Protein transport into the ER occurs via _____ translocation, whereas protein transport into the mitochondria occurs via ______ translocation.
Homework Answers
Answer
Protein transport into the ER occurs via Sec61 cotranslational translocation, whereas protein transport into the mitochondria occurs via TIM complexes, posttranslational translocation.

Choose the correct statement about transport of ATP from mitochondria. Transport of ATP occurs without energy expense. ATP passes freely through the inner mitochondrial membrane. ATP has the same negative charge as ADP. Transport of ATP is not coupled with ADP. ATP is moved across the inner mitochondrial membrane by specific 30 kDa transport protein.

Select all of the examples of protein translocation across a membrane below that directly require the hydrolysis of ATP to drive the process movement of a protein into the mitochondrial matrix from the cytosol recycling of the Pex5 peroxisomal receptor to a state that will bind PTS1-containing proteins in the cytosol transport of NLS-containing proteins into the nucleus by importin co-translational translocation of proteins into the ER lumen can be multiple answers

1. (1.5 pts) Entering the ER: Translocation of proteins across the membrane of the ER is usually studied using microsomes (vesicles made from rough endoplasmic reticulum. Microsomes of the rough ER carry ribosomes attached to their outer surface. Translocation of proteins across the microsomal membrane can be assessed by several experimental criteria: (1) the newly synthesized protein is protected from added proteases, but not when detergents are present to solubilize the protecting lipid bilayer; (2) the...

Cam1 is a protein involved in ER to Golgi transport, and is located on the Golgi membrane. When wild-type Hip-GFP is expressed in wild-type yeast cells and in Cam1 mutant cells (or cells without functional Cam1), the following results are obtained. (+ indicates fluorescence is present, - indicates fluorescence is absent) Cell Type Localization & intensity of GFP fluorescence ER membrane Vesicle membrane Golgi membrane Wild-type + + + Cam1 mutant + +++ - More vesicles with Hip-GFP are seen...

1) What determines whether a protein will be translated in the cytosol or on the ER surface? 2) What is the difference between post-translational ER import and co-translational translocation? 3) Can you explain the steps that ensure a protein is translated in conjunction with the ER? ( Including names. What is the SRP/SRP receptor/translocon, etc, and how do they help?)

In mitochondria, a proton gradient is established by the movement of electrons through the electron transport chain. Protons are moved to the intermembrane space against the concentration gradient and the flow back to the matrix via facilitated diffusion using the ATP synthase. Describe how this proton flow contributes to ATP synthesis and the role played by aspartic acid in this process.
