Reactants of Photosynthesis & Respiration (as well as the product)

Click For Summary
SUMMARY

The reactants of photosynthesis are 6H2O and 6CO2, which, in the presence of light energy, produce C6H12O6 (glucose) and 6O2 (oxygen). The reactants for aerobic respiration are glucose and oxygen, yielding 6H2O and 6CO2, along with 38 ATP molecules as energy. It is essential to include ATP in the respiration equation to accurately represent the energy produced. Understanding these equations is crucial for grasping the processes of photosynthesis and respiration in biological systems.

PREREQUISITES
  • Basic knowledge of chemical equations
  • Understanding of photosynthesis and respiration processes
  • Familiarity with ATP and its role in cellular energy
  • Concept of light energy absorption in photosynthesis
NEXT STEPS
  • Study the detailed mechanisms of photosynthesis, including light-dependent and light-independent reactions.
  • Explore the Krebs cycle and its role in aerobic respiration.
  • Learn about Gibbs Free Energy and its implications in biochemical reactions.
  • Investigate the efficiency of energy conversion in cellular respiration.
USEFUL FOR

Students studying biology, educators teaching photosynthesis and respiration, and anyone interested in understanding energy transformations in living organisms.

I just want to know if the info that I am retaining is right.

The reactants of photosynthesis is

6H20 + 6CO2

which would be six molecules of water and six molecules of carbon dioxide.

The product - would be C6H12O6 + 6O2 which would be one molecule of sugar plus six molecules of O2.

The reactants for respiration are glucose and oxygen.

The product would be 6H2O + 6CO2.


If this is correct please let me know, so I know I am on the right track..
Thanks RG

Don't forget to put light in the photosynthesis equation :) Also, be sure to denote the second equation as "aerobic respiration" and it yields ATP (energy). You're on the right track.

Ohhhhhhhhhhh

so it would be 6Co2 + 6H20 + light energy ..right?



The free energy would that be the ATP?

Glucose + oxygen --------> carbon dioxide + water (free energy)
(aerobic respiration)
 
Yes, the photosynthesis equation is looking good.

I wouldn't use the term "free energy" with ATP as it can be confusing when you start to learn about Gibbs Free Energy. Just call it an "energy source". The equation you provided also needs ATP on the reactants side.

Where would I put the ATP ?
 
Photosynthesis
6H20 + 6CO2 + light energy(absorbed by chlorophyll --> C6H12O6 + 6O2

So
6*water + 6*Carbon dioxide + light --> 1*glucose + 6*oxygen

Respiration
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energi ( 38 ATP-molekyler= 40%)( + 60% Heat).

So
1*Glucose + 6*oxygen --> 6 carbon dioxide + 6*water + energi(38 ATP-molekyler= 40%)( + 60% Heat)
 
I hope RainGurl's teacher is accomodating and will allow her to turn in her work a bit late... 4 1/2 years late!
 
Nice!
