Glucose is a carbohydrate formed by using energy to convert carbon dioxide and water bonded glucose molecules. What type of reaction does this represent?
a. cellular respiration
b. ATP
c. dehydration synthesis
d. photosynthesis
d. photosynthesis
The given process of using energy to convert carbon dioxide and water into glucose molecules represents photosynthesis. Thus, the correct answer is d. photosynthesis.
The process you are referring to is known as photosynthesis, where plants use energy from sunlight to convert carbon dioxide and water into glucose and release oxygen as a byproduct. Therefore, the correct answer is d. photosynthesis.
To arrive at this answer, we can break down the options and look for clues:
a. Cellular respiration: This is the process by which cells break down glucose into energy, usually in the presence of oxygen. It is the opposite reaction of photosynthesis and does not involve the formation of glucose.
b. ATP: Adenosine triphosphate (ATP) is a molecule involved in energy transfer within cells. While ATP is produced through cellular respiration, it is not directly related to the formation of glucose.
c. Dehydration synthesis: This is a reaction in which two molecules are joined together, producing a larger molecule and releasing a water molecule. While dehydration synthesis is involved in building complex carbohydrates from smaller sugar molecules, it does not explain the specific process mentioned in the question.
d. Photosynthesis: As detailed earlier, photosynthesis is the process by which plants convert carbon dioxide and water into glucose using energy from sunlight. This process results in the release of oxygen, making it the correct answer in this case.
Therefore, the correct answer is d. photosynthesis.
