The import of proteins into mitochondria requires energy in the form of ATP for their [____] and of mitochondria that are energized, with an electrochemical gradient. The imported proteins must be synthesized on [____] ribosomes as they are bound to requisite [____]. Protein import itself requires that the protein have an N-terminal targeting sequence that folds into an [____] for interaction with the import receptor on the outer mitochondrial membrane. The translocase of the outer membrane (TOM) complex consists of...

All mammalian cells maintain the resting membrane potential across the plasma membrane. Neurons and muscle cells are capable of generating the action potential to communicate with each other. Below is a diagram showing a temporal change of the membrane potential in axon. Explain how such membrane potential is generated and/or maintained in each stage (1-3). Make sure to identify key membrane proteins and the movement of ion(s) through these membrane proteins in each stage. Calculate the membrane potential at the...

Which of the following statements describing the import of proteins into the nucleus is correct? Answers A-D A Transport into the nucleus requires the activity of a G protein. B The receptor for nuclear proteins is found in the cytosol and travels into the nucleus with the protein being transported o С Proteins destined for the nucleus are transported in a fully-folded conformation. D These statements are all correct. o You are interested in a water-soluble protein that functions within...

Please answer letter B!
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...
