An antigen is a molecule that is located on viruses, bacteria, cancer cells, and other pathogens. An antigen is very specific to each pathogen. A flu antigen is different from a pneumonia antigen, and an HIV antigen is different from a measles antigen. I like to think of an antigen as a lock, understanding that all locks are different and very specific. The key that fits these antigen locks is called an antibody. Antibodiesare found on certain types of white blood cells that our body produces. Antibody-producing white blood cells are called lymphocytes. Lymphocytes travel around our body and attach antibodies to pathogen antigens. Once an antigen has an antibody attached to it, phagocytes attack the pathogen, engulf it, and kill it. Sometimes the antibody disables the pathogen so that it cannot reproduce or release toxins.

What is the potential energy surface of a molecule?
potential energy of a molecule is equivelent to the energy of the molecule in a fusion state
How can you say that a carbon in molecule is chiral?
Chiral carbon is the carbon which is connected to four different groups in a molecule.
A DNA molecule consists of how many stands?
The DNA molecule has two strands connected by a sugar phosphate backbone.
When the human body mobilizes its defenses against a pathogen the body recognizes the pathogens?
Surface Proteins
What is the organic molecule of the waxy surface on plants?
Carbohydrates
What molecule is connected to the Z disc?
Actin
What molecule is connected to the Z line?
titin
What is the potential energy surface of a molecule?
potential energy of a molecule is equivelent to the energy of the molecule in a fusion state
Which part of a phospholipid molecule contains a phosphate group?
Phospholipid molecule is actually almost similar to a lipid molecule. It is a alcohol connected to 2 fatty acids and a phosphate group.(In lipids, its connected to 3 fatty acids)
How can you say that a carbon in molecule is chiral?
Chiral carbon is the carbon which is connected to four different groups in a molecule.
What happens if a molecule with a high kinetic energy happenes to be close to the liquid's surface?
Then that molecule will escape the surface of the liquid and become a molecule of gas. This is the process by which water slowly evaporates even when not heated.
How are the strands of the DNA molecule connected with one onother?
spirally
What is a Whole water molecule?
One water molecule is a combination of one Oxygen molecule and 2 Hydrogen molecules connected through a covalent bond.
A DNA molecule consists of how many stands?
The DNA molecule has two strands connected by a sugar phosphate backbone.
When the human body mobilizes its defenses against a pathogen the body recognizes the pathogens?
Surface Proteins
Process of immunity?
The process of immunity is to produce specific antibodies that bind to antigens on the surface of pathogens. =]
Is carbon a molecule or a atom?
Carbon is an element. Elements are atoms at its simplest. A molecule is a collection of atoms connected by an electric charge.
