What is the overall outcome of the light reactions in photosynthesis?
A
Release of oxygen and carbon dioxide
B
Production of ATP and NADPH
C
Fixation of carbon dioxide into glucose
D
Conversion of glucose into pyruvate
Verified step by step guidance1
Understand that the light reactions of photosynthesis occur in the thylakoid membranes of chloroplasts and are the first stage of photosynthesis.
Recognize that the primary purpose of the light reactions is to convert solar energy into chemical energy in the form of ATP and NADPH.
Identify that during the light reactions, water molecules are split (photolysis), releasing oxygen as a byproduct.
Note that ATP and NADPH produced in the light reactions are then used in the Calvin cycle (dark reactions) to fix carbon dioxide into glucose.
Clarify that the light reactions do not directly involve the fixation of carbon dioxide or the conversion of glucose into pyruvate; these processes occur in subsequent stages of photosynthesis and cellular respiration, respectively.
