life processes Flashcards
What is respiration?
Respiration is the biochemical process by which living organisms convert glucose and oxygen into energy, carbon dioxide, and water.
True or False: Respiration occurs only in animals.
False
What are the two main types of respiration in organisms?
Aerobic and anaerobic respiration.
Fill in the blank: In aerobic respiration, glucose is completely broken down in the presence of __________.
oxygen
What is the main product of anaerobic respiration in plants?
Ethanol and carbon dioxide.
Which organ in humans is primarily responsible for gas exchange?
Lungs
True or False: Plants only perform photosynthesis and do not undergo respiration.
False
What is the chemical equation for aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
Short answer: Name one waste product of respiration.
Carbon dioxide
What process do plants use to convert sunlight into energy?
Photosynthesis
Multiple choice: Which of the following is a byproduct of anaerobic respiration in humans? A) Oxygen B) Lactic Acid C) Glucose
B) Lactic Acid
Fill in the blank: The energy currency of the cell produced during respiration is __________.
ATP
What is the role of mitochondria in cellular respiration?
Mitochondria are the sites where aerobic respiration occurs, producing ATP.
True or False: Respiration is the same as breathing.
False
What are stomata?
Stomata are small openings on the surfaces of leaves that allow gas exchange.
Short answer: What is the main function of respiration in living organisms?
To produce energy.
Multiple choice: Which type of respiration occurs in the absence of oxygen? A) Aerobic B) Anaerobic C) Both
B) Anaerobic
Fill in the blank: The process by which glucose is partially broken down in the absence of oxygen is called __________.
fermentation
What is the significance of respiration in plants?
Respiration provides energy for growth, development, and cellular processes.
True or False: Respiration rates can vary between different organisms.
True
What do plants release as a byproduct of photosynthesis?
Oxygen
What is the main respiratory pigment in humans?
Hemoglobin
Fill in the blank: During cellular respiration, glucose is oxidized to produce __________.
energy (ATP)
Short answer: How do plants obtain the carbon dioxide necessary for respiration?
Through stomata from the atmosphere.
