Cellular Respiration Photosynthesis
Occurs in all living organisms .
Occurs only in all green plants , algae , and in some bacteria .
The ENTIRE process occurs in Mitochondria .
The entire process occurs in Chloroplasts.
Glucose and OXYGEN are the reactants of this process .
Carbon dioxide, water, and light energy are the reactants of this process.
Carbon dioxide, water , and energy ( ATP ) are the by -products .
Glucose, oxygen , and water are the by -products.
Undergoes Catabolic Process.
Undergoes Anabolic Process.
Oxygen is taken in and carbon dioxide is liberated out .
Producing food and capturing energy .
In this process, food particles are broken down to release energy .
In this process, food is synthesis by capturing the energy .
It is an exergonic reaction as energy is RELEASED .
It is an endothermic reaction as it requires energy .
This process does not require sunlight since cellular respiration occurs all the time .
This process requires sunlight since photosynthesis occurs only in the PRESENCE of sunlight .
The chemical reaction of cellular Respiration is
C 6H12 O6 + 6 O2 → 6 CO2 + 6H 2O
The chemical reaction of photosynthesis is
6CO 2 + 6H2 O → C 6 H12O 6+ 6O2
