The Fascinating Process of Cellular Respiration Explained

TLDRCellular respiration is the process of converting glucose molecules into ATP, a usable energy molecule. This process involves phosphorylation and the addition of phosphate molecules to adenosine, making it unstable but highly energetic. ATP is then used to provide activation energy for endergonic reactions. Additionally, oxidation and reduction play a crucial role in cellular respiration, with the transfer of electrons and hydrogen ions. NAD is a hydrogen carrier molecule that shuttles electrons and protons between reactions. Understanding cellular respiration is key to comprehending the energy conversion processes in biology and chemistry.
