Key Idea Biomass accumulation alone does not sustain life; organisms must utilize stored energy. Cellular respiration is the chemical mechanism that breaks down Energy Storage Molecules to release usable energy.
Section 1
Releasing Energy
Biomass accumulation alone does not sustain life; organisms must utilize stored energy. Cellular respiration is the chemical mechanism that breaks down Energy Storage Molecules to release usable energy.
This process occurs at the cellular level. By breaking the chemical bonds within glucose and fats, respiration liberates the energy required for essential functions such as movement, growth, and thermal regulation.
Section 2
Universal Survival
Respiration is a universal biological requirement, performed by all living things. While plants generate their own food, they—like animals—must break that food down to access its energy.
From microscopic bacteria to large mammals, every organism relies on cellular respiration to power its metabolism. It is the fundamental process of staying alive.
