B snow melting because it turn to solid t liquid which is more energy<span />
<span>Fungi use enzymes to break down the materials on which they are growing . when they absorb digested material , the food would be in the form of a solution in order to enter the hyphal walls of the fungi
. In general, fungi require oxygen to survive, but they are also able to use fermentation when they lack oxygen</span>
Answer:
be scared but don't. act tough.
Answer:
Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.
Explanation:
If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.
Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
Hopefully that helps!let me know if you don't understand anything. also sorry, my ink got smudged on the 3rd question!
