<h3><u>Answer;</u></h3>
B. Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor.
<h3><u>Explanation</u>;</h3>
- NADH and FADH2 are two important electron carriers in the cellular respiration process.
- NADH is a high-energy electron carrier that is reduced during glycolysis, pyruvate processing, and the citric acid cycle, and which carries electrons to the electron transport system.
- The electron transport chain passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers.
<span>When the hexene is treated with an excess of hydrogen gas and a platinum catalyst, the product formed is
hexane.
Hexene is an unsaturated hydrocarbon. Hexene when treated with H2 gas, in presence with Pt catalyst, the double bond is broken. This results in generation of saturated hydrocarbon i.e. hexane. </span>
<span>BrI molecule is made of Bromine and Iodine. The polarity depends on the electronegativity of Bromine and Iodine. The one which has more electronegativity value shall be the negative pole
Br: 2.96
I: 2.66
Hence the negative pole shall be Bromine.</span>
The answer is A) Water has surface tension.
This is the correct answer because water allows animals and really light items to rest upon the top of the water.
Hope This Helps! If you could mark me as the brainiest answer, that would be amazing. I want others to read this answer and know it is accurate. If you need help with another question, just ask. :)
