1.6. Respiration Flashcards
In which cells does respiration take place?
ALL OF THEM
What is the purpose of respiration?
Getting energy from food
What controls respiration?
Enzymes
What is the name of the molecule made from the energy released from the breakdown of glucose?
ATP
State 5 processes that occur within a cell that requires ATP.
- Muscle cell contraction
- Cell division
- Protein synthesis
- Transmission of nerve impulses
- Active transport
During the first stage of respiration, what is glucose broken down into?
2 molecules of pyruvate
How many molecules of ATP are generated during this stage?
2 ATP
Is oxygen required during the first stage of aerobic respiration?
No
If oxygen is present, what are the 2 molecules of pyruvate broken down into?
Carbon dioxide and water
How much energy is generated in the 2nd stage of aerobic respiration compared to the first stage?
Lots (36 instead of 2, if you want to show off)
What term is used to describe respiration without oxygen being present?
Fermentation
In animals during fermentation, what is the pyruvate broken down into?
Lactate
In plants during fermentation, what is the pyruvate broken down into?
Carbon dioxide and ethanol
How many molecules of ATP are generated by the fermentation pathway? (plants or animals)
2 ATP
Where in the cell does the first stage of respiration take place?
Cytoplasm
