What is the primary purpose of photosynthesis?
To convert light energy into chemical energy in the form of glucose.
True or False: Photosynthesis occurs only in plants.
False
What are the two main stages of photosynthesis?
Light-dependent reactions and the Calvin cycle.
Fill in the blank: The pigment primarily responsible for capturing light energy in plants is called __________.
chlorophyll
What are the raw materials required for photosynthesis?
Carbon dioxide, water, and sunlight.
Which organelle is known as the site of photosynthesis in plant cells?
Chloroplast
What is the formula for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
True or False: Respiration is the process by which cells convert glucose into usable energy.
True
What is the main byproduct of cellular respiration?
Carbon dioxide
What are the three main stages of cellular respiration?
Glycolysis, Krebs cycle, and electron transport chain.
Fill in the blank: The process of breaking down glucose without oxygen is called __________.
anaerobic respiration
What is the energy currency of the cell produced during respiration?
ATP (adenosine triphosphate)
Where does glycolysis occur in the cell?
In the cytoplasm.
What is the primary difference between aerobic and anaerobic respiration?
Aerobic respiration requires oxygen, while anaerobic respiration does not.
True or False: The Calvin cycle occurs in the mitochondria.
False
What is produced during the Krebs cycle?
NADH, FADH2, ATP, and carbon dioxide.
Fill in the blank: The electron transport chain occurs in the __________ of the mitochondria.
inner membrane
What are the two main types of fermentation?
Lactic acid fermentation and alcoholic fermentation.
What is the role of oxygen in aerobic respiration?
Oxygen acts as the final electron acceptor in the electron transport chain.
True or False: All living organisms perform some form of respiration.
True
What is the main function of chlorophyll in photosynthesis?
To absorb light energy.
What byproduct is released during photosynthesis?
Oxygen
What is the term for the process of converting light energy into chemical energy?
Photosynthesis
