The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.
The electron transport chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.
The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water.
The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.
Isotopes of an element are defined has that has same atomic number but different mass number mean they have different number of neutrons
so the statement that best describe a similarity is
<span> same atomic number; different mass number
</span>so correct option is C
hope it helps
The type of carbohydrate that is useful in moving waste through the body system is FIBER. <span> Fiber is a type of carbohydrate that passes through the body undigested.
Fiber is very important to be part of the diet because it</span><span> helps regulate the body’s use of sugars, helps to keep hunger and blood sugar in check.</span>
Children and adults need at least 20 to 30 grams of fiber per day for good health
Dietary fibers are found in fruits, vegetables and whole grains.
