1.7 Flashcards
what is atp
the energy carting molecule used in cells because it can release energy quickly
wher does glycolysis occur
the cytoplasm
where does the citric acid cycle occur
the matrix of the mitochondria
wher died the electron transport chain occur
in the inner membrane of the mitochondria
what does phosphorylation mean
the addition of a phosphate group
what does dehydrogenase enzymes do
remove hydrogen ions and electrons from intermediates, then passed to NAD forming NADH
what does pyruvate get converted to for the citric acid cycle
an acetyl group that then combine with co enzyme a forming acetyl co enzyme a
what does co enzyme A combine with to form citrate
oxaloactetate
how does the citric acid cycle generate atp
citrate is gradually converted back to oxaloacetate producing atp and releasing atp
what is produced by the citric acid cycle
Co2 and hydrogen
what is produced by glycolysis
2 pyruvate
2 NADH
2 atp
what is the electron transport chain
a series of carrier proteins attached to the inner mitochondrial membrane
how does the electron transport chain produce atp
hydrogen ions are pumped across the inner membrane. they then come back through atp synthase produces atp . hydrogen ions and electrons combine with oxygen to form water
what happens in the energy investment phase
2 atp is used to phosphorylate glucose
what happens in the energy pay off phase
intermediate is broken down into two pyruvate
