Study Notes
- Biochemistry is the foundation of metabolism in living things.
- Matter and energy are interconnected in living systems.
- Energy can be stored in the chemical bonds of molecules.
- Matter is recycled within living systems, while energy enters and exits the biosphere.
- Organisms can be classified based on their approach to obtaining energy.
- Autotrophs generate their own bio-available energy through photosynthesis.
- Heterotrophs consume other living organisms for energy.
- Photosynthesis and cellular respiration are opposite reactions that form the basis of energy transfer in living systems.
- Matter is conserved in a closed system, while energy behaves differently in an open system.
- Only about 10% of energy is transferred from one organism to the next.
