Aerobic Respiration: Maximum ATP Yields Table

University of Notre Dame

A catabolic pathway requiring oxygen and involving the catabolism of glucose to ultimately release energy necessary for cellular functions. In the final step of the electron transport chain, the final electron acceptor is an oxygen molecule, which gets reduced into water, by cytochrome oxidase.

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.

Cytochrome Oxidase

- Cell lacking genes encoding cytochrome oxidase
- Cell lacking genes encoding enzymes that protect against harmful oxygen radicals
- Not enough oxygen

Circumstances Where Aerobic Respiration is Not Viable

Aerobic Respiration: Maximum ATP Yields

Cellular respiration is composed of four main steps:

- Glycolysis
- Transition Reaction (Pyruvate Oxidation)
- Krebs/Citric Acid Cycle
- Oxidative Phosphorylation
