The link reaction and Krebs cycle occur in the cytoplasm of prokaryotes in the same way that they occur in the mitochondria of eukaryotes. However, a concentration gradient across a membrane is a requirement of the electron transport chain. Propose an alternative site for that phase of cellular respiration in prokaryotic cells.
what are those electrons used as an output of TCA
Would free energy be required for the hydrogen ions to move from the intermembrane space to the mitochondrial matrix?
What molecules carry the high potential energy electrons used to pump hydrogen ions across the inner mitochondrial membrane?
What is the name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane?
Is the release of an electron from an electron acceptor molecule oxidation or reduction?
What molecule is the final electron acceptor after the electron has moved through the electron transport chain?
Is any ATP produced in the electron transport chain?
The flow of hydrogen ions through the protein channel provides free energy to do work. What process in chemiosmosis requires energy?
What compound is formed as a final product of the electron transport chain?
When electrons are released from the electron acceptor molecules, what else is produced?
Is any ATP used in the electron transport chain?
