Final answer:
The Embden-Meyerhof-Parnas (EMP) pathway is the type of glycolysis found in animals and is most common in microbes. The Entner-Doudoroff (ED) pathway is an alternative glycolytic pathway used by some bacteria. The pentose phosphate pathway (PPP) occurs in all cells and is favored when cells require nucleic acid and/or protein synthesis.
Step-by-step explanation:
The Embden-Meyerhof-Parnas (EMP) pathway is the type of glycolysis found in animals and is most common in microbes. This pathway consists of two phases: the energy investment phase, which uses two ATP molecules to modify glucose into two glyceraldehyde 3-phosphate (G3P) molecules, and the energy payoff phase, which extracts energy by oxidizing G3P to pyruvate, producing ATP and NADH. The Entner-Doudoroff (ED) pathway is an alternative glycolytic pathway used by some bacteria. The pentose phosphate pathway (PPP) is a third type of glycolytic pathway that occurs in all cells and is favored when cells require nucleic acid and/or protein synthesis.
