68 Million

‘68 Million’ brings attention to a vital process for all living things on our planet. The production of Adenosine Triphosphate (ATP for short). It is essential that your cells produce ATP. Cells require energy to carry out tasks within your body, all 30 Trillion of them.  ATP acts as an energy transfer molecule for your cell to complete tasks such as transporting proteins, cell division & muscle contraction.


If you did not produce ATP, you would die.


’68 Million’ brings to light the production process of ATP through Aerobic respiration; a process requiring oxygen and producing carbon dioxide & water as waste molecules. The work displays the process across eight sections that act as chapters. Each of them focuses on a specific part of the production line to make ATP. When all the artworks come together, they form ’68 Million’.


In Lewis’s previous artworks such as the Origins series & Carbon Drawings, the focus on understanding how we came to into existence came from looking light-years out into the cosmos across billions of years. Within ’68 Million’ the focus shifts to the opposite end of the scale and the present moment, zooming in on our bodies to attempt to find answers to questions like ‘how are we alive here and now?’


The process of producing ATP has turned into a story within the work. In a similar way, previous artworks by Lewis told the stories of stars billions of years ago. However, the ’68 Million’ story is constantly repeated every day, billions of times just to keep you alive at this very moment.

68 Million - Muscles
Digital Text & Digital Drawing. 2020. 420mm x 594mm & 297mm x 420mm (3).

This work looks at the lactic acid fermentation in your muscle cells to make energy in the form of ATP molecules. ATP is produced by all cells on earth including yours to keep them alive.

"68 Million" focused on cellular respiration which requires oxygen, however some cells don't use oxygen to make ATP like your muscle cells. Instead, they use a process called fermentation. One of those, lactic acid fermentation, is visualized within this artwork and tells its story which is repeated every second of every day inside your own body.

68 Million - Yeast
Digital Text & Digital Drawing. 2020. 420mm x 594mm (2) & 297mm x 420mm (2).

This artwork looks into the alcohol fermentation of cells to make ATP. Another sister artwork (68 Million -Muscles) looks into lactic acid fermentation, with this our end product along with ATP is Ethanol.

This process is very common if your a fan of bread. Yeast Fungi cells use alcohol fermentation. You'll find that your bread (although most of it will be burnt off during baking) will contain trace amounts of Ethanol.
