Fill in the blanks using the dropdown menu to describe the process of mitochondrial transport: Protein is Synthesized in the [1]. The newly made precursor protein contains an N-terminal signal sequence (also called a mitochondrial targeting sequence); This sequence is recognized by a receptor protein located on the [2]. The receptor is part of the [3] which initiates translocation across the outer membrane; The protein begins to thread through the TOM channel into the [4]. The receptor–protein–TOM complex moves laterally in the outer membrane until the signal sequence is recognized by the [5] in the inner membrane. The [6] complexes align, allowing the protein to be [7] across both membranes simultaneously. Mitochondrial chaperones inside the matrix (like Hsp70) help pull the protein through and refold it once import is complete; This process requires energy, usually from [8].
