B4 aerobic and anaerobic respiration Flashcards
What is the primary purpose of respiration in living organisms?
To release energy from glucose.
What are the two main types of respiration?
Aerobic respiration and anaerobic respiration.
True or False: Aerobic respiration requires oxygen.
True.
What is the chemical equation for aerobic respiration?
Glucose + Oxygen → Carbon Dioxide + Water + Energy.
Fill in the blank: Anaerobic respiration occurs in the absence of ______.
Oxygen.
What type of respiration do yeast cells perform?
Anaerobic respiration (fermentation).
What is produced during anaerobic respiration in muscles?
Lactic acid.
Multiple Choice: Which process generates more energy per glucose molecule? A) Aerobic respiration B) Anaerobic respiration
A) Aerobic respiration.
What is the main product of anaerobic respiration in yeast?
Ethanol (alcohol) and carbon dioxide.
True or False: Aerobic respiration produces less energy than anaerobic respiration.
False.
During which type of respiration is lactic acid produced?
Anaerobic respiration.
What is the energy currency of the cell produced during respiration?
ATP (adenosine triphosphate).
Fill in the blank: The process of breaking down glucose to release energy is called ______.
Respiration.
What is one advantage of aerobic respiration over anaerobic respiration?
It produces more energy (ATP).
Which type of respiration occurs in most animals and plants?
Aerobic respiration.
What happens to lactic acid in the body after exercise?
It is converted back to glucose in the liver.
Multiple Choice: Which of the following is NOT a product of aerobic respiration? A) Carbon Dioxide B) Glucose C) Water
B) Glucose.
What is the role of oxygen in aerobic respiration?
To act as the final electron acceptor in the electron transport chain.
Fill in the blank: Anaerobic respiration in muscles leads to the accumulation of ______.
Lactic acid.
True or False: All organisms can perform anaerobic respiration.
True.
