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.
When you copy this formula from cell B2 to cell C2, the cells referenced in the formula also move over one cell. The formula which was =A2*B1 now becomes =C1*B2. This is a feature designed into Microsoft Excel and is called a relative formula reference. As you copy a formula, the cell references in the formula also move a corresponding number of cells across and down. There are times when you do not want Excel to exhibit this behavior and the current case is one of those.
