- Reactions that absorb heat are distinct from those that release heat. 4. Defining the Terms: - The term for a reaction that absorbs heat is derived from the Greek word "endo", meaning "within", and "thermic", relating to heat. - Therefore, a reaction that absorbs heat is called an...

Reactions that absorb free energy are called: A. potential B. kinetic C. exergonic D. endergonic Catabolic reactions are tightly coupled to reactions that require energy. Can an enzyme make an endergonic reaction exergonic? Why or why not?
For example, sodium and chlorine react so violently that flames can be seen as the exothermic reaction gives off heat. On the other hand, some reactions need to absorb heat from their surroundings to proceed. These reactions are called endothermic. 所有的化学反应都伴随着一个能量的改变。 一些...
Seeing that the pressing needs of the alternative energy source are going high, it is indispensable to look for substitutes to fulfill the future demands. Metal ion batteries from s-block (groups IA and IIA) and some d-block elements are well-adopted as electrode materials for rechargeable ...
In the early 21st century, the so-called “Ni active site” mechanism was proposed, and then turned out to be that the Fe element was the active site (“Fe active site” mechanism); while some recent findings propose that the synergistic effect of Ni and Fe sites are responsible for the...
Chemicalhappen all around us every day. Whether it is a single replacement reaction in the battery of our flashlight, areaction that occurs when iron rusts in the presence of water and oxygen, or an acid-base reaction that happens when we eat – we experiencein almost everything we do. ...
Spontaneous reactions:- The reaction that favors formation of products at condition under which reaction is occuring is called as spontaneous reaction. The spontaneous reaction results in increase in entropy. Answer and Explanation: Become a member and unlock all Study A...
Metabolic processes are constantly taking place in the body.Metabolismis the sum of all of the chemical reactions that are involved in catabolism and anabolism. The reactions governing the breakdown of food to obtain energy are called catabolic reactions. Conversely, anabolic reactions use the energy...
Chemical reactions that release energyare called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture. ...
