By the end of the lecture, students are expected to:. Define a metabolic pathway.. Describe the general metabolic pathways for glucose (production and utilization). Glucose in the bloodstream enters our cells, where it undergoes degradation in a pathway called glycolysis. . Glucose obtained from the digestion of polysaccharides is degraded in glycolysis to pyruvate.. Sucrose…. is . a nonreducing disaccharide . .. composed . of . GLUCOSE. and.

In microbiology, the term ‘fermentation’ can be used to describe either microbial processes that produce useful products or a form of anaerobic microbial growth using internally supplied electron acceptors and generating ATP mainly through substrate-level phosphorylation (SLP)..
