Cellular Respiration Notes

Cellular Respiration

Introduction

• Cellular respiration is often confused with respiration (breathing), but it occurs at the cellular level within mitochondria.
• It involves breaking down food in the presence of oxygen to produce ATP (energy).
• Bacteria can also perform respiration using their outer membranes, even without mitochondria.
• Track athletes like Usain Bolt use cellular respiration to generate ATP for muscle movement.

Pace and Respiration

• A study of world record paces from 100m to 10,000m shows a rapid drop-off in pace that stabilizes over longer distances.
• Sprinting relies on quick energy production, but endurance running can maintain a steadier pace.

Types of Respiration

• Aerobic respiration: Occurs in the presence of oxygen.
• Anaerobic respiration: A
