Chemistry and Biology problem, please help!. Please answer both questions I will give a thumb up, thank you!
In 2045, we discover definitive evidence for extraterrestrial life in the form of deep ocean hydrothermal vent communities located beneath the ice sheets of Saturn's moon Enceladus. What metabolic classification is this organism and why? [2 pts] In 2082, we discover definitive spectral biosignatures produced by life on exoplanet TRAPPIST-1e. We believe this form of life uses the infrared light of the star and CO2 gas from the planet's dense atmosphere to fuel its biochemistry. What metabolic classification is this organism and why? [2pts]Explanation / Answer
This microorganisms comes under as chemoautotrophs. Instead of using light energy as a energy source
to fix carbon dioxide into sugar in plants, they harvest chemical energy from the minerals and chemical compounds that from the vents. Hydrogen sulfide, hydrogen gas, ferrous iron and ammonia are the chemical compounds used in the energy provider.
PhotoAutotrophs
Light energy is use to fix carbon dioxide into sugar in plants. The visible region is used from 400-700nm for photosynthesis of plant in earth. They have a pigments like chlorophyll a absorb wavelength at 450-500nm and Anthocyanin or phycoerythrin absorption at 650nm. Infrared wavelength from 700nm to 1mm. So pigment contain in the TRAPPIST planet contains the absorption spection in the range between 700nm to 1mm. So the organism use
this infrared as energy source to fix the CO2 for growth of the organisms.
