A is the answer to this question. The electric transport chain will start with NADH+FADH2. The output will be 34 or 36 ATP. The electron transport chain is known to be important because this is the process that occurs during a redox reaction. What happens is that the carriers will provide not only electrons but also protons to electron carrier proteins. If this would not take place, certain processes will not be possible.

There are different living organisms that would have to go through this process otherwise, this can become a problem in the long run. In most electron transport chains, the final acceptor is usually oxygen.

The answer to this is letter A. The electron transport chain is known to be a complicated process that electrons go through to ensure that the chemical bonds that will be formed are strong. The input of the electron transport chain is NADH+FADH2. The output will be 34 or 36 ATP. There are moments when the electron transport chain is effective in getting energy from certain situations.

For example, this occurs during photosynthesis when sunlight reaches the plant. There are various molecules that are made to provide and accept the electrons in order to achieve the needed reaction. Take note that some electron transport chain reactions may not go as planned and it may lead to oxidative stress.

10 NADH (2 from Glycolysis, 2 from Pyruvate oxidation, and 6 from Citric Acid Cycle), 2 FADH2 (From Citric Acid Cycle), and 4 ATP (From Glycolysis and Citric Acid Cycle).
