CH 7 Cellular Respiration Flashcards
Where do the following stages take place in a eukaryotic cell?GlycolysisAcetyl-coal synthesisCitric acid cycleOxidative phosphorylation
CytoplasmMitochondria MitochondriaMitochondria respectively
Define oxidation and reduction
Loss of electrons therefore reducing agentGain of electrons therefore oxidizing agent
When energy is released in the form of ATP where is it stored during cell respiration?
Electron carriers
What are the two ways the cell can produce ATP?
Substrate level phosphorylation and oxidative phosphorylation
Define substrate level phosphorylation
Transfer of a phosphate group to ADP to create ATP occurs during stages 1 and 3
How many ATP are produced during glycolysis
7 2 from SLP( substrate level phosphorylation )5 from OP ( oxidative phosphorylation)
How many ATP are produce during acetyl coa synthesis?
5 all from OP
How many ATP are produced during the citric acid cycle?
202 from SLP18 from OP
Is phase 1 of glycolysis endergonic?
Yes it consumes 2 ATP to trap glucose into the cell for the next phase
What happens in phase 2 of glycolysis?
Cleavage phase breaking sugar isomers into two
What happens in phase 3 of glycolysis?
Production of 4 ATP and 2 NADH and 2 pyruvate continuing
Define dehydrogenase complex
Group of enzymes that catalyze the reaction of pyruvate to acetyl coa
Describe the citric acid cycle
Oxaloacetate and acetyl coa form citrateResults in: 2 ATP, 6NADH and 2FADH
By which complex do electrons from NADH enter the electron transport chain?
Complex 1
By which complex do electrons from FADH enter the electron transport chain?
Complex 2
