Labelled carbon enters living system through photosynthesis alongwith normal cabon in the form of carbohydrates. When we eat them, our body converts them in glycoproteins found in our muscles and all parts of body.
The quick and dirty answer:
Carbon atoms in the atmosphere are in the form of CO2 (for the most part)
Plants convert CO2 into simple sugars
Humans eat the plants and use the sugars for fuel and building tissues like muscle
A protein Molecule
The type of molecule that is an enzyme is a protein molecule.
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
The molecule that can bind to a receptor protein is called a ligand.
Depends greatly on the salt or the protein. There is not one salt or one protein molecule, so you will have to be more specific.
A protein.
Protien!!! :)
it is a water channel, a protein molecule
Protein.
its an enzyme enzymes are a type of protein
Trypsin is an enzyme that is produced in the pancreas. After the human pancreas binds to a molecule of protein, auto catalysis occurs to a molecule of trypsin.
