Question

Can you tell me the steps Carbon Dioxide goes through in Photosynthesis and Cellular Respiration?

Answer 1

During the day,

Plants take i Carbon dioxide through the Stomata during gaseous exchange, diffusing from a higher concentration at the atmosphere to a lower concentration in the leaf of a plant as Carbon Dioxide has been used up previously. Carbon Dioxide along with light energy and water is fixed into Glucose and Oxygen.

\[6CO _{2}+6H _{2}O \rightarrow C _{6}H _{12}O _{6}+O _{2}\]
Conditions are :
Light Energy and Chlorophyll

Glucose is being used for the plants during Cellular Respiration which Occurs all day and night 24/7. Oxygen diffuses into the leaf consistently to replace those used up for cellular respiration. Carbon dioxide in this case diffuses out of the leaf as a by-product

C6H12O6 + 6O2 ----> 6CO2 + 6H2O + Energy


This is just a Brief Explanation. We can go further in-depth if you would like.

Answer 2

Oh and Excess glucose is stored in leaves as starch :)

Answer 3

this is great! :D but do you think you can tell me specifically what CO2 does once its in the plant?

Answer 4

If it fulfils the conditions and there is lack of glucose the plant will start to photosynthesize ?

Answer 6

now that i look at this i guess my main question is that i dont really understand the calvin cycle, do you think you can clarify for me?

Answer 7

Which part of the Calvin Cycle do you not understand ?

Answer 8

how about i tell you what exactly the assignment is so you understand what im trying to accomplish here?

Answer 9

ok

Answer 10

youre supposed to write from the point of view from either CO2, Oxygen, Glucose, or H2O (i chose CO2) going through the process of Photosynthesis and Cellular Respiration. So i have to pretend to be Carbon Dioxide and explain myself going though all these processes. Thats why i need sort of like a numbered list of what CO2 actually does in them.

Answer 11

and im kind of lost of what carbon dioxide does during the calvin cycle. after that it obviously just turns into food and then back out into the atmosphere as CO2 again, right?

Answer 12

Found a piece of information on Calvin Cycle : http://www.bio.umass.edu/biology/conn.river/calvin.html

Answer 13

thanks :D
