What we have learnt
- Energy is a fundamental requirement for all life processes, and living organisms transform energy from their environment into usable forms.
- Photosynthesis and cellular respiration are critical processes that demonstrate energy transformation and the interdependence of biological systems.
- Understanding these processes is essential for insights into human health, disease dynamics, and ethical considerations regarding biological manipulation.
Key Concepts
-
Term: Cellular Respiration
Definition: A catabolic process in which organic molecules, primarily glucose, are broken down to release stored chemical energy, converting it into ATP.
-
Term: Photosynthesis
Definition: An anabolic process by which light energy is captured and transformed into chemical energy stored in glucose, with oxygen as a byproduct.
-
Term: Homeostasis
Definition: The state of balance and stability maintained by living organisms, regulated through various physiological mechanisms.
-
Term: Energy Transformation
Definition: The process of converting energy from one form to another, critical in biological systems such as during photosynthesis and respiration.
