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.

How do fermentation and anaerobic respiration enable cells to produce ATP without the use of oxygen?
Indicate whether the statement is true for aerobic respiration, photosynthesis or both:
The transfer of electrons via redox reactions is coupled to the movement of protons from one side of the membrane to the other
a)Aerobic Respiration
b)Photosynthesis
c)Both

- For cells that are capable of aerobic cellular respiration and fermentation, such as yeast cells, one pathway may be favored over the other in certain circumstances. Which of the following accurately describes an advantage of the fermentation pathway, when compared to aerobic cellular respiration? A) Fermentation is quicker because it does not involve glycolysis B)Fermentation can occur in the absence of oxygen (O2) C)Fermentation generates a higher amoung of ATP per glucose substrate D)Fermentation is less costly for the cell because it does not involve enzymes 10.arrow_forwardWhat is the purpose of respiration?
