ATP synthase!
(The membrane beside it kinda looks like shit though. ) Froglights are to represent ADP binding sites, and are not spatially accurate.
Structure was referenced Cryo-EM model of E. coli ATP synthase from Sobti et. al. Structure 6PQV on PDB
In fact there are remarkable similarities in the way electron flow is coupled to proton translocation in chloroplasts, mitochondria, and purple bacteria (Figure 7.31).

The chemo-chemical transducer that is ATP synthase, which uses the excess chemical potential of some protons to phosphorylate ADP, is actually a chemo-mechanical transducer (the F0 motor) coupled to a mechano-chemical transducer (the F1 motor). See here for some good diagrams and more information about ATP synthase(s).

Molecular embroidery - the process!
The process of creating the light dependent photosynthesis bag
As with all my molecular embroidery projects, an idea gets suggested to me or I take a specific interest in a biochemical pathway, molecule, or cell structure and choose to turn it into a piece of embroidery! Once I have identified a topic of interest, In this case, light-dependent photosynthesis, I research and sketch the elements I will be embroidering. I use my research and preliminary sketches to produce a design, which I transfer to my material - In this case a canvas tote bag. I now get to choose my colour scheme, this is one of my favourite aspects of the project - allowing you to use colours to slightly differentiate the elements of a protein complex but also create something very visually appealing and vibrant! It then takes me close to six hours to embroider the designs and then another to add the detailing of the phospholipid bilayer and the labels. And then finally, I have a finished bag which I can use to carry the weight of supporting all of earth’s biology (much like the light-dependent photosynthesis pathway) :-)

To continue with the ATP synthase posting that seems to be getting a bit of attention, here's a drawing I did in high school art. Please note that I had no formal biology knowledge beyond a single high school intro course when I made this, so the binding site information is false. The structure of binding site AAA1 was retrieved from this paper: Kikkawa, Masahide. (2013). Big steps toward understanding dynein. The Journal of cell biology. 202. 15-23. 10.1083/jcb.201304099. This paper discusses dynein ATP binding sites, not ATP Synthase's ADP binding sites.
Embarassingly, I still have the figure I used to reference the ATP Synthase structure, and from reverse image searching, the source paper gives the correct structure for the binding site: Guo, H., T. Suzuki, and J.L. Rubinstein. 2019. Structure of a bacterial ATP synthase. eLife. 8:e43128. doi:10.7554/eLife.43128. Also it's a bacterial ATP synthase and this is a drawing of the mitochondria. past me had no standards of accuracy smh my head
