Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane results in the synthesis of ATP during light reaction. Thylakoid membranes contain proteins. These proteins make use of light energy to drive electron transport chains. This generates a chemiosmotic potential across the thylakoid membrane and NADPH. The ATP synthase enzyme uses the chemiosmotic potential to make ATP during photo- phosphorylation.
The greater influx of sodium ions results in what of the membrane?
depolarization
During endocytosis what happens to the pocket in the cell membrane when it breaks loose from the membrane?
Usually, the membrane will burst and let its contents out into the cell membrane and get used up.
Which condition is a tissue mass that results from an overgrowth of upper epithelial cells of the mucosal membrane of the gastrointestinal tract?
Polyp
What do ribosomes synthesize?
Ribosomes synthesize proteins. They are found outside of the cell's nucleus, and they create proteins from amino acids.
Flexible nature of a cell membrane results from?
channel proteins
Is it true the flexible nature of a cell membrane results from its channel proteins?
Yes it is
This results from a defect in membrane proteins that normally function in chloride ion transport?
Cystic Fibrosis
What results in a defect in membrane proteins that normally function in chloride ion transport?
it is cystic fibrosis

Why you use skim milk to block the membrane in western blotting?
The membrane binds proteins unspecifically (it will bind any).Western blotting uses antibodies to probe the proteins bound to the membrane for the one you are testing for. The antibodies bind specifically to a particular protein that you have chosen and contain a label to allow identification of them on the membrane. In this way you can see whether or not the membrane, and therefore the tissue you are testing, contains a particular protein.Antibodies are proteins. This means the antibody would bind anywhere on the membrane, as well as on the protein you're looking for, rendering the results worthless (it will ALWAYS show positive). To stop the antibodies binding to the membrane, so that they only bind to the protein (if it exists) the membrane must be blocked (completely filled with protein) so that there is nowhere on the membrane for the antibody to bind.Since milk contains a generic mix of a relatively high concentration of known proteins, it is used to block the parts of the membrane that don't already have protein on so that the antibodies won't bind there. As it is very cheap and readily available, it is a good source of protein to use. It is unlikely that a Western blot would be needed for any protein that is contained in milk, but if that is the case an alternative mixture can be used.
The greater influx of sodium ions results in what of the membrane?
depolarization
Opening of sodium channels in the membrane of a neuron results in?
depolarization.
What structure in a Cell membrane acts as a door and controls what enters and leaves a Cell?
The main type of gates that regulate the flow of control signal substances into the Cell are called Cell surface receptors.{Active transport of macromolecules into the Cell is not covered here.}Exo-Active transport of the very many different types of biomolecules produced and exported from the Cytoplasm to the Cell's exterior is effected via the [cytoplasmic] Golgi Apparatus. This results in the copious production and use of membrane vesicle producing proteins - after export the membrane fragments are reassembled and the vesicle proteins are recycled.
What transporter in the luminal membrane results in secretion?
Na+ -H+ countertransport
