Solution
Sure, here are the answers to your questions:
Question 6: The correct answer is "The light dependent reaction". In this process, light energy is converted into chemical energy, and molecular oxygen is produced as a byproduct of the reaction.
Question 7: The correct answer is "by splitting two molecules of water". During photosynthesis, water molecules are split to release oxygen, hydrogen ions, and electrons.
Question 8: The correct answer is "both photosynthesis and respiration". ATP synthesis occurs during both processes. In photosynthesis, it happens in the light reactions, and in respiration, it happens in the mitochondria.
Question 9: The correct answer is "to function as the beginning of more complex molecules". Glucose is a simple sugar that plants produce during photosynthesis, and it serves as the starting point for the synthesis of many other types of molecules.
