--- **Title: Understanding ATP Hydrolysis Pathways** **The Hydrolysis of ATP** ATP, or Adenosine Triphosphate, is a crucial molecule used for energy transfer within cells. The hydrolysis of ATP can occur via more than one pathway, each yielding different amounts of energy. Below are the options one might encounter: 1. **ATP to ADP, 2 water molecules** 2. **ATP to AMP, 1 water molecule** 3. **ATP to AMP, 2 water molecules** 4. **ATP to ADP, hydride ion** 5. **ATP to AMP, hydride ion** **Question: Which pathway yields the most energy, and what is involved?** This query invites reflection on the processes and energy yields of ATP hydrolysis. When answering, consider the reaction pathways and the transformation of ATP into other molecules such as ADP (Adenosine Diphosphate) or AMP (Adenosine Monophosphate), as well as the specific reactants involved, such as water molecules or hydride ions. The breakdown of ATP into AMP is typically associated with a higher energy release compared to the conversion of ATP into ADP, largely due to the nature of the bonds being broken and formed in the process. **Educational Note:** Understanding these pathways is essential for comprehending cellular energy dynamics and bioenergetics. This knowledge is fundamental in fields such as biochemistry, molecular biology, and physiology. ---

Expert Solution
Step 1
- ATP - stands for adenosine tri-phosphate
- ADP - stands for adenosine di-phosphate
- AMP - stands for adenosine mono-phosphate
- ATP is the source of energy. So breaking of the bonds in presence of water molecules to release energy is called Hydrolysis of ATP. Here the energy is released, therefore it is an exothermic process.
- When one phosphate is released ATP changes to ADP whereas releasing two phosphates it changes to AMP.
