Study Notes
ATP and Energy Metabolism
- ATP (Adenosine Triphosphate) is the primary energy currency of the cell, providing energy for various cellular processes.
- ATP is composed of adenine, a five-carbon sugar (ribose), and three phosphate groups.
ATP-ADP Cycle and Energy Transfer
- ATP plays a crucial role in linking exergonic (energy-releasing) and endergonic (energy-requiring) reactions, allowing energy to be transferred between them.
- During exergonic reactions, ATP is generated, and during endergonic reactions, ATP is broken down to ADP (Adenosine Diphosphate).
ADP and Energy Metabolism
- ADP is the primary recipient of energy from the breakdown of ATP, allowing it to be recycled back into ATP.
- The primary role of ADP is to accept energy from the breakdown of ATP, which can then be used to drive endergonic reactions.
Cellular Respiration and Energy Production
- The primary source of energy used by living organisms is the breakdown of glucose and other nutrients through cellular respiration.
- Cellular respiration is the process by which organisms use oxygen to turn fuel into chemical energy, producing ATP as a byproduct.
Types of Respiration and Energy Production
- Anaerobic respiration is a type of respiration that can break down sugars to generate energy in the absence of oxygen.
- The energy required for endergonic reactions is called activation energy.
ATP Synthesis and Phosphorylation
- The process of combining ADP with a phosphate molecule to make ATP is called phosphorylation.
- The energy released from breaking a molecular bond in ATP comes from the energy stored in the phosphate bonds.
- ATP provides the premier energy molecule in living cells, powering various cellular processes.
