The electron movement within the ETC generates an electrochemical gradient (proton motive force) whose potential energy drives the flow of protons across the membrane through ATP synthase, making ATP. This diffusion of protons across the membrane (into the cytoplasm for prokaryotes and out of the intermembrane space for eukaryotes) also known as chemiosmosis.

Chemiosmosis

A series of chemical reactions in which electrons are transferred from NADH and FADH2 and passed from one electron carrier to the next until it reaches the final acceptor - the type depending on the type of respiration being performed.

Electron Transport Chain (ETC)

Oxidative Phosphorylation consists of two main parts:

- Electron Transport Chain
- Chemiosmosis

University of Notre Dame

A method for producing ATP in which an inorganic phosphate group is added to ADP using the energy from an electrochemical gradient. The process in cellular respiration in which most ATP are generated

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
