7. Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? a) They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. b) They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. c) NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. 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.
4. Glycolysis takes place in the: _____ A) nucleus B) lysosome C) cytoplasm D) mitochondria 6. Which of the following pathways directly produces acetyl CoA? _____ A) Hydrolysis of proteins B) glycolysis C) β-oxidation D) Hydrolysis of a polysaccharide E) All of the above
5. Explain the significance of pentose phosphate pathway in your own words
1/How can an inhibitor affect enzyme activity in a cell? 2/Outline glycolysis in terms of phosphorylation and dephosphorylation. 3/ Cells can be broken and then centrifuged to separate organelles, such as mitochondria. If isolated mitchondria were then broken and centrifuged, the membranes would separate from the matrix. Knowing this, develop a hypothesis about the properties of either the matrix or the membranes. Clearly identify what you intend to discover and briefly outline how you would test your hypothesis.
