Final answer:
G3P is used in the production of glucose and sucrose, with both being carbohydrate molecules that plants synthesize through the Calvin cycle during photosynthesis (Options B and D).
Step-by-step explanation:
G3P, or glyceraldehyde-3-phosphate, is a molecule that plays a crucial role in various biochemical processes within plants, including the synthesis of carbohydrate molecules.
G3P is used in the production of glucose, which is a simple sugar and the main energy source for cells.
Moreover, it is also involved in the production of sucrose, which is a disaccharide composed of glucose and fructose.
During photosynthesis, G3P is generated in the Calvin cycle and can be used to form a variety of carbohydrates.
The Calvin cycle harnesses energy in the form of ATP and NADPH to produce GA3P molecules, which can then be converted into glucose, sucrose, starch, cellulose, and other polysaccharides.
The cycle is a defining example of a biochemical pathway where the end product is also a reactant, known as a cycle because it regenerates the initial molecule, RuBP, using the energy stored in ATP and NADPH.
Hence, the correct answers are Options B and D.
