022 - Chemiosmosis

Photosynthesis

process of converting light energy into chemical energy

Cellular respiration

metabolic pathway that breaks down glucose and other food molecules to produce ATP

Anabolic

reaction or pathway that requires an input of energy to synthesize complex molecules from simpler molecules

Endergonic

describes chemical reactions that require energy input

Catabolic

reaction or pathway in which complex molecules are broken down into simpler ones, releasing energy

Exergonic

describes chemical reactions that release free energy

Chemiosmosis

movement of ions down their gradient through a membrane protein; usually refers to the process that produces ATP by harnessing the energy of protons flowing down their gradient which powers ATP synthase

Potential energy

energy type that has the potential to do work; stored energy

Oxidation

loss of electrons

Reduction

gain of electrons

Redox reaction

reaction in which an electron is transferred between two substances

Aerobic respiration

process in which organisms convert energy in the presence of oxygen

Electronegativity

ability of an atom to attract electrons
