Platelets are used for what?
Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels.
Proteins on the outside of the aids virus bind to what?
proteins on the surface of red blood cells
Proteins in blood that bind to antigens?
Antibodies.
What do signal molecules bind to in cells?
Receptor Proteins
How does the body protect itself after being cut?
When the body is cut, platelets and white blood cells move to the area of the cut. The white blood cells fight infection by producing antibodies that can join with any bacteria that has entered the site. The antibodies will bind to the bacteria and cause them to clump, and other white blood cells will break down this mass. Platelets in the blood help to clot the wound so that it can heal
What are membrane proteins that bind to signals by which cells communicate?
receptor proteins
Can your blood type change when you have a your first child?
No it stays the same from when you were born till the day you die. However, changes can occur to other blood components. Blood is made up of red blood cells, white blood cells, platelets, proteins, lipids, carbohydrates, and complex compounds like polysaccarides and glycoproteins. Some proteins are antibodies made in response to a protein antigen. Because a fetus has proteins that are contributed from both father and mother, babies can have a different blood type than mom. During delivery, mom can be exposed to those different red blood cells and different proteins and start making protein antibodies. The next time she is pregnant, those new antibodies in her blood can attack the fetal red blood cells. This happens, for instance, in Rh positive and negative mismatches. The Rh proteins on the red blood cells of the baby will cause mom (who is Rh negative and doesn't have the proteins) to start making antibodies that bind to the baby's red blood cells and begins to break them apart, causing severe medical problems.
What makes people stop bleeding?
Platelets in the blood will bind together to form a fiber over the wound and clot the blood.
What are attachment proteins?
Attachment proteins anchor the cell membrane in various ways. Some attachment proteins bind the plasma membrane to the network of protein filaments within the cytoplasm called the cytoskeleton. The attachments between plasma membrane proteins and the underlying protein filaments produce the characteristic shapes of animal cells, from the dimpled discs of red blood cells to the elaborate branching of nerve cells. other membrane attachment proteins bind the cell to a matrix of other protein fibers that exist outside the cell. Still other attachment proteins form junctions between adjacent cells. .13 is a wonderful thing. lolz.
What is located in red blood cells and bind to oxygen?
haemoglobin
What are surface cells?
Surface cells are membrane reactors. They store water and serve as integral membrane proteins. These cells bind other cells to each other.
What are plasma proteins that non specifically bind to pathogens?
Nonspecific plasma proteins that bind to pathogens are:Non-phagocytic leucocytes - Basophil. which contains granules of toxic chemicals that can digest foreign microorganisms. They are involved in allergic response.Mast Cells - They are similar to basophils, and contain inflammatory chemicals including histamine and seratonin that cause blood vessels near a wound to constrict.Complement proteins are plasma proteins which have a role in nonspecific and specific defenses.
