Energy Release/ Respiration Flashcards
What is the structure of 1 molecule of ATP?
Adenosine - Pi - Pi - Pi
What is the related molecule ATP is made from and what is its structure?
ADP
Adenosine- Pi - Pi
What is the equation for the formation of ATP?
ADP + Pi + energy = ATP
What is respiration?
The process which energy is released during the breakdown of glucose.
The energy released by respiration is used in the formation of ATP.
What is aerobic respiration?
When oxygen is available
During aerobic respiration oxygen is used up by chemical steps in the breakdown of glucose.
What is the energy source in cells?
ATP
Adenosine triphosphate
Give examples of the use of ATP in a cell
Muscle contraction
Cell division
Protein synthesis
What are the three stages of aerobic respiration?
Glycolysis
Keeps cycle
Cytochrome system
Where does glycolysis occur?
In the cytoplasm
Where does the Krebs cycle occur?
In the matrix of the mitochodria
Where does the cytochrome system occur?
In the cristae of the mitochondria
What does aerobic respiration use up and produce? (Summary)
Uses up glucose and oxygen
Produces carbon dioxide, water and 38 ATP
How much ATP does glycolysis produce?
2 molecules
How much ATP does the Krebs cycle produce?
2 molecules
How much ATP does the cytochrome system produce?
34 ATP
