A non-protein molecule or ion that is required for the proper functioning of an enzyme.
An energy-requiring chemical reaction, which yields products with more potential energy than the reactants. The amount of energy stored in the products equals the difference between the potential energy in the reactants and that in the products.
The passage of a substance through a specific transport protein across a biological membrane down its concentration gradient.
The production of ATP by chemiosmosis during the light reactions of photosynthesis.
A substance that reduces the activity of an enzyme by binding to the enzyme’s active site in place of the substrate.
The study of energy transformation that occurs in a collection of matter.
A description of membrane structure , depicting a cellular membrane as a mosaic of diverse protein molecules embedded in a fluid bilayer of phospholipid molecules.

The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed.
The principle stating that every energy conversion reduces the order of the universe, increasing its entropy. Ordered forms of energy are at least partly converted to heat.
