Question
Chapter 10, Problem 10.2CR
Summary Introduction
To find: Role of CO2 and H2O in
Introduction: Photosynthesis is the process of converting CO2 and water into simple sugar in the presence of sunlight. Cellular respiration is the process of breaking down simple sugar, obtained from photosynthesis, into CO2 and water and releasing energy in the form of ATP.
