Photosynthesis And Cellular Respiration 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
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 is the chemical equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Which organelle is responsible for cellular respiration?
Mitochondria
True or False: Cellular respiration occurs only in plants.
False
What are the three main stages of cellular respiration?
Glycolysis, Krebs cycle, and electron transport chain.
Multiple choice: Which molecule is the primary energy carrier in cells?
ATP
What is the main purpose of the Krebs cycle?
To produce electron carriers (NADH and FADH2) for the electron transport chain.
Fill in the blank: The end products of glycolysis are ______ and ______.
pyruvate and ATP
True or False: Oxygen is a byproduct of cellular respiration.
False
What is the role of NADH in cellular respiration?
It acts as an electron carrier to transport electrons to the electron transport chain.
Multiple choice: Which process occurs in the cytoplasm?
Glycolysis
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP.
Fill in the blank: The final electron acceptor in the electron transport chain is ______.
oxygen
What is produced during the light-dependent reactions of photosynthesis?
ATP and NADPH
True or False: The Calvin cycle requires light directly to occur.
False
What are the inputs of the Calvin cycle?
CO2, ATP, and NADPH
Multiple choice: Which process can occur without oxygen?
Anaerobic respiration
What is lactic acid fermentation?
A type of anaerobic respiration that occurs in muscle cells, producing lactic acid.
Fill in the blank: The primary product of alcoholic fermentation is ______.
ethanol
True or False: Both plants and animals perform cellular respiration.
True
What is the main purpose of photosynthesis for plants?
To produce food (glucose) and oxygen.
