For this question, we're looking at the characteristics of antibodies, which i'll abbreviate as ab, and how they work on different types of extracellular and possibly intracellular antigens, which i'll abbreviate as ag.
00:20
So i like to relate our antibodies to, say, like a fork.
00:25
They're responsible for digging in to an antigen, say on a pathogen, and making it easier for certain white blood.
00:35
Cells such as macrophages to engulf that antibody antigen complex so they're basically going to take in that antigen and the antibody and they're going to digest it and eliminate it and this will remove pathogens and foreign antigens from the blood circulation and allow us to fight an infection so for this question they're certainly going to respond to any kind of extracellular substance.
01:19
They're going to respond to a pathogen as long as the antibody is specific enough to attach to the antigens on the pathogen.
01:27
And these can also include, say, toxins.
01:33
Toxins are typically a strand of amino acids to make up a protein, and those proteins would have their harmful effects.
01:41
So our antibodies are also able to bind to toxins because of the protein.
01:46
Proteins function as very good sources for an antibody to buying two...
