Which type of molecules can pass through the outer membrane of the mitochondria?
Small molecules
What is the main function of Cardiolipins in the mitochondria?
Membrane structure maintenance
Which stage of energy production involves the formation of acetyl CoA from monomers?
Krebs cycle
What is the significance of Cardiolipins in the mitochondria?
Act as carriers of electrons in the electron transport chain
Why is the outer membrane of the mitochondria described as leaky/permeable to small molecules?
To ensure efficient exchange of ions with the cytoplasm
Which component of the mitochondria is responsible for extracting electrons during Krebs cycle?
Mitochondrial matrix
How does oxidative phosphorylation differ from glycolysis in terms of energy production?
Glycolysis generates more ATP per glucose molecule compared to oxidative phosphorylation
Which process directly follows the formation of acetyl CoA from monomers in energy production?
Krebs cycle
What is the role of oxidative phosphorylation in energy production?
Extracting electrons to form energy molecules
How are oxidation and phosphorylation related in the context of oxidative phosphorylation?
They involve the same reactants and products
Which component of the mitochondria plays a crucial role in oxidative phosphorylation?
Cardiolipins
Why is oxidative phosphorylation described as an essential stage in energy production?
It generates energy-rich molecules like ATP
In terms of energy production, what distinguishes oxidative phosphorylation from glycolysis?
The amount of ATP generated per glucose molecule
Which process follows oxidative phosphorylation in the sequence of energy production stages discussed?
Krebs cycle to extract electrons
What is the primary purpose of oxidative phosphorylation?
To produce ATP using electrons extracted in the Krebs cycle
Why is it mentioned that oxidative phosphorylation takes place in the mitochondria?
Because mitochondria have Cardiolipins as phospholipids membranes
How are oxidation and phosphorylation related in the context of oxidative phosphorylation?
Oxidation produces electrons, then phosphorylation uses these to generate ATP
Which stage in the sequence of energy production discussed is directly before oxidative phosphorylation?
Krebs cycle extraction of electrons
What distinguishes oxidative phosphorylation from glycolysis in terms of energy production?
Glycolysis takes place in the cytoplasm, while oxidative phosphorylation occurs in the mitochondria
Which property of mitochondria allows oxidative phosphorylation to take place efficiently?
Leaky outer membrane permeable to small molecules
