Final answer:
In photosynthesis, water and carbon dioxide are reactants, and GA3P and oxygen are products. Oxygen is released when water is split, and GA3P, a sugar, is formed in the Calvin Cycle.
Step-by-step explanation:
During the process of photosynthesis, plants convert light energy into chemical energy stored in glucose and other carbohydrates. Water and carbon dioxide are the reactants, while glucose and oxygen are the products of this process. Oxygen is produced when water molecules are split during the light-dependent reactions, which occurs before the Calvin Cycle where glucose is synthesized.
Based on the given options, the correct statement is (d): In photosynthesis, water and carbon dioxide are reactants. GA3P and oxygen are products. GA3P, or glyceraldehyde-3-phosphate, is a direct product of the Calvin Cycle that can be turned into glucose and other sugars. The energy for this process is provided by ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis.
