Answer:

Stars form large groupings

Explanation:

A large group of stars that have a common origin and are gravitationally bound for some length of time is called star clusters. Star clusters provide a way to study the ages of stars and stellar evolution. There are two categories of star clusters i.e. galactic clusters, and globular clusters.

Out of the given options, we can say that the correct option is (b) "Stars form large groupings".

NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately
maria [59]

Answer:

Explanation:

NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.

On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.
