Why are none of the digestive products entering the electron transport chain directly? a) S b) The electron transport chain does not produce ATP. The electron transport chain is too deeply embedded in the mitochondria. c) The electron transport chain only receives electrons arried by reduced electron carrier molecules such as NADH. #192 d) The electron transport chain only receives electrons carried by oxidized electron carrier molecules such as NAD". 4+ Carboye Gyer Fly GP Pyre Gylysis P Odat ACarrow_forward
- How Does Cellular Respiration Extract Energy from Glucose?arrow_forwardHow many ATP are made from one (1) molecule of glucose during anaerobic cellular respiration (AKA fermentation)?arrow_forwardWhy 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.arrow_forward
- 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_forwardb) Place a 'Yes' or a 'No' in the appropriate boxes that correspond to each listed feature of cellular respiration.
