Pioneering Mars The Basic Chemistry of Photosynthesis
Organisms which can make their own food are called “autotrophs” or “producers” – these undergo photosynthesis (and respiration).
The energy needed for this reaction is harvested from light, absorbed by special photopigments (chief among them is chlorophyll-a)
![Page 3: Pioneering Mars: Turning the Red Planet Green](https://reader031.vdocument.in/reader031/viewer/2022020418/5681631b550346895dd3941e/html5/thumbnails/3.jpg)

Organisms which can make their own food are called “autotrophs” or “producers” – these undergo photosynthesis (and respiration).
Pioneering Mars The Basic Chemistry of Respiration
Organisms which must ingest their food are called “heterotrophs” or “consumers” – these undergo cellular respiration only.
The energy produced from this reaction is stored as ATP, which is the universal energy molecule used to fuel ALL cellular processes (metabolism & LIFE)! +ATP

Pioneering Mars Elements of Sugar: C, H, O
COMPLIMENTARY
Sugars (also known as “carbohydrates”) can only be made naturally from photosynthesis and only require C, H, O (from CO2 & H2O)
Sugars can be stored as an energy reserve, or they can be used in cellular respiration to make ATP
ATP can then be used to power other cellular processes, to make other necessary molecules (like lipids, proteins, and nucleic acids)…

+ATP
Pioneering Mars Elements of Lipid: C, H, O
COMPLIMENTARY
Lipids (fats, oils, and waxes) can be made within the cell using ATP for energy and C, H, O (from respired sugars)

+ATP
Pioneering Mars Elements of Protein: C, H, O, N
COMPLIMENTARY
Lipids (fats, oils, and waxes) can be made within the cell using ATP for energy and C, H, O (from respired sugars)
Proteins can be made by linking amino acids together within the cell using ATP for energy and C, H, O (from respired sugars) and N (from NO3
-, NH4+, and sometimes N2)
Lipids (fats, oils, and waxes) can be made within the cell using ATP for energy and C, H, O (from respired sugars)
