What is the relationship between cell respieration and photosynthesis?

Question

What is the relationship between cell respieration and photosynthesis? What are the chemical equations involved in this process?

Thanks.

Answer 1

THE MOST IMPORTANT REACTION ON EARTH.

THE BASIS OF ALL LIFE.

Its when a molecule of chlorophyll traps a photon of light energy........as if by magic.....the rest follows, till we get potatoes.

Having looked into it....I dont think we understand even the tiniest bit of the given models .....for instance why  and how does magnesium in chlorophyll help to trap a photon of light , magically converting it into energy?  We have the same molecule but magnesium is replaced by iron.....haemoglobin, we cant trap that photon....instead it carries oxygen to keep us alive.

Answer 2

Here's a few ways of looking at

[1]

photosynthesis:  CO2 --> glucose

cellular respiration:  glucose --> CO2

------------------------

DESCRIPTIVE SUMMARY:

Photosynthesis produces oxygen and glucose, which will be used in the set of reactions called cellular respiration. Photosynthesis consumes CO2 and gives off O2, while (aerobic) cellular respiration consumes O2 and gives off CO2, making these two a perfect complement, with the net effect being turning sunlight into the potential energy in the chemical bonds that comprise plants and animals.

[2]

PHOTOSYNTHESIS: CO2 + energy + water => glucose + O2

RESPIRATION: glucose + O2 => CO2 + energy + water

(They are mirror images of one another)

------------------------------

[3] PHOTOSYNTHESIS

6 CO2 (gas) + 6 H2O +  -->   C6H12O6 + 6 O2 (gas)

carbon dioxide gas + water -->  glucose + oxygen gas

CELLULAR RESPIRATION

C6H12O6  + 6O2 (gas) --> 6CO2 (gas) + 6H2O

glucose + oxygen gas -->  carbon dioxide gas + water

--------------------------------------...

[4] Looking only at the gases:

Photosynthesis: CO2 (gas) in and O2 (gas) out

Cellular respiration:O2 (gas) in -->.  CO2 (gas) out
