trees do not fix N2 from air they fix oxygen with the help of N2 fixing bacteria . so trees do not fix N2
Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.
<h2> Ecological Footprint</h2>
The ecological footprint is an indicator that accounts for human demand on global biological resources. If a person observed his ecological footprint, there will be less environmental problems like carbon emissions, lack of fresh air, global warming and increased environmental pollution would be reduced.
<h3>Impact of ecological footprint</h3>
One of the four categories of ecological footprint can serve as an environmental indicator because the category causes impact on the environment which leads to change in the environment so we can conclude that the category of ecological footprint can serve as an environmental indicator.
