Carbohydrate Catabolism Flashcards
1
Q
step 1 exoenzymes. name some examples
A
starch broken down to glucose by amylase
cellulose broken down to glucose by cellulase
2
Q
step 2
A
glucose —>pyruvate. 3 possible central metabolic pathway glycolysis, PPP and ED pathway
3
Q
what does PPP and ED pathway stand for
A
pentose phosphate pathway and Entner-Doudoroff pathway
4
Q
how is pyruvate produced by these pathways
A
each use diff enzymes to convert sugars to G3P, then all pathways convert G3P to pyruvate using same enzyme
