Activation energy is the energy required to initiate a chemical reaction and prevent molecules from breaking down spontaneously. This energy barrier must be overcome for the reaction to proceed, providing a way to regulate the rate of reactions in living organisms.
Endothermic reactions cannot occur spontaneously because they require an input of energy to proceed, making them non-favorable under standard conditions without an external energy source. In contrast, exothermic reactions can occur spontaneously as they release energy, often leading to a decrease in free energy. Therefore, the correct answer is that endothermic reactions cannot occur spontaneously.
An absorbing reaction is likely to start spontaneously because it typically involves the release of energy, which drives the process forward. This energy release can lower the system's overall free energy, making the reaction thermodynamically favorable. Additionally, factors such as increased entropy or the stability of the products compared to the reactants can further promote spontaneity. Overall, these thermodynamic principles create a natural inclination for the reaction to occur without external input.
The word equation for releasing energy is "energy + reactants = products + energy." This represents a process where energy is released as a product of a chemical reaction.
The radioactivity of uranium was discovered in 1896 by the French physicist Henri Becquerel.
An energy-releasing reaction is more likely to start spontaneously. You have to have enough energy to overcome the activation energy barrier (that is to start breaking some bonds). - See more at: http://www.chacha.com/question/what-makes-proteins-the-ideal-types-of-compounds-to-act-as-enzymes#sthash.WWgf8a0I.dpuf

Heat energy moves spontaneously from hot objects to cold objects through a process called heat transfer. This transfer occurs until both objects reach thermal equilibrium, where they have the same temperature.
Spontaneous chemical reactions are those that release energy and result in a decrease in free energy. They typically involve exothermic reactions where the products are more stable than the reactants, leading to a natural tendency for the reaction to occur without the input of additional energy. Examples include combustion reactions and some types of oxidation-reduction reactions.

Yes, most catabolic reactions are energy-releasing processes.
