Hello there, mate! Let's solve together:
With the end goal for cells to endure, they require supplements as glucose and minerals in addition to oxygen.
Moreover, they need to discard byproducts. Cells additionally depend on their organelles and dissemination for endurance.
Without oxygen, minerals and the evacuation of side-effects, cells don't endure.
The answer is 99.
Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.
