Partners in crime II – chloroplasts and mitochondria

Chloroplasts are found in the cells of plants that conduct photosynthesis. They absorb sunlight and use it along with water and carbon dioxide gas (CO2) to produce food for the plant.

Mitochondria generate the energy that cells need to function. The energy made by the mitochondria is in the form of a chemical called adenosine triphosphate or ATP.

Mitchell’s equation I

This work belongs to the Mitchell’s dream series, inspired by the Chemiosmotic hypothesis that penetrates all biology. The Nobel prize winning British biochemist Peter Mitchell first published his ideas on the proton motive force in Nature in 1961. The equations here suggest the mitochondrial network.

Erich Gnaiger wrote a short paper inspired by these images. You can read it here.

Golgi and friends in black

These organelles look good together. They are some of the most recognizable cellular components. All can be drawn with a few strong lines that will make them instantly identifiable. The Golgi apparatus packages macromolecules and transports them throughout the cell, in those full vesicles. Mitochondria and endoplasmic reticulum seem to be supervising the operation.
