Energy And Respiration Flashcards
Glycolysis
glucose phosphorylated
triose phosphate
NADH ATP
unstable intermediate 4atp
pyruvate
Linked reaction
Dehydrogenation
Decarboxylation
COA
Krebs cycle
Acetyle combines with oxaloacetate = citrate
6c to 6C (nothing)
6C to 5C (co2 nadh)
5C to 4C (same)
4C to 4C (ATP)
4C to 4C ( fadh)
4C to 4C (nothing)
4C to oxaloacetate
Oxidative phosphorylation
H removed from NADH and FADH
H splits
Electron moves through etc
Pumps hydrogen from matrix to interspace membrane
Proton gradient
Facilitated diffusion
ATP synthase rotates
O2+ 4H + 4e → 2H2O
Matrix
Site of linked reaction and Krebs cycle
Enzymes
70 s ribosomes
Circular DNA
Cristae
Site of oxidative phosphorylation
Folded
ATP synthase
Linear arrangement of etc
Outer membrane
Not folded
Permeable
Transport proteins
Inner membrane space
Space between 2 membranes
H ions accumulations
Respiration (aerobic and anaerobic )
Process a breakdown of organic molecules in A series of stages (no presence of oxygen for anaerobic)
Yeast cells
Ethanol pathway
Glucose to pyruvate
Pyruvate gets decarboxylated
2 molecules of ethanal
H acceptor (alcohol dehydrogenase)
Ethanol
Nad regenerated
Glycolysis continues
Mammal cells
Pyruvate itself acts as H acceptor
Reduced to lactic acid (lactate dehydrogenase)
Nad regenerated
Lactate transported to blood plasma
Gets converted back to pyruvate
Oxygen uptake
Rest
Exercise
Recovery (oxygen debt)
Respiratory quotient
Ratio of volume of co2 produced to volume of o2 used per unit time
When more H
More nad produced
More oxidative phosphorylation
More ATP made
Lipids
Energy value 39.4
Most number of c-h bonds
Respiratory quotient: 0.7
