Study Notes
Plant and Animal Requirements
- Plants require sunlight, carbon dioxide (CO²), and water for survival and growth.
- Animals need oxygen, food, and water to survive.
Chemical Formulas
- Oxygen is represented as O².
- Glucose, the primary energy source, has the formula C⁶H¹²O⁶.
- Carbon dioxide is denoted as CO².
- Water's chemical formula is H²O.
Photosynthesis
- The reactants in the photosynthesis process are carbon dioxide (CO²) and water (H₂O).
- The equation for photosynthesis is: 6CO² + 6H²O → 6O² + C⁶H¹²O₆, indicating that six molecules of carbon dioxide and six molecules of water produce six molecules of oxygen and one molecule of glucose.
Cellular Respiration
- Cellular respiration primarily occurs in the mitochondria and cytoplasm of cells.
- In the cytoplasm, pyruvic acid is generated during glycolysis.
Types of Respiration
- Anaerobic respiration, which does not require oxygen, occurs in the cytoplasm.
- Aerobic respiration, requiring oxygen, takes place in the mitochondria.
Cellular Respiration Equation
- The overall chemical reaction for cellular respiration can be summarized as: C⁶H¹²O⁶ → CO² + H²O + ATP, indicating that glucose is broken down into carbon dioxide, water, and energy (ATP).
