What else can I help you with?
Is the mitochondrial membrane permeable to protons?
Yes, the mitochondrial membrane is permeable to protons.
Can pyruvate cross the mitochondrial membrane?
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
What are facts about integral membrane proteins?
They are usually transmembrane proteins.
What molecule crosses the mitochondrial membrane?
Adenosine triphosphate (ATP) crosses the mitochondrial membrane to provide energy for cellular processes.
In-folds of mitochondrial membrane?
Cristae
What classification of transmembrane protein do channel proteins belong to?
Channel proteins belong to the classification of transmembrane proteins known as integral membrane proteins.
What are the ribbonlike folds on the inner lining of the mitochondrial membrane call?
The ribbon-like folds on the inner lining of the mitochondrial membrane are called cristae.
What type of proteins don't go through the bilayer?
It important that some proteins extend all the way through the bilayer of a plasma membrane. This is to offer protection to the cell and also facilitate the transport of various substances in and out of the cell.
Where is the electron transport chain is found in eukaryotes?
Electron transport occurs in the mitochondria of eukaryotic cells. Specifically, the four protein complexes of the electron transport chain (ETC) exist as transmembrane complexes in the inner membrane of the mitochondria.
Where in the mitochondria is the proteins of the ETC located?
The proteins of the electron transport chain (ETC) are located in the inner mitochondrial membrane. This is where the series of complexes involved in electron transfer and ATP production are situated.
What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.
Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.
