Answer:

The structures of the cell responsible for intracellular translocation of cargo are endoplasmic reticulum and transport vesicles.

Explanation:

The endoplasmic reticulum is a tubular structure that provides internal framework to the cell. It also connects nucleus with the plasma membrane. It is a network of membranous tubules, within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis. It serves multiple functions including foding, modification and transport of proteins.

The transport vesicles are small structures within the cell consisting of a fluid enclosed by a lipid bilayer, that have the capacity to hold the cargo. These vesicles will tipically execute cargo loading, budding, transport , binding of the vesicle to a target membrane and the fusion of the vesicle membranes to target membrane.

Answer:

Intracellular cargo is basically the different molecules that need to be transported within the cell and between the different organelles that form this cell. Most commonly, that cargo is formed by proteins. For these proteins to be formed, three different structures must come into play: the nucleus with its genetic material, the ER (endoplasmic reticulum) and the Golgi apparatus, where the process will be refined.

In order for this transportation, and translocation of cargo to happen, molecules like proteins must first be loaded into vesicles, membrane surrounded sacks that are produced by the ER, and which will ensure that these molecules reach their destination and connect with the correct site where they are supposed to go.

Aside from these transport vesicles, the cell counts with another structural component that will further ensure the correct movement of vesicles, and their cargo, to their correct destination; these are called microtubules and the cytoskeleton. Basically, these microtubules and cytoskeleton are strings of protein chains that extend around the cytoplasm and provide both a roadway for vesicles to move, and also structural support to the entire cell. They are also central during cellular division.
