For typical liver mitochondria, the area of the inner membrane is about 5x as large as the outer membrane due to cristae. This ratio is variable and mitochondria from cells that have a greater demand for ATP, such as muscle cells, contain even more cristae.he inner membrane of mitochondria is similar in lipid composition to the membrane of bacteria. This phenomenon can be explained by the endosymbiont hypothesis of the origin of mitochondria as prokaryotes internalized by a eukaryotic host cell.
This is the most widely used type of cell reference in formulas. Relative cell references are basic cell references that adjust and change when copied or when using AutoFill. Example: =SUM(B5:B8), as shown below, changes to =SUM(C5:C8) when copied across to the next cell.
A cell is one of the box-like structures that fill a worksheet and each cell can be located by means of its cell reference - such as A1, F26 or W345 - consisting of the column letter and row number that intersect at the cell's location. Cell references are used in formulas, functions, charts, and other Excel commands. One advantage to using cell references in spreadsheet formulas is that, normally, if the data located in the referenced cells changes, the formula or chart automatically updates to reflect the change.
