5 Questions
What is the primary purpose of anaerobic respiration in a cell?
To produce a limited amount of ATP energy through the incomplete breakdown of glucose in the absence of oxygen.
What is the energy-rich molecule that stores energy in its phosphate bonds and is a byproduct of cellular respiration?
Adenosine triphosphate (ATP)
What is the difference in ATP production between aerobic and anaerobic respiration?
Aerobic respiration produces more ATP than anaerobic respiration.
What happens to ATP when energy is released from its phosphate bonds?
It breaks down into ADP and P (adenosine diphosphate and phosphate).
Where do aerobic and anaerobic respiration take place in a cell?
Aerobic respiration occurs in the cytosol and mitochondria, while anaerobic respiration occurs only in the cytosol.
Study Notes
Energy Release during Respiration
- Energy is released when glucose is broken down during respiration, converting ADP (low energy molecule) to ATP (high energy molecule)
- ATP stores energy in the bonds between the last two phosphates, making it a high energy molecule
ATP Breakdown
- ATP is broken down to form ADP (adenosine diphosphate) and P (phosphate), a lower energy molecule
- This process releases energy, which is used by the cell
Anaerobic Respiration
- Occurs in the absence of oxygen
- Takes place only in the cytosol/cytoplasm of the cell
- Incomplete breakdown of glucose, resulting in significantly less ATP produced
Aerobic Respiration
- Occurs in the presence of oxygen
- Takes place in both the cytosol and mitochondria
- Complete breakdown of glucose, resulting in more ATP produced
Learn about the process of cellular respiration, the role of ATP, and the conversion between ADP and ATP. Understand how energy is released and stored during respiration.
