explain why the tracking of biochemical reactions is difficult
- The tracking of biochemical pathways is difficult because the substances taking part cannot be seen, even with an electron microscope. There are also many intermediate steps in reactions. The cell has therefore appeared like a “black box” with substances entering and leaving, having been transformed or changed. Cells do not function when dead and so methods of study have been limited to those that allow living cells to be studied.
