C)Bones Surround And Protect The Lungs
Metals conduct electricity and heat, indicating that the electrons are free to move. Metals are malleable, showing that atoms are not in fixed positions but can remain bonded even though they change their positions. In metallic bonding, atoms donate electrons to a pool and all the atoms share in the pool. No compounds are formed, but the atoms are bonded into a network.
The looping of DNA around histone proteins... a. Produces the characteristic helix shape of the DNA b. Allow the room for cellular machinery to reach all genes so they may be transcribed c. Compacts the DNA allowing a large amount of DNA to fit into the cell d. PreventS the DNA from becoming kinked and breaking e.
We generally say that you get 3 ATPs per NADH and 2 per FADH2, so that these carriers produce a total of 30+4 = 34 ATPs..... and the Krebs cycle itself produces 2 GTPs, which are equivalent to 2 more ATPs, for a total of 38.
