lecture 14 part 2 Flashcards
xwhat is the first part of aerobic respiration
glycolysis
what type of pathway is glycolysis
sugar splitting pathway
where does glycolysis occur
cytosol
how many biochemical reactions occur in glycolysis
10
does glycolysis require O2
no (aeorbic process)
what does glycolysis require
ATP
what does glycolysis produce
4 ATP and 2 NADH
in the glycolysis energy investment phase _ carbon moleqs go to _ carbon olecules
6 -> 3
how many ATP are hydrolyzed per glucose during energy investment phase
2
-phosphate groups are trasnferred to sugar molecules
phosphate groups inc/dec the free enrgy of the sugar molecule during enegry investment phase
increase
during steps 1 & 3 (key regulatory steps) what do cellular conditions do during energy investment phase
speed up or slow down enzymatic rates at these steps (save glucose rarher than use it when the cell has plenty of ATP)
what happens during the energy payoff phase of glycolysis
each 3 carbon sugars generate 1 NADH and 2 ATP
and get two 3 carbon pyruvate moleq per glucose moleq
what is recovered during energy payoff phase
2 ATP from earlier energy investment phase
what does NADH carry
high energy electron, the electron will be donated to the ETC
substrate level phosphorylation
transfer of a phosphate group from an organic moleq (substrate to ADP to make ATP)
