Respiration Flashcards
3 steps in respiration
glycolysis
krebs cycle
ETC
redox reaction formula
CH4 + 2 O2 ——-> CO2 + energy + 2 H2O
which part of the redox is oxidized and which is reduced
example of the oxidation of glucose
roasting a marshmallow over fire and when you take it out it continues to burn when on fire
where does glycolysis happen
cytoplasm
how many glycolysis reactions are there
10
how many carbons does glucose have
6
what do the first 5 reactions of glycolysis need
energy to occur
2 key reasons for glycolysis
generate ATP
break down glucose to prepare for oxidation
which steps of glycolysis are under allosteric control and what does it mean
1 and 3
means once it happens you can’t go back
name of molecule in step 5 of glycolysis
dihydroxyacetone phosphate
what does pyruvic acid do (3)
-alcohol fermentation
-makes beer bubbly
-raises bread
Link reaction
-glycolysis –> krebs cycle
- pyruvate goes into mitochondria to take off CO2 and add conenzyme a
Where dies krebs cycle happen
matrix of the mitochondria
How many times does krebs cycle happen and why
twice, once for each molecule of pyruvate
ETC stages
electron transfer
chemiosmosis
WHat is pushed outside the membrane in ETC
H+ (protons)
Where are the proteins for ETC stored
in the mitochondria wall
ATP synthase
makes ATP by having 3 hydrogen brought back through the membrane and then ADP and Pi are put together
How much ATP is generated in respiration and what is the net ATP
40 is made
38 is net
