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.
Cell D2 references (points to) cell B2 and cell C2. Both references are relative. 1. Select cell D2, click on the lower right corner of cell D2 and drag it down to cell D5. Cell D3 references cell B3 and cell C3. Cell D4 references cell B4 and cell C4. Cell D5 references cell B5 and cell C5. In other words: each cell references its two neighbors on the left.
