which of the following woudl decrease the number of atp molecules generated per nadh molecule in the electron transport chain? a. increasing the energy of the electrons nadh transfer to complex I b. reducing the number of protons required by ATP synthase to produce an ATP moelcule c. having nadh transfer its elections to complex III instead of complex I d. increasing the amount of oxygen available to the cell
Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? A)NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. B)They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. C)They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. D)The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. E) They transport protons across the mitochondrial membrane. 14.
In the electron transport chain (ETC), the electrons carried by an NADH molecule have the potential energy to create 2.5 ATP molecules while the electrons carried by an FADH₂ molecule have the potential energy to create only 1.5 ATP molecules. Please explain why this happens.
The above reaction (FADH2 donating its electrons to the electron transport chain) takes place in whichof the following eukaryotic cell locations?A. the mitochondrial matrixB. the thylakoid membrane of chloroplastsC. the chloroplast stromaD. the inner mitochondrial membraneE. the cytoplasm
In biochemistry, the exergonic process ofconverting glucose and oxygen to carbon dioxide and water in aerobic metabolism can be considered the reverse of photosynthesis,in which carbon dioxide and water are converted to glucose andoxygen. Do you expect both processes to be exergonic, both endergonic, or one exergonic and one endergonic? Why? Would youexpect both processes to take place in the same way? Why?
The "high energy electrons" used in the electron transport chain (ETC) of cellular respiration come from glucose. Plants and cyanobacteria produce glucose through photosynthesis. Where does the energy come from to produce glucose with "high energy electrons"?
