Anearobic Respiration Flashcards
What is anaerobic respiration?
Anaerobic respiration is a type of respiration that occurs without oxygen.
True or False: Anaerobic respiration is less efficient than aerobic respiration.
True
What is the main energy currency produced during anaerobic respiration?
Adenosine triphosphate (ATP)
Fill in the blank: In anaerobic respiration, glucose is partially broken down into _______.
lactic acid or ethanol
Which organisms primarily utilize anaerobic respiration?
Certain bacteria, yeast, and muscle cells in animals.
What are the two main types of anaerobic respiration?
Lactic acid fermentation and alcoholic fermentation.
True or False: Anaerobic respiration produces more ATP than aerobic respiration.
False
What is lactic acid fermentation?
A process that converts glucose into lactic acid and ATP without oxygen.
In which type of cells does lactic acid fermentation occur?
Muscle cells under low oxygen conditions.
What is alcoholic fermentation?
A process that converts glucose into ethanol, carbon dioxide, and ATP.
Which organism is commonly associated with alcoholic fermentation?
Yeast
What byproduct is produced during alcoholic fermentation?
Carbon dioxide
Fill in the blank: Anaerobic respiration occurs in the _______ of the cell.
cytoplasm
True or False: Anaerobic respiration can occur in the presence of oxygen.
False
What is the primary advantage of anaerobic respiration?
It allows organisms to produce energy in environments lacking oxygen.
Which process is used by muscle cells during intense exercise when oxygen is scarce?
Lactic acid fermentation
What is the role of NAD+ in anaerobic respiration?
NAD+ acts as an electron carrier and is regenerated during fermentation.
True or False: Anaerobic respiration can lead to muscle fatigue.
True
What is the maximum yield of ATP from one glucose molecule during anaerobic respiration?
2 ATP
Fill in the blank: The process of converting pyruvate into lactic acid is called _______.
lactic acid fermentation
What is a key difference between anaerobic and aerobic respiration?
Anaerobic respiration does not require oxygen, while aerobic respiration does.
In which conditions would an organism switch from aerobic to anaerobic respiration?
When oxygen levels are low or absent.
What type of fermentation occurs in yeast?
Alcoholic fermentation
What are the end products of anaerobic respiration in yeast?
Ethanol and carbon dioxide
