The process in photosynthesis that uses energy from the sun is **combining carbon dioxide and hydrogen**. This occurs during the Calvin cycle, where the energy captured from sunlight is used to convert carbon dioxide and hydrogen (from water) into glucose.
However, it is important to clarify that the light-dependent reactions (not explicitly mentioned in your options) primarily utilize sunlight to split water and release oxygen.
If you are looking for the best answer based on the options provided, then **combining carbon dioxide and hydrogen** would be the most closely related to the use of sunlight energy during the overall photosynthesis process.

A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant’s leaves on days 1 and 2, but no bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be added to the water in order for the bubbles to reappear?(1 point)

In order for the bubbles to reappear, the scientist should add **carbon dioxide** to the water.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The bubbles observed on the plant’s leaves were likely oxygen being released as a byproduct of photosynthesis. Without sufficient carbon dioxide, the plant would not be able to perform photosynthesis effectively, which could explain why no bubbles were observed on day 3. Adding carbon dioxide would enable the plant to resume photosynthesis and produce oxygen again, leading to the formation of bubbles.

ATP is **a form of energy that cannot be stored**.
ATP (adenosine triphosphate) is the primary energy carrier in living organisms, and it is used to store and transfer energy within cells. However, ATP itself is typically used immediately for energy in cellular processes and is not stored in significant amounts within cells. Instead, cells continuously regenerate ATP from ADP (adenosine diphosphate) and inorganic phosphate through processes like cellular respiration and photosynthesis.

The remaining energy from glucose molecules during cellular respiration is released as **excess heat**.
When glucose is broken down to produce ATP, not all the energy from glucose is converted into ATP. Some of it is lost as heat during the process, which helps maintain body temperature in warm-blooded organisms and is a byproduct of the metabolic reactions involved in cellular respiration.

One molecule of glucose is recycled into **6** molecules of carbon dioxide during cellular respiration.
The process of cellular respiration, specifically during the Krebs cycle (or citric acid cycle), completely oxidizes one molecule of glucose, producing 6 molecules of carbon dioxide as a byproduct.
