Design a project that will show information about photosynthesis
and cellular respiration and the connections between the two. Terms
to Include in the Project: (these terms must be in the
project)
Carbon Dioxide (CO2), Oxygen (O2), Glucose (C6H12O6),
Sun/Sunlight/Light, Water (H20), ATP, chloroplast,
mitochondria
Concepts to Include: Function of both processes, location of both
process, reactants of both, products of both, how the two processes
are related in terms of the light dependent, light independent,
glycolysis, citric acid cycle, electron transport chain, what is
ATP and how does it do its job.
Okay, the project is precisely about make some research about these two processes and being able to connect them and explain their connection.
Let us develop the steps in this project and actually answer each section:
1.- What is cellular respiration
- Respiration steps: It has 3 major steps:
Glycolysis: It takes glucose and produces ATP and pyruvate (is tranformed into acetyl CoA with and additional reaction)
Krebs cycle: It takes acetyl CoA and produces GTP, NADH and FADH2
Electron transport chain: It takes FADH2, NADH, ADP and O2 and produces ATP and H2O
- Respiration location: Both cytoplasm and mitochondria
- Respiration reactants: It requires glucose, O2 and ADP
- Respiration products: It releases ATP and H2O
- Requires light? No
2.- What is photosynthesis
- Photosynthesis steps: It has only 2 steps:
Light dependent reactions: It takes H2O and ADP and produces ATP and O2, taking light
Light independent reactions: It takes ATP and CO2 and produces glucose
- Photosynthesis location: Only chloroplast, either in the thylakoid membrane or in the stroma
- Photosynthesis reactants: H2O, ADP and CO2
- Photosynthesis products: ATP and O2
- Requires light? Yes
3.- How are they related?
Well, they can be seen as opposite processes, note that one of them spends glucose while the other produces it, one spends O2 while the other produces it, one spends CO2 while the other produces it, one spends water while the other produces it. These work as complementary processes.
Note that you can actually state something not widely known about water with this knowledge. It is normally said that water is in a cycle where it is never destroyed, only transformed and moving acros different places in the plante, but that is lie. You can see how water is created in cellular respiration, and destroyed in photosynthesis.
