Chapter 8, Problem 2FTB
Conditions in which oxygen is absent are described as ____. Some microorganisms break down glucose in the absence of oxygen using ___, which generates only ____ molecules of ATP. This process is followed by ____. in which no more ATP is produced, but the electron-carrier molecule ____ is regenerated so it can be used in further glucose breakdown.
