Study Notes
Photosynthesis
- The primary function of photosynthesis is to convert light energy into chemical energy, specifically in the form of glucose.
- This process occurs in plants and algae, and is essential for their survival and growth.
- Photosynthesis is a vital part of the Earth's ecosystem, as it releases oxygen as a byproduct.
Respiration
- The primary function of respiration is to break down glucose to release energy in the form of ATP (adenosine triphosphate).
- This process occurs in all living organisms, including plants, animals, and microorganisms.
- Respiration is the process that provides energy for all cellular activities, including growth, movement, and reproduction.
Relationship between processes
- Photosynthesis and respiration are interconnected processes.
- The products of photosynthesis (glucose and oxygen) are the reactants of respiration.
- Likewise, the products of respiration (carbon dioxide and water) are the reactants of photosynthesis.
- This interconnectedness forms a cyclical relationship that sustains life on Earth.
Organelles and their roles
- Chloroplasts are the primary organelles responsible for photosynthesis.
- They contain chlorophyll, the pigment that absorbs light energy.
- Mitochondria are the primary organelles responsible for cellular respiration.
- These organelles break down glucose to release energy in the form of ATP.
ATP-ADP cycle
- The ATP-ADP cycle is the primary energy currency of cells.
- ATP is a high-energy molecule that releases energy when broken down into ADP (adenosine diphosphate) and inorganic phosphate.
- This energy is then used to power cellular activities.
Summary
- Photosynthesis and respiration are two essential processes for life on Earth.
- They are interconnected and form a cyclical relationship that sustains life.
- Chloroplasts and mitochondria are the organelles responsible for these processes.
- The ATP-ADP cycle is the primary energy currency of cells and is essential for cellular activities.
