Exercise 1 Photosynthesis can be described by the following equation: 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O Explain the equation in words and indicate which of the molecules are gases. Exercise 2 Explain briefly the two main parts of photosynthesis. Exercise 3 Explain and describe how ATP and NADPH are created during the light reaction. Exercise 4 Explain in detail the part of photosynthesis where CO2 is incorporated into a new molecule. Exercise 5 Where in the photosynthesis process do redox reactions occur? Exercise 6 What is the purpose of pigments, and why do plants have several of them? Algae are not plants, but they perform photosynthesis. Why are red algae found relatively deep in the sea?
