What does photosynthesis use to convert water and carbon dioxide into oxygen and high energy sugars?
- A.
ATP energy
- B.
NADPH energy
- C.
Sunlight energy
- D.
NADP energy
Correct Answer
C. Sunlight energyExplanation
Photosynthesis is the process by which plants convert water and carbon dioxide into oxygen and high energy sugars. This process requires energy, which is provided by sunlight. Sunlight energy is captured by the pigment chlorophyll in plant cells and is used to power the conversion of water and carbon dioxide into oxygen and sugars. ATP and NADPH are molecules that are produced during the light-dependent reactions of photosynthesis and are used as energy sources in the subsequent light-independent reactions. However, the initial source of energy for photosynthesis is sunlight.Rate this question:

During the process of photosynthesis, what happens?
- A.
Chemical energy is converted to light energy
- B.
Produce GTP
- C.
Light energy is converted to chemical energy
- D.
Essential to oxygen production
Correct Answer
C. Light energy is converted to chemical energyExplanation
During the process of photosynthesis, light energy is converted to chemical energy. This is achieved through a series of chemical reactions in which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose and oxygen. The light energy is absorbed by pigments such as chlorophyll, which then initiates a chain of reactions that convert the light energy into chemical energy stored in the bonds of glucose molecules. This chemical energy is essential for the survival and growth of plants and other organisms that rely on photosynthesis for their energy needs.Rate this question:

In which organelle does photosynthesis take place?
- A.
Chlorophyll
- B.
Thylakoid
- C.
Chloroplast
- D.
Impalas
Correct Answer
C. ChloroplastExplanation
Photosynthesis is the process by which plants convert sunlight into energy. It occurs in the chloroplasts, which contain chlorophyll, the pigment responsible for capturing light energy. The chloroplasts contain specialized structures called thylakoids, where the light-dependent reactions of photosynthesis take place. These reactions involve the absorption of light energy by chlorophyll and the conversion of that energy into chemical energy in the form of ATP and NADPH. Therefore, the correct answer is chloroplast, as it is the organelle where photosynthesis occurs.Rate this question:

What is the one product of photosynthesis?
- A.
Oxygen
- B.
Glucose
- C.
Hydogen
- D.
Carbon dioxide
Correct Answer
D. Carbon dioxideExplanation
The one product of photosynthesis is glucose, not carbon dioxide. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Glucose is a type of sugar that plants use for energy, while oxygen is released into the atmosphere as a byproduct. Carbon dioxide is actually one of the reactants in photosynthesis, not a product.Rate this question:

What is the difference between aerobic respiration and anaerobic respiration?
- A.
Aerobic is the process that requires oxygen and anaerobic respiration doesn’t.
- B.
Anaerobic is the process that requires oxygen and areobic respiration doesn't.
- C.
Aerobic is the process that requires glucose and anaerobic respiration doesn't.
- D.
Anaerobic is the process that requires glucose and anaerobic respiration doesn't.
Correct Answer
A. Aerobic is the process that requires oxygen and anaerobic respiration doesn’t.Explanation
Aerobic respiration is a process that occurs in the presence of oxygen, while anaerobic respiration occurs in the absence of oxygen. Oxygen is necessary for aerobic respiration to take place, as it is the final electron acceptor in the electron transport chain. In contrast, anaerobic respiration utilizes other electron acceptors, such as sulfate or nitrate. This difference in electron acceptors leads to different end products being produced during the two types of respiration.Rate this question:

Why is light and chlorophyll needed for photosynthesis?
- A.
To lower the energy level
- B.
To raises the energy level
- C.
To equal the energy level
- D.
To store energy
Correct Answer
B. To raises the energy levelExplanation
Light and chlorophyll are needed for photosynthesis to raise the energy level. During photosynthesis, chlorophyll absorbs light energy from the sun. This energy is then used to convert carbon dioxide and water into glucose and oxygen. The light energy is crucial for the process as it provides the necessary energy to drive the chemical reactions involved in photosynthesis. Chlorophyll acts as a pigment that captures the light energy and transfers it to the reaction centers in the chloroplasts, where it is used to raise the energy level of the electrons involved in the synthesis of glucose.Rate this question:

What happens in a light-dependent reaction?
- A.
It produces oxygen, gas, and convert ATP and NADPH into the energy carriers ADP and NADP.
- B.
It produces carbon dioxide, glucose, and convert ATP and NADPH into the energy carriers ADP and NADP.
- C.
It produces oxygen, gas, and convert ADP and NADP into the energy carriers ATP and NADPH.
- D.
It produces carbon dioxide, glucose, and convert ADP and NADP into the energy carriers ATP and NADPH.
Correct Answer
C. It produces oxygen, gas, and convert ADP and NADP into the energy carriers ATP and NADPH.Explanation
In a light-dependent reaction, oxygen gas is produced as a byproduct, and ADP and NADP are converted into the energy carriers ATP and NADPH. This process occurs in the thylakoid membrane of chloroplasts during photosynthesis. The energy from sunlight is absorbed by chlorophyll and other pigments, which then excite electrons. These excited electrons are passed through a series of electron carriers, generating ATP through chemiosmosis and reducing NADP to NADPH. Oxygen gas is released as a result of splitting water molecules.Rate this question:

The light-independent reaction of photosynthesis is also known as the?
- A.
Priestly cycle
- B.
Van Helmont cycle
- C.
Calvin Cycle
- D.
Igenhousz cycle
Correct Answer
C. Calvin CycleExplanation
The light-independent reaction of photosynthesis is also known as the Calvin Cycle. This cycle takes place in the stroma of the chloroplasts and converts carbon dioxide into glucose. It is named after Melvin Calvin, who discovered and described the cycle in the 1950s. The Calvin Cycle is essential for the production of carbohydrates, which are then used as a source of energy for the plant. It is a complex series of chemical reactions that require enzymes and ATP (adenosine triphosphate) to function properly.Rate this question:

Aerobic respiration produce substantially more ATP than anaerobic respiration.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Aerobic respiration produces more ATP than anaerobic respiration because it involves the complete breakdown of glucose in the presence of oxygen, resulting in the production of 36-38 ATP molecules. On the other hand, anaerobic respiration only partially breaks down glucose in the absence of oxygen, producing only 2 ATP molecules. Therefore, aerobic respiration is more efficient in generating ATP compared to anaerobic respiration.Rate this question:

What happens during the Calvin Cycle?
- A.
It uses ATP and NADPH from the light-dependent reactions to produce low-energy sugars.
- B.
It uses ATP and NADPH from the light-independent reactions to produce low-energy sugars.
- C.
It uses ATP and NADPH from the light-dependent reactions to produce high-energy sugars.
- D.
It uses ATP and NADPH from the light-independent reactions to produce high-energy sugars.
Correct Answer
C. It uses ATP and NADPH from the light-dependent reactions to produce high-energy sugars.Explanation
During the Calvin Cycle, ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide into high-energy sugars through a series of chemical reactions. This process occurs in the stroma of the chloroplasts and is also known as the dark reaction or the light-independent reaction of photosynthesis. The high-energy sugars produced during the Calvin Cycle are essential for the growth and development of plants.Rate this question:
