Amandine and Lara Flashcards
Respiration
Where does Glycolysis take place?
Cytoplasm of cells
Where does the Krebs Cycle take place?
Mitochondria Matrix
Which hydrogen acceptors are formed in the Krebs cycle?
Reduced NAD and reduced FAD
How does glucose change to 2 triose phosphate?
It is phosphorylated by adding 2 phosphates from 2 ATP (creating 2 ADP)
What is the final electron acceptor? Where is it?
Oxygen which binds to hydrogen to form water. At the end of the ETC, in inner mitochondrial membrane.
What is chemiosmosis?
Chemiosmosis is the movement of hydrogen ions across the electron carriers/ ETC and then down a electrochemical gradient through ATPase.
How is the citric acid produced?
The acetyl coenzyme A (2C) is joined together with a 4C molecule
Where does oxidative phosphorylation take place?
Across the inner mitochondria membrane
Where does the link reaction take place?
Mitochondrial matrix
What is the name of the 4C in the Krebs cycle?
Oxaloacetate
What happens during the electron transport chain reaction?
Electrons move from a higher energy level to a lower energy level.
How do the hydrogen ions move in the electron transport chain?
The ions are pumped from the matrix to the intermembrane space. From a lower to a higher concentration using energy from the electron being transferred.
How is ATP formed in oxidative phosphotylation?
Through chemiosmosis, the hydrogen ions move through the ATPase providing energy for ADP + Pi to bind together forming ATP.
How many ATPs are produced from 1 glucose molecule?
32-38 if enough oxygen present
What is the overall reaction of aerobic respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O
