Cellular Respiration
Question | Answer |
---|---|
What is the direction of the proton transfer by electron transport chain complexes I, III and IV | From matrix to intermembrane space of mitochondria |
What is the direction of the proton transfer by electron transport chain complex II | Complex II does not contain a proton pump element and thus does not perform pumping of protons |
The number of mitochondria in a cell may vary mainly depending on: | the metabolic needs of the cell |
What is the role of NAD+ in the process of cellular respiration | It functions as an electron carrier |
Citric Acid (Krebs) Cycle occurs in: | Matrix of mitochondria |
F1F0 ATP Synthase is an example of molecular turbine. It utilizes _______ to perform the synthesis of ATP | the flow of protons across the inner mitochondrial membrane |
Oxidative phosphorylation occurs in the inner mitochondrial membrane | True |
The advantage to the cell of the gradual oxidation of glucose during cellular respiration compared with its combustion to CO2 and H2O in a single step is that ________________. | energy can be extracted in small usable amounts |
Glycolysis produces bulk of ATP in a eukaryotic cell under aerobic conditions | False |
Which of the following is (are) NOT a product of glycolysis: | CO2 |
Which of these terms or processes is NOT associated with mitochondria? | Glycolysis |
During glycolysis, the steps between glucose and formation of the triosephosphates _______ | consume two molecules of ATP |
In mitochondria, exergonic redox reactions | provide the energy to establish the proton gradient |
Where does glycolysis occur? | Cytosol (cytoplasm) |
