What happens next after the ribosome reaches the start codon?
tRNA molecules attach to codons.-apex
Neurotransmitters attach to what molecules in the cell membrane?
Neurotransmitters attach to proteins with sugars attached. The receptors then tell the molecules what to do and where to go in the cell.
Embedded in the phospholipid bilayer?
Protein Molecules
Where in the cell are protein molecules formed?
Protein molecules are formed in the ribosome of the cell/
WHAT organic molecules form the major structural materials of the body?
The organic molecules form proteins for the body.
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
A protein on the surface of HIV can attach to what proteins on the surface of healthy human cells?
Receptor molecules
Do antibodies have a carbohydrate structure?
No, antibodies are proteins. They are Y -shaped protein molecules produced by B cells as a primary immune defense against foreign bodies called antigens.
Which RNA was soluble rna?
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
Which are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells?
Antibodies are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells.
Cell membranes are made up of?
a lipid bilayer - contains protein molecules & carbohydrates often attach themselves to these proteins
What protein carries oxygen in a RBC?
Iron actually helps oxygen molecules attach to red blood cells, so they can be transported through the body.
Antibodies can stick to?
Antibodies stick to any viruses or infections. They don't attack, but they are like homing devices. They track the diseases so white blood cells (the attackers) know where the diseases are.
What happens next after the ribosome reaches the start codon?
tRNA molecules attach to codons.-apex
To what do antibodies respond?
Antibodies are secreted by a special group of white blood cells called lymphocytes. Each type of cell (including bacteria) has a unique protein on its cell membrane - an antigen. If a lymphocyte does not recognise a particular antigen, it will assume that the cell (or bacterium) is foreign and hostile. This is what antibodies respond to - the stimulus as the result of an unfamiliar cell. The antibodies attach to the antigens and kill the cell, or bacterium.
What are molecules that are foreign to your body called.?
Antigens Antibodies neutralize these molecules.
Which nutrient makes up antibodies?
Antibodies aren't made up of nutrients exactly, but are made of protein (different in structure from the protein you eat).
