Oxygen is the final electron acceptor in the electron transport chain in aerobic respiration The electron transport chain of the mitochondria is the means by which electrons are removed from reduced carrier NADH and transferred to oxygen to yield water. In the cytochrome oxidase complex of the electron transport chain, four electrons interact with a molecule of oxygen and eight hydrogen ions. The four electrons, four of the hydrogen ions and the molecule oxygen are used to form water molecules. In anaerobic respiration the final electron acceptor can be of many types such as Ferric iron which is used by denitrifying bacteria

A person who has very toned muscles likely has.... A.extra nerve cells. B. lots of digestive enzymes. C.tightly packed myofibril
Zarrin [17]

We can confirm that a person with very toned muscles likely has tightly packed myofibrils.

<h3>What are myofibrils?</h3>

These fibers are the protein filaments that cause contractions in the structure of the muscle. Weight training tones muscles by increasing the number of myofibrils in a sarcomere, thus increasing its capacity to produce force.

Therefore, we can confirm that a person with very toned muscles likely has tightly packed myofibrils.

Which of the following is not a function of protein?
masha68 [24]
C. Insulating the body

Insulating the body is not a function of a protein.

Lipids are macromolecules which provide insulation. 
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.
