The network formed by biochemical reactions. The background gives a schematic impression of how molecules (yellow dots) in a cell are connected by chemical reactions (blue lines), illustrating that together they form an “elastic safety net” that can deal with challenges. An overview of these reactions is given by the interactive “WikiPathways” platform (Available online: https://en.wikipedia.org/wiki/WikiPathways) an open community resource dedicated to collect all interactions among molecules in a cell.
