Study Notes
Energy and Cells
- The ultimate source of all energy on Earth is the sun.
Organisms and Energy
- Autotrophic organisms, such as plants, are capable of making their own food.
Cellular Energy
- The common energy currency of cells is ATP (adenosine triphosphate).
- Energy is released from ATP when it is broken down to ADP (adenosine diphosphate).
- ATP has a high-energy phosphate bond that can be broken down to release energy.
Energetic Reactions
- Exergonic reactions proceed with a net release of free energy.
- Endergonic reactions absorb free energy from their surroundings.
- ATP hydrolysis, the breakdown of ATP to ADP, is an example of an exergonic reaction.
ATP and Energy Transfer
- ATP can be used to power cellular processes or reactions when it is in its high-energy state.
- The transfer of energy from one chemical reaction to another is called energy coupling.
- Energy coupling is often linked with an energetically unfavorable reaction, such as ATP regeneration.
ATP Breakdown
- The reversible breakdown of ATP to ADP is called ATP hydrolysis.
- ATP hydrolysis releases energy that can be used to power cellular processes or reactions.
