The only time a cell would be entering the plasma membrane would be with a white blood cell. The process is called phagocytosis, a form of endocytosis.
They are known as killer T cells, which are a type of white blood cell that engulfs and digests foreign proteins/pathogens that enter the body. They work in conjunction with another type of white blood cell called Helper T cells which do the actual targeting of the pathogen/protein.
Transport proteins provide channels for certain solutes to enter and leave the cell.
The plasma membrane consists of a phospholipid bilayer that contains proteins. There are four types of proteins in the plasma membrane - structural protein, receptor protein, transport protein and glycoprotien.
yes
plasma membrane
The nutrients and O do not come from the plasma to the body cells. They came from the red blood cells that deliver them (or so I thought). They then enter the capillaries and give the nutrients and O to the other cells and get the waste products like CO2.
Facillitated diffusion
it enters the vain and the plasma comes out as poo

After being oxygenated in the lungs, the blood enters the left atrium via the pulmonary veins. The left ventricle pumps the oxygenated blood to the rest of the body via the aorta. Blood cells carry oxygen, and the liquid portion of the blood, called plasma, carries the nutrients needed by the cells to perform their life functions. As oxygen enters the body cells, carbon dioxide, as a waste product from cellular respiration, diffuses into the blood, which returns to the right atrium of the heart via the superior and and inferior vena cavae, and is pumped to the lungs to be oxygenated via the right ventricle. As blood travels through the body, nutrients from the plasma enter the cells, and cell waste products enter the plasma. The liver and the kidneys cleanse the plasma portion of the blood, and nutrients are replenished via the small intestine. The plasma portion of the blood also carries hormones throughout the body, which are secreted by endocrine glands into the blood.
potassium ion is attracted by electron pairs of nitrogen present in proteins of RBC.....
Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.
Some viruses are very specific to certain cells. The cell has proteins on it's surface and a virus will use it a docking station to be able to enter the cell. Some cells don't have that protein and the virus can not enter the cell.

Transport proteins provide channels for certain solutes to enter and leave the cell.
