2020年7月8日 · Examples of endergonic reactions include photosynthesis, the Na + /K + pump for muscle contraction and nerve conduction, protein synthesis, and dissolving potassium chloride in water. An exergonic reaction is a chemical reaction with a negative standard Gibbs free energy, at constant temperature and pressure: ∆G° < 0.

2021年8月23日 · With an exergonic reaction, the figure on the left shows two key things: (1) the difference between the free energy of the reactants and products is negative and (2) the progress of the reaction requires some input of free energy (shown as an energy "hill" or barrier).

2024年9月19日 · Examples of exergonic reactions include exothermic reactions, such as mixing sodium and chlorine to make table salt, combustion, and chemiluminescence (light is the energy that is released). If the temperature of the surroundings increases, the reaction is exothermic.

2024年5月28日 · The main difference between endergonic and exergonic reactions is that the endergonic reaction is non-spontaneous and unfavorable, whereas exergonic reaction is spontaneous and favorable.

2017年5月2日 · In biology, organisms use endergonic reactions to store energy from outside sources. Photosynthesis, which uses the energy of sunlight to create sugars, is an endergonic reaction. So is fatty acid anabolism, in which the energy from food is stored in fat molecules.

Cellular respiration, the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP, is a classic example of an exergonic reaction. Unlike endergonic reactions, exergonic reactions are spontaneous and occur naturally without the …

2017年9月28日 · The terms endergonic and exergonic are used to explain two types of chemical reactions. An endergonic reaction is a non-spontaneous reaction. It does not occur in normal conditions such as at room temperature and atmospheric pressure. An exergonic reaction is the opposite of endergonic reaction. An exergonic reaction is a spontaneous reaction.

In the case of an exergonic reaction, the figure on the left indicates two key things: (1) the difference between the free energy of the reactants and products is negative and (2) the progress of the reaction requires some input of free energy (shown as an energy "hill" or barrier).

Exergonic reactions favor the products over the reactants; therefore, they are spontaneous, and vice versa for endergonic reactions. For example, the oxidation of iron (formation of rust) is an exergonic reaction even though it is very slow.

Endergonic and Exergonic Reactions. Exergonic reactions can be coupled to endergonic reactions. An example of such coupling is the oxidation-reduction reaction. Both reactions require energy to proceed. They use enzymes to lower the activation energy needed to …
