. The third phase, which produces the most energy, is called the electron transport chain. (32 ATP made)

IV. Human Respiratory System

• I. Human Respiratory System
• Purpose
• -Your external body surface is dry and impermeable to gases. Lungs provide a thin, moist internal surface for the exchange of gases.
• -Oxygen is required for cellular respiration and carbon dioxide, a waste gas, needs to be removed from the body.
• -Gases are transported throughout the body by hemoglobin in the red blood cells.
