Answer:

The correct answer is: the antibodies' shape.

Explanation:

<u>Antibodies are proteins called immunoglobulins that serve the immune system by responding to a specific antigen and generating the proper counter to fight it. </u>

Each antibody consists of four polypeptides that form a "Y" shaped molecule. The Y shape is given by two heavy chains and two light chains.

<u>The tips of the Y are composed of 110-130 amino acids that vary greatly among other antibodies. This gives the antibody its </u><u>specificity</u><u>.</u>

  • At the point when one phosphate bunch is expelled by breaking a <em>phosphoanhydride bond in a procedure called hydrolysis,</em> <em>vitality is discharged, and ATP is changed over to adenosine diphosphate (ADP).  </em>
  • <em>ATP works as the vitality cash for cells.</em> It permits the cell to store vitality quickly and transport it inside the cell to help endergonic concoction reactions.
  • As ATP is utilized for vitality, a phosphate gathering or two are withdrawn, and either ADP or AMP is created.
