The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesisThe discovery of the reaction, by Robin Hill in 1937, demonstrated that the process by which plants produce oxygen is separate from the process that converts carbon dioxide to sugars

The food you eat provides your body with the nutrients it needs to function properly Most foods contain a mix of those essential nutrients, and your body must break it down through a series of chemical reactions to get what it needs in the form best used by your cells
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation
