Vadim26 [7]3 years ago

Answer:

The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.  

Explanation:

Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.

Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.

Is the sun is the ultimate source for energy on the Earth?
lana66690 [7]

Answer: The given statement is true.

Sun is the ultimate source for energy on the Earth. It is the natural and renewable source of energy on earth as it can easily be renewed and never run off. All living organisms which are present on earth are dependent on food for survival. For this, they become part of the food chain which provides them energy in the form of food. Food chain begins with plants as they are the primary producers in the food chain. They get energy for preparing food from sunlight in the form of light energy.

Moreover, the life forms which existed millions of years ago were dependent on sun for energy. The dead remains of these life forms have provided the non renewable sources of energy like fossil fuels on earth.

Thus, the sun is considered as the ultimate source of energy on the Earth.
