Is mitochondrial ATP synthase an integral membrane protein?
Step by step
Solved in 2 steps
- Only 37 of the proteins in mitochondria are encoded by the mitochondrial DNA. The other proteins are encoded in nuclear DNA, then translated and transported to the mitochondria. Describe one unique feature of protein transport across mitochondrial membranes.Would mitochondrial transmembrane transport of a protein bound for the mitochondria intramembrane space involve TOM, TIM or both?Describe the molecular mechanisms of mitochondrial ATP synthesis.
- Using the answer code on the right, indicate which form of energy production is being described: 1. takes place in the mitochondrial matrix 2. produces H2O as a by-product 3. results in a rich yield of ATP 4. takes place in the cytosol 5. processes acetyl-CoA 6. takes place in the mitochondrial innermembrane cristae 7. converts glucose into two pyruvate molecules 8. uses molecular oxygen 9. accomplished by the electron transport system and ATP synthase (a) glycolysis (b) citric acid cycle (c) oxidative phosphorylationWould mitochondrial transmembrane transport of a protein bound for the mitochondrial intermembrane space involve TOM, TIM or both?What are two examples of cytosolic chaperone proteins involved in mitochondrial protein import? Upon binding the synthesized protein how does it prevent protein folding?
- Describe the source or sources of energy needed for unidirectional translocation across the membrane in (a) cotranslational translocation into the endoplasmic reticulum (ER); (b) post-translational translocation into the ER; (c) translocation into the mitochondrial matrix.Why is IMPDH in the mitochondria?Which directions across the mitochondria must H+, ATP, ADP, and Pi travel during active mitochondrial ATP synthesis?
- If the mitochondrial inner membrane potential was depolarized (switched from + to -), what effect would this have on protein translocation into the mitochondria? Explain.Does the Tom complex take/require energy? What kind of proteins do the Tom complex bring into the mitochondria?How are proteins normally transported into the mitochondrial matrix, if they were originally synthesized on ribosomes present in the cytosol (not on the rough endoplasmic reticulum)? they are packaged into vesicles with v-SNARES for fusion with their target organelles they can pass freely through large pores in the inner mitochondrial membrane they are secreted by the golgi, captured by receptors, and absorbed by endosomes they must pass through the nuclear envelope by means of nuclear pores they are unfolded in the translocation channel, then refolded by chaperones
