Study Notes
ATP and ADP
- ATP (adenosine triphosphate) is the primary molecule used by cells for energy transfer and processes.
- ADP (adenosine diphosphate) is a lower-energy form of ATP, which can be converted back into ATP by adding a phosphate group.
Energy Production
- ATP is generated through the breakdown of carbon-based molecules, which include carbohydrates, lipids, and proteins.
- All living cells utilize ATP as their energy source.
Molecule Breakdown
- Carbohydrates, particularly glucose, serve as the most common energy source for ATP production.
- Lipids can yield a greater number of ATP molecules upon breakdown compared to sugars.
- Proteins are less frequently used for ATP production but contain similar energy quantities as carbohydrates.
Relationship Between ATP and ADP
- ATP releases energy when a phosphate group is removed, converting it into ADP.
- The conversion process involves four key steps: energy release, phosphate group removal, formation of ADP, and the re-conversion of ADP back to ATP with an added phosphate.
Chemosynthesis
- Chemosynthesis is a process by which organisms create their own food using chemical reactions, independent of light.
Prefixes Explained
- The prefix "tri-" in ATP indicates the presence of three phosphate groups, while "di-" in ADP indicates only two phosphate groups.
- The prefix "chemo-" signifies chemical processes, combined with "synthesis," meaning these organisms assemble food using chemical sources.
