Study Notes
Adenosine Triphosphate (ATP)
- ATP consists of a base, a sugar, and three phosphate groups.
- Energy is released from ATP when the last phosphate bond is broken, facilitating cellular processes.
Cellular Respiration
- The sequence of cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain.
- More ATP is produced from the electron transport chain compared to glycolysis and the Krebs cycle.
Germination and Respiration
- Germinating peas at 20ºC exhibit a higher rate of cellular respiration compared to those at 10ºC, indicating temperature's impact on metabolic activity.
Photosynthesis
- Photosynthetic algae synthesize sugars that are later broken down during glycolysis in respiration.
- Sunlight is essential for photosynthesis, as it is converted into chemical energy for use by the organism.
ATP Production Sites
- ATP production occurs primarily in chloroplasts during photosynthesis and in mitochondria during cellular respiration.
- In non-plant organisms, mitochondria are responsible for the majority of ATP production.
Joint Processes in Plants and Animals
- Both green plants and humans utilize cellular respiration to generate ATP.
- Both groups break phosphate bonds in ATP to release energy for biological functions.
Athletic Performance
- During high-energy activities, such as sprinting, the electron transport chain provides most of the energy needed by muscle cells.
Thylakoid Function
- In thylakoids, ATP is produced during light-dependent reactions of photosynthesis, showcasing the compartmentalization of cellular processes.
