what are considerations for metabolism? correct answers energy yield
balance of reducing power (requires NAD to provide oxidizing power for the pathway
fate of metabolites (pyruvate)
carbon source
why metabolize? correct answers want more energy to grow faster. carbon source, food
provided, and the environments they grow in affect it
what is fermentation? correct answers metabolic process in which NADH is regenerated by
oxidation reactions in a pathway
what are the metabolic pathways in fermented foods correct answers glycolysis (embden
meyerhod parnas)
-homofermentative lactic acid bacteria
-yeast
phosphoketolase
-heterofermentative lactic acid bacteria
-TCA cycle (aerobic metabolism of yeast)
what is primary metabolic energy? correct answers energy generation by substrate level
phosphorylation (ATP generation)
what is secondary metabolic energy? correct answers energy generation by intracellular
consumption of protons (pmf)
what are metabolic pathways in lactic acid bacteria? correct answers homofermentative LAB:
-hexoses are fermented via glycolysis with lactate as the major end product
-pentoses fermented via pentose phosphate pathway
heterofermentative LAB:
-hexoses and pentoses are fermented via the phosphoketolase pathway
bifidobacteria (not true LAB):
-hexoses are fermented via the bifido pathway
what are the end products of Lactic acid bacteria fermentation in glycolysis 3? correct answers
pyruvate --> lactate, NAD
what are the end products of yeast fermentation in glycolysis 3? correct answers pyruvate -->
acteyl coA
pyruvate --> ethanol
