Bio Flashcards
What is the primary function of photosynthesis?
To convert light energy into chemical energy in the form of glucose.
True or False: Photosynthesis occurs in the mitochondria of plant cells.
False
Fill in the blank: The two main stages of photosynthesis are the _____ and the Calvin cycle.
light reactions
What molecule is produced as a byproduct of photosynthesis?
Oxygen
What is the main pigment involved in photosynthesis?
Chlorophyll
Which gas is consumed during photosynthesis?
Carbon dioxide
What are the three phases of the Calvin cycle?
Carbon fixation, reduction, and regeneration of RuBP.
True or False: The Calvin cycle requires light to occur.
False
What is the primary energy source for the light reactions of photosynthesis?
Sunlight
In which part of the plant cell does photosynthesis occur?
Chloroplasts
Multiple Choice: Which of the following is NOT a product of the light reactions? A) ATP B) NADPH C) Glucose D) Oxygen
C) Glucose
What is the role of ATP in the Calvin cycle?
ATP provides the energy needed for the conversion of 3-PGA to G3P.
Fill in the blank: Cellular respiration is the process by which cells convert _____ into usable energy.
glucose
What are the three main stages of cellular respiration?
Glycolysis, the Krebs cycle, and the electron transport chain.
True or False: Cellular respiration occurs in both plant and animal cells.
True
What is the net gain of ATP from glycolysis?
2 ATP
In which part of the cell does the Krebs cycle take place?
Mitochondrial matrix
What is the purpose of the electron transport chain in cellular respiration?
To create a proton gradient that drives ATP synthesis.
Multiple Choice: Which molecule is the final electron acceptor in the electron transport chain? A) Carbon Dioxide B) Oxygen C) Glucose D) NADH
B) Oxygen
Fill in the blank: The process of converting glucose into pyruvate is called _____
glycolysis
What is produced during the Krebs cycle?
NADH, FADH2, ATP, and carbon dioxide.
True or False: Fermentation occurs in the absence of oxygen.
True
What type of fermentation occurs in muscle cells during strenuous exercise?
Lactic acid fermentation
What is the overall equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
What is the overall equation for cellular respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
