Study Notes
Photosynthesis
- Carbon dioxide is absorbed from the atmosphere during the process of photosynthesis.
- Reactants for photosynthesis include carbon dioxide and water, leading to glucose production and oxygen release.
Anaerobic Respiration
- Weightlifters may experience muscle fatigue due to insufficient oxygen intake, leading to anaerobic respiration.
- Anaerobic respiration occurs when cells switch to this process, enabling small ATP production without oxygen.
- This process converts sugars into alcohol and carbon dioxide, resulting in significantly less ATP than aerobic respiration.
ATP Functionality
- ATP (adenosine triphosphate) serves as the "energy currency" of living cells, enabling energy capture and transfer.
- Energy is stored within the chemical bonds of ATP molecules and released to perform cellular work when bonds are broken.
- ATP is generated during cellular respiration, providing the energy necessary for various cellular activities.
Relationship Between Photosynthesis and Cellular Respiration
- The energy harnessed through photosynthesis is utilized in cellular respiration.
- Sunlight energy is stored in glucose molecules, which is later converted to ATP during cellular respiration for cellular functioning.
Bacterial Respiration
- In experiments with two bacteria species, species X produces carbon dioxide and water, while species Y produces ethyl alcohol and carbon dioxide.
- This indicates that species Y is anaerobic, as it relies on anaerobic cellular respiration which transforms sugars into ethyl alcohol and carbon dioxide in low-oxygen environments.
Differences Between Photosynthesis and Cellular Respiration
- Photosynthesis consumes carbon dioxide, whereas cellular respiration generates carbon dioxide.
- The reactants of photosynthesis are the end products of cellular respiration, establishing a cyclical relationship between the two processes.
