Which organelle is primarily responsible for photosynthesis in plant cells?
Mitochondria
Chloroplast
Nucleus
Ribosome
What is the main function of mitochondria in eukaryotic cells?
Protein synthesis
Energy production
Photosynthesis
Storage of genetic material
Which molecule is produced during the light-dependent reactions of photosynthesis?
Glucose
ATP
Pyruvate
Lactic acid
What is the first stage of cellular respiration called?
Krebs cycle
Glycolysis
Electron transport chain
Calvin cycle
Which gas is released as a byproduct during photosynthesis?
Carbon dioxide
Oxygen
Nitrogen
Methane
Which part of the chloroplast contains chlorophyll and is the site of the light-dependent reactions?
Stroma
Thylakoid membrane
Outer membrane
Matrix
During cellular respiration, which stage produces the most ATP?
Glycolysis
Krebs cycle
Electron transport chain
Fermentation
How does ATP synthase produce ATP during cellular respiration?
By breaking down glucose
By using a proton gradient across the mitochondrial membrane
By absorbing sunlight
By combining oxygen and carbon dioxide
Which process converts solar energy into chemical energy in plants?
Cellular respiration
Photosynthesis
Fermentation
Digestion
What is the role of NADH in cellular respiration?
It acts as a structural protein
It transports electrons to the electron transport chain
It stores genetic information
It absorbs light energy
Compare the roles of chloroplasts and mitochondria in energy transformation within a cell.
Both produce glucose
Chloroplasts convert light energy to chemical energy; mitochondria convert chemical energy to usable cellular energy (ATP)
Both perform photosynthesis
Both store genetic material
Explain why the light-dependent reactions must occur before the Calvin cycle in photosynthesis.
The Calvin cycle produces ATP needed for light-dependent reactions
Light-dependent reactions generate ATP and NADPH required for the Calvin cycle
The Calvin cycle absorbs sunlight
Light-dependent reactions produce glucose
A student observes that a plant placed in the dark for several days stops producing oxygen. Using your knowledge of photosynthesis, explain why this occurs.
Oxygen is only produced during cellular respiration
Light-dependent reactions require light to split water and release oxygen
Plants use carbon dioxide in the dark to produce oxygen
Oxygen is produced during fermentation
Design an experiment to test the effect of light intensity on the rate of photosynthesis in aquatic plants. Which variable would you measure to determine the rate?
Amount of glucose produced
Number of leaves
Volume of oxygen bubbles released
Color of the plant
A cell is unable to produce enough ATP through aerobic respiration due to a lack of oxygen. What alternative process might the cell use, and what is a possible consequence?
Photosynthesis; increased oxygen production
Fermentation; less ATP produced and possible buildup of lactic acid
Calvin cycle; more glucose produced
Electron transport chain; more ATP produced
Use this diagram to select the best statement which describes the process of photosynthesis.
photosynthesis happens in the mitochondria
photosynthesis produces CO2 and H2O
photosynthesis produces glucose and O2
photosynthesis does not require sunlight
What is being released at "A" in the diagram?
