What is one of the reactants (substrates) for cellular respiration?
- A.
Glucose
- B.
Water
- C.
Carbon dioxide
- D.
Energy
Correct Answer
A. GlucoseExplanation
Glucose is one of the reactants for cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to release energy in the form of ATP. Glucose is a carbohydrate molecule that serves as a primary source of energy for cells. It is obtained from the breakdown of carbohydrates in the diet and is transported to cells through the bloodstream. Once inside the cells, glucose undergoes a series of chemical reactions in the mitochondria to produce ATP, which is used for various cellular processes.Rate this question:

What are the products of photosynthesis?
- A.
Sugar + glucose
- B.
Carbon dioxide
- C.
Sugar + oxygen
- D.
Water + energy
Correct Answer
C. Sugar + oxygenExplanation
Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen. Glucose is an essential energy source for plants, while oxygen is released as a byproduct. Therefore, the correct answer is "sugar + oxygen."Rate this question:

In cellular respiration, what is the correct equation:
- A.
602+C6H12O6+energy -> 6CO2+6H2O
- B.
6CO2+6H2O+energy->6O2+c6H12O6
- C.
6O2+c6H12O6->6CO2+6H2O+ATP
- D.
6O2 + C6H12O6 + energy -> 6CO2 + 6H2O + ATP
Correct Answer
D. 6O2 + C6H12O6 + energy -> 6CO2 + 6H2O + ATPExplanation
The correct equation for cellular respiration is:
6O2 + C6H12O6 + energy -> 6CO2 + 6H2O + ATP
This equation shows that oxygen (O₂) and glucose (C₆H₁₂O₆) react to produce carbon dioxide (CO₂), water (H₂O), and ATP (energy).Rate this question:

How much ATP does aerobic respiration produce?
- A.
2 ATP
- B.
15 ATP
- C.
20 ATP
- D.
38 ATP
Correct Answer
D. 38 ATPExplanation
Aerobic respiration is the process by which cells convert glucose into energy in the presence of oxygen. During this process, a total of 38 ATP molecules are produced. ATP is the primary energy currency of cells, and it is used for various cellular processes. Therefore, the correct answer is 38 ATP.Rate this question:

Which is the correct equation for photosynthesis?
- A.
6H2O + 6CO2 -> ATP+C6H12O6 + 6O2
- B.
6CO2+6H2O -> C6H12O6+6O2
- C.
C6H12O6+ATP -> 6H2O+C6
- D.
C6H12O6+6O2 -> 6CO2+6H2O
Correct Answer
B. 6CO2+6H2O -> C6H12O6+6O2Explanation
The correct equation for photosynthesis is 6CO2+6H2O -> C6H12O6+6O2. This equation represents the process of photosynthesis in which carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) with the help of sunlight energy. This equation accurately reflects the inputs and outputs of photosynthesis.Rate this question:

What molecule does aerobic respiration use that anaerobic respiration is missing?
- A.
Oxygen
- B.
Glucose
- C.
Exercise
- D.
Light
Correct Answer
A. OxygenExplanation
Aerobic respiration is a process that occurs in the presence of oxygen and is more efficient in generating energy compared to anaerobic respiration. Oxygen is the molecule used in aerobic respiration as the final electron acceptor in the electron transport chain, allowing for the complete breakdown of glucose and the production of ATP. Anaerobic respiration, on the other hand, does not use oxygen as the final electron acceptor, resulting in the incomplete breakdown of glucose and the production of less ATP.Rate this question:

Cellular respiration occurs in which cell type?
- A.
Plant cells only
- B.
Animal cell only
- C.
Both plants and animal cell
- D.
All but plant cells
Correct Answer
C. Both plants and animal cellExplanation
Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in both plant and animal cells. In plants, cellular respiration takes place in the mitochondria of cells, while in animals, it occurs in the mitochondria of most cells. Both plant and animal cells require energy for their metabolic processes, so they both undergo cellular respiration to produce ATP, the energy currency of cells. Therefore, the correct answer is both plants and animal cells.Rate this question:

What molecules belong in the box of the diagram?
- A.
1 transpiration; 2 respiration
- B.
1 chemosynthesis; 2 photosynthesis
- C.
1 respiration; 2 photosynthesis
- D.
1 photosynthesis; 2 respiration
Correct Answer
D. 1 photosynthesis; 2 respirationExplanation
The correct answer is 1 photosynthesis; 2 respiration. This is because photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Respiration, on the other hand, is the process by which organisms break down glucose to release energy. Both processes are essential for the survival of living organisms.Rate this question:

In cellular respiration, energy can be released by breaking down which molecule?
- A.
ATP
- B.
Carbon dioxide
- C.
Glucose
- D.
Water
Correct Answer
C. GlucoseExplanation
Glucose is the correct answer because it is the molecule that is broken down during cellular respiration to release energy. This process occurs in the mitochondria of cells and involves a series of chemical reactions that convert glucose into ATP (adenosine triphosphate), which is the main source of energy for cellular activities. Glucose is a carbohydrate that is obtained from the food we eat and is stored in the body for later use. When energy is needed, glucose is broken down through a series of metabolic reactions, ultimately producing ATP and releasing energy.Rate this question:
