All organisms require energy to complete tasks; the chemical reactions that utilize and release energy are the cell's metabolism.
Organisms consume glucose in order to produce energy, and photosynthetic plants use energy and carbon dioxide to produce glucose.
An anabolic pathway requires energy and builds molecules while a catabolic pathway produces energy and degrades molecules.
The various types of energy include potential, kinetic, and chemical energy.
Free energy, called Gibbs free energy (G), is usable energy or energy that is available to do work.
Activation energy is the energy required for a reaction to proceed and determines the rate of the reaction.
The first law of thermodynamics states that energy may be transferred or transformed, but cannot be created or destroyed.
The second law of thermodynamics states that every energy transfer increases the entropy of the universe due to the loss of usable energy.
Cells couple the exergonic reaction of ATP hydrolysis with endergonic reactions to harness the energy within the bonds of ATP.
A substrate binds to an enzyme, which ultimately promotes the progression of the reaction.
Cells regulate their biochemical processes by inhibiting or activating enzymes.
