Respiration and Photosynthesis
Cellular Respiration and Photosynthesis Are Almost Mirror Images
Both photosynthesis and cellular respiration involve energy.
The
chemical equation for photosynthesis
is 6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2.
The
chemical equation for cellular respiration
is C6H12O6 + 6O2 --> 6C 2 + 6H2O + ATP
Materials are the same, but the processes are reversed.
Both consist of two main stages;
In photosynthesis, solar energy is absorbed, while in cellular respiration energy is released in the form of ATP
Both photosynthesis and cellular respiration have an electron transport chain that works the same way in both processes.
Plants, algae, and some bacteria absorb sunlight primarily using the green pigments
chlorophyll a and b.
These pigments are found in organelles called
chloroplasts.
Sugar, primarily glucose, is made using carbon dioxide and water. Energy is trapped in the bonds of the sugar molecule. Oxygen gas is given off as a waste product. Cellular respiration then breaks up the sugar and uses oxygen to produce energy in the form of ATP. Carbon dioxide gas is produced as a waste product. This process takes place in organelles called
mitochondria.
Similarities and Diffrences
Energy flow (with name of organelle involved)
(Cellular Respiration)
Energy, in the form of ATP, is released by the mitochondria
(Photosynthesis)
Energy from the sun is captured by chlorophyll in the chloroplast. Sugars are made, which store the energy in the bonds of the molecules.
Chemical equation
6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2
C6H12O6 + 6O2 -->6CO2 + 6H2O + ATP
Description of organelle in which the process takes place
Chloroplast: has both inner and outer membranes. There is also an inner fluid chamber.
Mitochondria: has both inner and outer membrane in which respiration takes place. There is also an inner fluid chamber.
Number of main stages and their names.
2 main stages
Light-dependent reactions
Light-independent reactions
2 main stages:
Krebs cycle
Electron transport chain
Photosynthesis consists of the light-dependent reactions followed by the light-independent reactions.
Cellular respiration is made up of the Krebs cycle and the electron transport chain.
