We have to know the type of reaction involves in building a large protein from amino acid.
The reaction involves is condensation reaction.
Protein is made up of amino acids. Amino acid is the building block of proteins. Amino acids combine by condensation reaction and forms polypeptide linkages (-CONH-) after loss of small molecules like water.
Answer: If you change the number of electrons in an atom it will become an ion
Explanation: When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.
Seven electrons. The atomic number of a element is also the amount of protons and electrons it has.
