Which of the following diagrams correctly shows the reaction pathway of a reaction that absorbs energy?

The right answer is D. start with reactants ...

The term "endothermic" refers to a physical phenomenon or chemical reaction that is accompanied by energy absorption.

An endothermic phenomenon is the opposite of an exothermic phenomenon.

The energy balance of a chemical reaction depends on the connections that have formed, on the one hand, and that have been broken, on the other hand. A chemical reaction that requires the absorption of energy is called endothermic. In this case, the energy required to break the bonds of the reactions is greater than that released by the formation of bonds in the products.

For an endothermic chemical reaction to occur, it must be supplied with energy.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
