Endergonic reactions:
Can only occur if there is an input of energy
Endergonic reactions are chemical reactions that require energy input to proceed, meaning the products have a higher energy level than the reactants. The energy needed for these reactions is typically supplied in the form of ATP (adenosine triphosphate) or another high-energy molecule. Endergonic reactions are not spontaneous and require the addition of energy to occur.
An example of an endergonic reaction is the synthesis of glucose during photosynthesis in plants. This process requires energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Another example is the formation of peptide bonds between amino acids during protein synthesis, which also requires energy.
Endergonic reactions are important in many biological processes, including muscular contractions, nerve impulses, and the transport of molecules across cell membranes. They are also used in industrial processes, such as the production of fertilizers and the synthesis of polymers.
