A spontaneous reaction is one that favors the creation of products under the reaction's current conditions.
What is spontaneous reaction?
A spontaneous reaction is exergonic and has a negative delta G. The system's enthalpy, or total energy, must decrease and its entropy, or disorder, must rise for a chemical reaction to occur with a net release of free energy (- delta G). The energy needed for cellular function comes from spontaneous reactions.
What is importance of spontaneous reactions in the metabolism of a cell?
- Chemical reactions take place in steps to produce and break down complex molecules as part of cellular activities.
- While some of these chemical processes take energy to complete, others happen spontaneously and release energy.
- Cells must continuously produce additional energy to replace the energy spent by the numerous energy-intensive chemical reactions that take place all the time, just as living beings must continuously consume food to replenish their energy stores.
- The term "cell metabolism" refers to all of the chemical processes that occur within of cells, including those that use or produce energy.
