36.1 Respiration Aerobic respiration Metabolic pathway which uses O 2 and yields CO 2 as a product Respiration Physiological process by which O 2 enters the internal environment and CO 2 leaves by diffusing across a respiratory surface

Gas Diffusion Across a Respiratory Surface Each gas follows its own partial pressure gradient between air and metabolically active tissues Shapes of respiratory structures are restricted by surface-to-volume ratio and ventilation mechanisms

Respiratory Proteins Respiratory proteins bind and release oxygen; help maintain gradients favoring gas exchange Hemoglobin in red blood cells Myoglobin in muscles

Key Concepts: PRINCIPLES OF GAS EXCHANGE Aerobic respiration uses free oxygen, and its carbon dioxide wastes are removed before the internal environment’s pH shifts dangerously Respiration is the sum of processes that move oxygen from the outside environment to all metabolically active tissues and move carbon dioxide from those tissues to the outside
