Cellular respiration is the process by which cells extract energy from food molecules to power all life activities. This fundamental process occurs in all living organisms and involves breaking down glucose and other nutrients to produce ATP, the universal energy currency of cells.
đŦ Key Concepts
Cells break down glucose to release energy
Aerobic respiration uses oxygen for maximum efficiency
Anaerobic respiration occurs without oxygen
ATP is the universal energy currency of cells
Energy Fact!
A single glucose molecule can yield up to 38 ATP molecules through aerobic respiration - enough energy to power thousands of cellular reactions!
đ¯ Learning Objectives
Understand how cells extract energy from food, compare aerobic and anaerobic respiration, and explore ATP as the energy currency of life.
