Aerobic respiration begins to function when or are oxidized.

ATP production is greatly increased by oxygen. By combining with hydrogen ions (and accepting electrons) to form water it allows more hydrogen ions to be released from the electron carrier system. During aerobic respiration, oxidation of one molecule of glucose produces 38 ATP molecules (net).

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
