Catabolic Pathways Flashcards
What initiates polymer breakdown?
hydrolases (abundance of water)
What is the end product of glycolysis?
pyruvate
What is glycolysis?
process that extracts energy from glucose by splitting it into two 3 carbon pyruvate molecules and 2 ATP and NADH
What fermentation pathway is used by heterolactic acid bacteria?
phosphoketolase pathway
What is the key enzyme in the Etner Douderoff pathway?
KDPG aldoase
What does the Krebs (TCA) cycle produce?
reduced coenzymes NADH, FADH2,
What is fermentation?
the use of organic molecules as terminal electron acceptors
What organism produces ethanol?
saccharomyces
What organism produces acetone?
clostridium
What organism produces ethanoic acid?
Escherichia acetobacter
What organism produces lactic acid?
lactobaccillus streptococcus
What organism produces propanoic acid?
propionibacterium
What do feed enzymes do?
increase the digestibility of nutrients
What is the heterolactic pathway?
glycolic pathway, enzyme phosphoketolase cleaves pentose phosphate into acetyl phosphate (ethanol) and glyceraldehyde 3 phosphate (lactic acid) , produces 1 ATP
What is the Etner Douderoff pathway
yields 2 pyruvic acid from glucose, ethanol produced, 1 ATP
