The two phases of the EMP pathway are:

- Energy Investment Phase
- Energy Payoff Phase

Types of glycolytic pathways include:

- Embden-Meyerhof-Parnas (EMP) pathway
- Entner-Doudoroff (ED) Pathway
- Pentose Phospate Pathway (PPP)

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.

Embden-Meyerhof-Parnas (EMP) pathway

A glycolytic pathway that occurs in all cells whose products are used in the biosynthesis of nucleotides and amino acids; thus, it is an important contributor to nucleic acid and protein synthesis. Also known as the phosphogluconate pathway or hexose monophosphate shunt

Pentose Phospate Pathway (PPP)

An alternative glycolytic pathway used by prokaryotes that, depending on the type of bacteria, can be used on its own or in conjunction with the EMP pathway
