Unit 1 Topic 6 - Respiration Flashcards
Aerobic respiration requires…
oxygen
Fermentation…
Takes place in the absence of oxygen
In stage 1 of respiration…
Glucose is broken down into pyruvate
In stage 1 of respiration how much ATP is produced?
2
Where does stage 1 take place?
The cytoplasm
Is oxygen needed for stage 1?
No
In stage 2 of aerobic respiration…
Pyruvate is broken down into carbon dioxide and water
How much ATP is produced in stage 2?
A large amount
Where does the 2nd stage of respiration take place?
The mitochondria
Does the 2nd stage require oxygen?
Yes
How does fermentation start?
2 ATP
Glucose=======> pyruvate
Fermentation in animal cells
Pyruvate is converted into lactate, takes place in the cytoplasm and no ATP is produced
Fermentation in plant and yeast cells
Pyruvate is converted into ethanol and carbon dioxide, takes place in the cytoplasm and no ATP is produced
