The final electron acceptor of the electron-transport chain located in the inner mitochondrial membrane is( ). A.ADP B.water C.NADH D.oxygen 点击查看答案 第2题 The protons in a nucleus being equal with the electrons outside, the atom is electrically neutral. 点击查看答案 第3题 Use the...
that the atoms are stripped of their electrons. These free protons then collide and fuse to form a helium atom. The process repeatedly happens, which generates the sun’s enormous energy. Scientists think that this process occurs in other stars too. The process of nuclear fusion is not ...
In this enzyme, FAD is reduced bysuccinateto FADH2and then should be reoxidized to FAD to reduce ubiquinone to ubiquinol (Figure 1 A). From the analysis of the structure of the Complex II:FADH2:covalent system, we hypothesized that proton abstraction from the N1 atom should involve transfer ...
C.Carving dreams in wood. D.Continuing passion on global stage. A proton (质子) is an infinitesimal (无穷小的) part of an atom. Now imagine if you can (and of course you can’t) make smaller one of those protons down to a billionth of its normal size into a space so small that ...
Valence electrons are the electrons that are located in the outermost shell of an atom. In other words, these are the electrons that can be gained or lost during a chemical reaction. Where Are Valence Electrons? Irrespective of the type of chemical bond between atoms, be it an ionic, cova...
For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ...
