Connecting Respiration and Photosynthesis
Photosynthesis removes the carbon dioxide from out atmosphere (CO2 is an input)
The products of one process are used as the reactants for the other.
Both show the cycle of the formation of ATP/ ADP + P (or ADP) energy (phosphorylation)
Photosynthesis:
Inputs; water, sunlight, carbon dioxide (CO2)
outputs; glucose and oxygen (O2)
- glucose as an output is food for the organism (ex. plant), yet remains unused as ATP is mainly used as the organism's source of energy.
Cellular Respiration:
Inputs; glucose and oxygen (O2)
Outputs; water, ATP energy, carbon dioxide (CO2)
Photosynthesis makes the glucose that is used in cellular respiration to make ATP
The output of cellular respiration is the input of photosynthesis
The glucose is then turned back into carbon dioxide, which is used in photosynthesis
Cellular respiration restores it (CO2 is an output)
Cellular Respiration -> uses the released oxygen to release energy from food
Photosynthesis -> releases oxygen into the atmosphere
All living things must either use photosynthesis or cellular respiration but they are dependent on one another.
Both produce some form of energy.
The waste product of photosynthesis is used in cellular respiration and the waste product of cellular respiration is used for fuel and photosynthesis
Connection between chemosynthesis and cellular respiration

Chemosynthesis; the usage of oxidation (using inorganic compounds such as hydrogen, ex. hydrogen sulfide, gas, carbon dioxide) to convert a carbon molecule(s) and create energy.
All chemosynthetic organisms use energy released by chemical reactions to make a sugar
Hydrogen sulfide, molecular hydrogen, ammonia, manganese, or iron are all possible inputs, as long as they are hydrogen compounds.
Bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide
Photosynthesis and chemosynthesis are both processes by which organisms produce food; photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy.
