Photosynthesis And Cellular Respiration Quiz Questions
Many of us will remember learning about photosynthesis in high school – it may be the only thing you can recall from biology class! But if you’re studying it, try your hand at this quiz and see how much you remember!
- 1.
The site of Photosynethsis takes place in the
- A.
Choroplasts
- B.
Stroma
- C.
Thylakoid membrane
- D.
Grana
Correct Answer
A. ChoroplastsExplanation
Photosynthesis is a process that occurs in the chloroplasts of plant cells. Chloroplasts are organelles found in the cells of green plants and algae, and they contain chlorophyll, which is responsible for capturing sunlight and converting it into chemical energy through photosynthesis. The chloroplasts contain various structures, including the stroma, thylakoid membrane, and grana, which are all involved in different stages of the photosynthetic process. However, the overall site of photosynthesis is the chloroplasts, where the necessary components and enzymes are present for the process to occur.Rate this question:

Light dependent reactions have the following reactants
- A.
Light, water, ADP, NADH
- B.
Light ATP, NADPH, glucose
- C.
Light, oxygen, ADP, phosphate
- D.
Light, oxygen, glucose, co2
Correct Answer
A. Light, water, ADP, NADHExplanation
The correct answer is light, water, ADP, NADH. In light dependent reactions of photosynthesis, light energy is absorbed by chlorophyll and converted into chemical energy. Water is split, releasing oxygen and providing electrons for the electron transport chain. ADP is converted into ATP, and NADH is produced as a carrier molecule for energized electrons. This answer accurately lists all the necessary reactants for light dependent reactions.Rate this question:

Light independent reactions have the following reactants
- A.
oxygen, ADP, phosphate
- B.
Glucose, ATP, oxygen
- C.
glucose, CO2, NADP
- D.
ATP, NADPH, CO2
Correct Answer
D. ATP, NADPH, CO2Explanation
The correct answer is ATP, NADPH, CO2. In light-independent reactions, also known as the Calvin cycle, ATP and NADPH produced during the light-dependent reactions are used to convert carbon dioxide (CO2) into glucose. Oxygen is not a reactant in the Calvin cycle, but rather a byproduct of the light-dependent reactions. ADP and phosphate are involved in the regeneration of ATP during the cycle, but they are not reactants. Glucose, ATP, and oxygen are not reactants in the light-independent reactions.Rate this question:

Uses of ATP in cellular respiration
- A.
Active transport
- B.
Muscle contraction
- C.
Cytoplasmic streaming
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
ATP, or adenosine triphosphate, is the main energy currency in cells. It is used in various cellular processes, including active transport, muscle contraction, and cytoplasmic streaming. Active transport refers to the movement of molecules across a cell membrane against their concentration gradient, and this process requires energy provided by ATP. Muscle contraction is powered by ATP, which is needed for the interaction between actin and myosin filaments. Cytoplasmic streaming is the movement of cytoplasm within cells, and ATP is involved in this process as well. Therefore, all of the given options are correct uses of ATP in cellular respiration.Rate this question:

Anaerobic respiration has
- A.
No oxygen available
- B.
Takes place in the cytoplasm
- C.
Has oxygen available
- D.
Both a and b
- E.
Both c and b
Correct Answer
D. Both a and bExplanation
Anaerobic respiration is a type of cellular respiration that occurs in the absence of oxygen. It takes place in the cytoplasm of cells, where glucose is broken down to produce energy in the form of ATP. Therefore, the correct answer is "both a and b" because anaerobic respiration does not require oxygen and occurs in the cytoplasm.Rate this question:

Chose the step on aerobic respiration in order
- A.
Glycolysis, citric acid cycle, linking reaction, oxidative phosporylation
- B.
Citric acid cycle, glycolysis, linking reaction, oxidative phosporylation
- C.
Glycolysis, linking reaction, krebs cycle, oxidative phosporylation
- D.
Glycolysis, oxidative phosporylation, linking reaction, citric acid cycle,
Correct Answer
C. Glycolysis, linking reaction, krebs cycle, oxidative phosporylationExplanation
The correct order of steps in aerobic respiration is glycolysis, linking reaction, Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation. Glycolysis is the initial step where glucose is converted into pyruvate. The linking reaction then converts pyruvate into acetyl CoA, which enters the Krebs cycle. In the Krebs cycle, acetyl CoA is further broken down, producing energy-rich molecules. Finally, oxidative phosphorylation occurs, where the energy stored in the energy-rich molecules is used to generate ATP.Rate this question:

Light dependent reactions take place in the
- A.
Stroma
- B.
Thylakoid membrane
- C.
Grana
- D.
Cloraplasts
Correct Answer
B. Thylakoid membraneExplanation
The correct answer is the thylakoid membrane. Light-dependent reactions are the first stage of photosynthesis, where light energy is converted into chemical energy in the form of ATP and NADPH. These reactions occur in the thylakoid membrane of the chloroplasts. The thylakoid membrane contains chlorophyll and other pigments that absorb light energy. This energy is then used to generate ATP and NADPH, which are essential for the next stage of photosynthesis, the Calvin cycle.Rate this question:

Light independent reactions take place in the
- A.
Grana
- B.
Stroma
- C.
Thylakoid membrane
- D.
Cloraplasts
Correct Answer
B. StromaExplanation
The light-independent reactions, also known as the Calvin cycle, occur in the stroma of the chloroplasts. During this process, carbon dioxide is converted into glucose using the energy generated from the light-dependent reactions. The stroma is the fluid-filled region of the chloroplast where the enzymes and other molecules necessary for the Calvin cycle are present. Therefore, the stroma is the correct answer for the location of light-independent reactions.Rate this question:

Packets of light energy are called
- A.
ATP
- B.
Light energy
- C.
Photons
- D.
Protons
Correct Answer
C. PhotonsExplanation
Photons are packets of light energy. They are the fundamental particles that make up light and electromagnetic radiation. They have no mass and travel at the speed of light. Photons carry energy and can interact with matter, causing various phenomena such as absorption, reflection, and emission of light. Therefore, photons are the correct answer for packets of light energy.Rate this question:
