Quiz On Photosynthesis And Cellular Respiration
The two most important features when we talk about plant life are photosynthesis and respiration. How well do you know about them? It's time to put your knowledge to test.
- 1.
What is one of the reactants 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 produce energy in the form of ATP. This process occurs in the mitochondria of cells and is essential for the survival and functioning of organisms. Glucose is obtained from the food we consume and serves as a fuel source for cellular respiration.Rate this question:

What are the products for photosynthesis?
- A.
Sugar + glucose
- B.
Carbon dioxide
- C.
Sugar + oxygen
- D.
Water + energy
Correct Answer
C. Sugar + oxygenExplanation
During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells and is essential for the plant's survival. The glucose produced is used as a source of energy for the plant, while the oxygen is released into the atmosphere as a byproduct. Therefore, the correct answer is "sugar + oxygen."Rate this question:

During respiration, the reactants of photosynthesis are changed into
- A.
H2O, CO2, and energy
- B.
C6H12O6 and O2
- C.
Energy and O2
- D.
C6H12O2 and H2O
Correct Answer
A. H2O, CO2, and energyExplanation
During respiration, the reactants of photosynthesis, which are glucose (C6H12O6) and oxygen (O2), are broken down to produce water (H2O), carbon dioxide (CO2), and energy. This process occurs in the mitochondria of cells and is necessary for the release of energy stored in glucose molecules.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+energy
- D.
6O2+C6H12O6+energy->6CO2+6H2O
Correct Answer
C. 6O2+c6H12O6->6CO2+6H2O+energyExplanation
The given equation represents the process of cellular respiration, where oxygen (O2) and glucose (C6H12O6) are used to produce carbon dioxide (CO2), water (H2O), and energy. This equation is balanced, meaning that the number of atoms of each element is the same on both sides of the equation. The inclusion of "energy" in the equation indicates that energy is released during cellular respiration. This equation is the correct representation of cellular respiration.Rate this question:

How much ATP does aerobic respiration produce?
- A.
2 ATP
- B.
15 ATP
- C.
20 ATP
- D.
36 ATP
Correct Answer
D. 36 ATPExplanation
Aerobic respiration is a process that occurs in the presence of oxygen and is the most efficient way for cells to produce energy. During aerobic respiration, glucose is broken down in a series of chemical reactions to produce ATP, which is the energy currency of cells. One molecule of glucose can produce a maximum of 36 ATP through aerobic respiration. This is because each molecule of glucose goes through glycolysis, the Krebs cycle, and the electron transport chain, which collectively generate a total of 36 ATP molecules.Rate this question:

Which is the correct equation for photosynthesis?
- A.
H2O + O2 -> energy+C6H12O6
- B.
CO2+H2O -> C6H12O6+O2
- C.
C6H12O6+energy -> H2O+O2
- D.
C6H12O6+O2 -> CO2+H2O
Correct Answer
B. CO2+H2O -> C6H12O6+O2Explanation
The correct equation for photosynthesis is CO2+H2O -> C6H12O6+O2. This equation represents the process of photosynthesis where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) using energy from sunlight.Rate this question:

What molecules does aerobic respiration use that anaerobic respiration is missing?
- A.
Oxygen
- B.
Glucose
- C.
Exercise
- D.
Light
Correct Answer(s)
A. Oxygen
C. ExerciseExplanation
Aerobic respiration requires oxygen as a molecule that anaerobic respiration lacks. Oxygen is essential for the final step of aerobic respiration, which is the electron transport chain, where the majority of ATP is produced. Anaerobic respiration, on the other hand, does not require oxygen and can use alternative molecules as terminal electron acceptors. Exercise is also mentioned as a molecule, but it is not a molecule that respiration uses. Light is not a molecule used in respiration at all.Rate this question:

- 8.
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 the mitochondria of cells. Both plant and animal cells have mitochondria, so cellular respiration can occur in both types of cells. Therefore, the correct answer is "both plants and animal cell."Rate this question:
