Where in the mitochondria does the electron transport system occur?
Inner mitochondrial membrane.
What is the purpose of embedding the electron transport chain in the membrane of an organism?
The mitochondrial membrane is impermeable to the H+ ions.
The transfer of high-energy electrons down the electron transport chain causes what to be transported across the mitochondrial membrane?
The electron movement causes H+ ions to be transported to the cystolic side of the mitochondrial membrane from the mitochondial matrix. This creates the electrochemical gradient that is used to generate chemical energy (ATP from ADP)
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane used to make?
electron transport chain
The electron transport chains of cellular respiration are located?
This depends on whether you are a eukaryote, bacteria or archaea. In eukaryotes, the electron transport chain components are on the mitochondrial membrane.In bacteria and archaea, since there are no membrane-enclosed compartments, they are on the cellular membrane.
What is a molecules in the mitochondrial inner membrane that catalyzed the the production of ATP?
CHECK
Where does the electron transport chain take place in the mitochondria?
The electron transport chain takes place in the inner mitochondrial membrane.
Where does the electron transport chain take place during cellular respiration?
In the inner mitochondrial membrane- Cristae.
Where in the mitochondria is the proteins of the ETC located?
The Electron Transport Chain is located in the inner mitochondrial membrane and the thylakoid membrane in chloroplasts.
Which term refers to the collections of electron carriers that are embedded in the inner mitochondrial membrane and in the thylakoid membrane?
The electron transport chain.
Where is the site of the electron transport system?
mitochondrial inner membrane (cristae)
Where does the electron transport occur in eukaryotes cells?
Inner mitochondrial membrane
Where in the mitochondria does the electron transport system occur?
Inner mitochondrial membrane.
What is the purpose of embedding the electron transport chain in the membrane of an organism?
The mitochondrial membrane is impermeable to the H+ ions.
Where do the reactants of the electron transport chain occur?
In the inner membrane of the mitochondrial organelle.
Electron transport chain pumps hydrogen ions to what space?
mitochondria inner membrane
Why are the components of the electron transport chain embedded in the inner mitochondrial membrane rather than floating freely in the cytoplasm of mitochondrial matrix?
to generate and maintain the protein gradient essential for ATP production
