Chemical reactions weaken bonds by absorbing energy to break them, and release energy when forming new bonds. This process involves breaking existing chemical bonds through input of energy, and then forming new bonds that release energy. This cycle of bond breaking and bond formation allows for energy to be absorbed and released in a controlled manner.
High-energy bonds can be weakened by processes that require energy input, such as hydrolysis. In hydrolysis, water is used to break the bond and release energy stored in the bond. Enzymes can also catalyze the breakdown of high-energy bonds by providing an alternative pathway with lower activation energy.
Energy is released during the formation of chemical bonds because when atoms come together to form bonds, they release energy that was stored in their chemical bonds. This release of energy helps to stabilize the newly formed compound and makes the overall system more stable.
To calculate the change in enthalpy using bond energies, you need to subtract the total energy required to break the bonds in the reactants from the total energy released when the bonds are formed in the products. This calculation helps determine the overall energy change in a chemical reaction.
Adenosine triphosphate (ATP) is the compound found in living things that supplies energy in one of its chemical bonds directly to cells. This high-energy molecule is often referred to as the "energy currency" of the cell because it helps in various cellular processes by releasing energy stored in its phosphate bonds.

The bonds an be broken by hydrolysis.
Chemical reactions weaken bonds to release energy, such as breaking bonds in reactant molecules to form products. Later, these bonds can reform through reverse reactions or other processes like condensation. Energy is used and released in these transformations.

The high-energy bonds in ATP, specifically the phosphoanhydride bonds, can be weakened by enzymatic hydrolysis, where water molecules are used to break these bonds, releasing energy for cellular processes. Enzymes like ATPases facilitate this reaction, lowering the activation energy required for the bond cleavage. Later, the energy from metabolic processes can be used to reform ATP from ADP and inorganic phosphate (Pi) through phosphorylation, primarily in the mitochondria during cellular respiration.

It gives them more kinetic energy and makes them vibrate. with enough energy (heat), molecules will decompose as the bonds will be broken and the separate elements will be released in gaseous form Hope that helps lm 92
Activation energy to break chemical bonds is provided by an external energy source, typically in the form of heat or light. This additional energy helps overcome the energy barrier required to break the existing bonds and initiate a chemical reaction.
ATP contains energy in the chemical bonds between its phosphate groups.
