Produces energy in the form of ATP atp using Temperature temperature gradients in the environment. Prokaryotic form of the more efficient Thermoplast.

Speculative organelle not found in real life. Unavailable in games with LAWK (Life As We Know it) turned on.

It is a grouping of membranous compartments containing thermosensitive enzymes. The enzymes are able to use the energy of rising Temperature temperature in their surroundings to produce ATP atp in a process called thermosynthesis.

Requirements

Thermosynthase only appears in games with "LAWK" turned off in game settings. If organelle unlocks are enabled in game settings, the organelle will be unlocked once the following condition has been met for the player cell:

  • Is in a patch with at least 50 °C Temperature temperature.

Processes

Bacterial Thermosynthesis: Temperature temperature increaseATP atp

Generates energy from increasing Temperature temperature. The thermosensitive enzymes change shape as the Temperature temperature rises, allowing the recycling of ADP into ATP atp. As the cell cools, the enzymes return to their previous shape, allowing the process to repeat. Less efficient form of the Thermosynthesis present in Thermoplasts. The rate of its ATP atp production scales with Temperature temperature delta.

Modifications

No modifications.

Effects

Enables thermal vision, which can be toggled on and off. This overlays the relative temperature of the water onto the screen, with hotter areas looking more red.

Upgrades

No upgrades.

Strategy

Probably the most mobile form of autotrophy, Thermosynthesis requires almost constant movement. You need to go from colder areas to hotter ones and back again. After the cell's temperature has stopped increasing, ATP atp production drops to zero. It is best to activate thermal vision to see the hot and cold areas around your cell, to most effectively steer through them. Thermosynthase is much more effective in much hotter patches, and so is best used in the Volcanic Vents.

Because Thermosynthase's ATP atp production will stop frequently, it is important to have a second energy source, or else you will take continual damage from lack of ATP atp.

More efficient still is the Thermoplast, available once a cell evolves a Nucleus. Like all prokaryotic organelles with eukaryotic counterparts, we recommend replacing Thermosynthase with Thermoplasts when possible.

Scientific Background

Thermosynthase is a fictional enzyme, but the process of thermosynthesis, while theoretical, is generally regarded as biologically plausible.

Thermosynthesis was first proposed by Anthonie Muller in a 1983 paper "Thermoelectric energy conversion could be an energy source of living organisms" (Physics Letters A, vol. 96, Issue 6, p. 319-321). Muller even suggested that thermosynthesis could have been a precursor to the earliest (sulfur-based) photosynthesis (see link: A Search For Thermosynthesis: Starvation Survival In Thermally Cycled Bacteria).

In earlier versions of Thrive this organelle produced ATP directly, however due to game balancing reasons it now produces glucose, but there's no explanation for where the carbon would come from for that. So that's one more Thrive sin against realism. This might get fixed in the far future if someone volunteers to implement an organelle that would turn ATP to glucose for longer term storage.
