Chapter 9 and 10 Flashcards
During cellular respiration
Glucose is oxidized and oxygen is reduced
During an oxidation reduction reaction
Glucose loses a hydrogen atom and the molecule is oxidized
When is NAD+ reduced to NADH
During both glycolisis and the citration cycle
Glycolisis takes place in the
Cytosol
What generates the ATP that is made during glycolysis
Substrate level phosphorylation
When will glycolosis take place in eukaryotic cells
If oxygen is there or not doesnt matter
What happens when an electron shifts to a more electronegative atom
It loses potentional energy
When glucose is catabolized to a pyruvate
The energy is retained by pyruvate
End products of glycolosis
ATP NADH and pyruvate
When a molecuke is phosphorylorated it
has an increased chemical acitivty and is primed to do cellular work
Investment phase
Glycolosis uses the stored ATP
Paypff phase
Forms a net increase in ATP
When a pyruvate is catabolized in the citric cycle it follows 3 steps which result in
the formation of acetyl CoA, NADH,
H+, and CO2
The oxidation of one pyruvate molecule will feed
2 carbon atoms into the citrid acid cycle
b. During cellular respiration
oxidation of pyruvate to acetyl CoA and the citric cycle release CO2
What is produced for each molecule of glucose metabolized by glycolysis and the citric cycle
12 NADH+FADH2 molecules
During aerobic respiration electrons travel down hill following the sequence
food> NADH> electron transport
chain> oxygen
The mitochondrial inner membrane is where
the protons of the electron transport chain are located
Oxidative phosphorylation (chemiosmosis) produces the most ATP when
glucose is completely oxidized to CO2 and H2O
How much ATP can br produced after the oxidation of 2 glucose molecules
72-76
Where is glycolosis found
In cellular respiration and fermentation
The reduction of acetaldehyde to ethanol is result of
NAD+ being regenerated from NADH
Both alcohol fermentation and lactic acid fermentation do what
Oxidize NADH to NAD+
