Enzymes
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.
Yes, exothermic and endothermic reactions are related to the breaking and forming of bonds. In an exothermic reaction, energy is released when new bonds are formed, resulting in a net release of energy, while in an endothermic reaction, energy is absorbed to break bonds, leading to a net intake of energy. The overall energy change in a reaction depends on the balance between the energy required to break bonds and the energy released when new bonds are formed.
Forming bonds always releases energy. Breaking bonds always requires energy.
When bonds form during cell processes, energy is released.

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.
Chemical reactions such as hydrolysis or combustion can weaken high energy bonds by breaking them and releasing energy. Enzymes can also be involved in catalyzing these reactions to lower the activation energy required to break the bonds.
The bonds an be broken by hydrolysis.

It is stored in bonds and released in energy. Energy is needed to break the chemical bonds, and energy is released when bonds are broken.
No. It requires energy to break bonds, but energy is released when bonds are formed.
Yes, when bonds form between atoms, energy is typically released.
Forming bonds always releases energy. Breaking bonds always requires energy.
