In research, examining variables is a major part of a study. There are three main types of variables: continuous variables can take any numerical value and are measured; discrete variables can only take certain numerical values and are counted; and categorical variables involve non-numeric groups or categories.

The receptors then bring the protein to the region containing the translocator proteins. This is actually a complex of proteins. It is called the General Import Pore (GIP) and it facilitates the translocation of the presequence of the protein across the outer membrane. (the GIP is made of Tom40, Tom5, Tom 6, and Tom7).Tom40 appears to be the core element of the pore and forms oligomers.ndeed, the small molecules actually equilibrate between the outer membrane and the cytosol. However, most proteins cannot get into the matrix unless they pass through the inner membrane. This membrane contains cardiolipin which renders it virtually impermeable.
