Which process in photosynthesis uses energy from the sun?(1 point)
Responses

splitting water into hydrogen and oxygen

absorbing carbon dioxide
absorbing carbon dioxide

releasing oxygen
releasing oxygen

combining carbon dioxide and hydrogen
combining carbon dioxide and hydrogen

Answer 1

The process in photosynthesis that uses energy from the sun is **combining carbon dioxide and hydrogen**. This process occurs during the Calvin cycle, where energy absorbed from sunlight during the light-dependent reactions is used to convert carbon dioxide and hydrogen (from water) into glucose.

Answer 2

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)
Responses

carbon dioxide
carbon dioxide

oxygen
oxygen

hydrogen gas
hydrogen gas

glucose

Answer 3

To help the bubbles reappear, the scientist should add **carbon dioxide** to the water. Carbon dioxide is one of the key reactants in the process of photosynthesis, and its availability is essential for the aquatic plant to produce oxygen and generate the bubbles observed on the leaves when photosynthesis occurs.

Answer 4

ATP is(1 point)
Responses

released when carbon dioxide and water form glucose
released when carbon dioxide and water form glucose

a form of energy that can be used and stored
a form of energy that can be used and stored

stored during cellular respiration
stored during cellular respiration

a form of energy that cannot be stored
a form of energy that cannot be stored

Answer 5

ATP is **a form of energy that can be used and stored**. ATP (adenosine triphosphate) serves as the main energy currency of cells, providing energy for various cellular processes and being rechargeable, meaning it can be regenerated from ADP and inorganic phosphate.

Answer 7

Here are the correct answers based on your previous questions:

1. **Which process in photosynthesis uses energy from the sun?**
- **Combining carbon dioxide and hydrogen**.

2. **Which substance should be added to the water in order for the bubbles to reappear?**
- **Carbon dioxide**.

3. **ATP is:**

Answer 8

ATP stores some of the energy from glucose molecules during cellular respiration. How is the remaining energy from these glucose molecules released?(1 point)
Responses

Excess water
Excess water

Excess carbon dioxide
Excess carbon dioxide

Excess heat
Excess heat

Excess light

Answer 9

The remaining energy from glucose molecules during cellular respiration is released as **excess heat**. While some energy is stored in the form of ATP, a significant portion of the energy is lost to the environment in the form of heat during the biochemical processes of cellular respiration.

Answer 10

Question
Which role does photosynthesis play in the flow of energy? (1 point)
Responses

Photosynthesis is how plants break down glucose to use for energy.
Photosynthesis is how plants break down glucose to use for energy.

Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.
Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.

Photosynthesis provides radiant energy to all the organisms in the entire food chain.
Photosynthesis provides radiant energy to all the organisms in the entire food chain.

Photosynthesis allows plants to create energy for themselves to store and use for metabolism.

Answer 11

The correct response is:

**Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.**

Photosynthesis captures solar energy and transforms it into chemical energy stored in glucose, which can then be utilized by plants and other organisms in the food chain.
