Exothermic reactions release energy.
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
Endothermic reactions require energy while exothermic reactions release energy.
Yes, catabolic reactions release energy by breaking down molecules into smaller components.
exothermic reactions
Exergonic vs. Endergonic reactions: exergonic release more energy than they absorb. Endergonic reactions absorb more energy than they release.Exergonic reactions release energy while endergonic reactions absorb energy.
energy
Yes, endergonic reactions absorb more energy than they release. These reactions require an input of energy in order to proceed, and the energy absorbed is greater than the energy released during the reaction.
Exothremic Reactions
Yes, the spontaneity of exergonic reactions is determined by their tendency to release energy.
This is chemical energy, since chemical reactions are required to release it
Nuclear reactions release more energy than chemical reactions because they involve changes in the nucleus of an atom, where much larger amounts of energy are stored compared to the energy stored in the electron shells involved in chemical reactions.
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
