Originate from the vitamin B group, derivatives of nucleotides, and can be easily reduced or oxidized

Principle Electron Carrier Characteristics

The most common mobile electron carrier used in catabolism (Oxidized form: NAD+, Reduced form: NADH)

Nicotinamide adenine dinucleotide (NAD+/NADH)

An NAD+ variant with an extra phosphate group that plays an important role in anabolic reactions and photosynthesis (Oxidized form: NADP+, Reduced form: NADPH)

Nicotinamide adenine dinucleotide phosphate (NADP+/NADPH)

Certain principle electron carriers play vital roles in key metabolic pathways. These include:

- Nicotinamide adenine dinucleotide (NAD+)
- Nicotinamide adenine dinucleotide phosphate (NADP+)
- Flavin adenine dinucleotide (FAD)

University of Notre Dame

Molecules that bind and transport high-energy electrons between compounds in different pathways. The reduction of these carriers is one way through which energy can be stored after chemical bonds are broken down within nutrients.

OpenStax Biology 2nd Edition

https://openstax.org/details/books/microbiology/

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.
