Anaerobic respiration is a type of cellular respiration that occurs without oxygen.
What is the primary purpose of anaerobic respiration?
To break down glucose to release energy when oxygen is not available.
Where does anaerobic respiration occur in cells?
In the cytoplasm of cells.
What are the end products of anaerobic respiration in animals?
Lactic acid.
What are the end products of anaerobic respiration in yeast?
Ethanol and carbon dioxide.
How does anaerobic respiration compare to aerobic respiration in terms of energy production?
Anaerobic respiration produces less energy than aerobic respiration.
How much ATP is produced during anaerobic respiration?
2 ATP molecules.
What is the overall equation for anaerobic respiration in humans?
Glucose → 2 Lactic Acid + 2 ATP.
What causes muscle fatigue during intense exercise?
The buildup of lactic acid during anaerobic respiration.
What is the initial step in anaerobic respiration in yeast?
Glycolysis, breaking down glucose to pyruvate.
What is the main application of alcoholic fermentation in yeast?
It is crucial in brewing and baking industries.
What is the role of carbon dioxide in bread making?
Carbon dioxide produced by yeast fermentation makes the dough rise.
What are some applications of anaerobic respiration in the food industry?
It is used in bread making, brewing, and yogurt and cheese production.
How does anaerobic respiration contribute to biofuel production?
Ethanol from yeast fermentation is used as a renewable fuel.
What is anaerobic digestion and its significance?
Anaerobic digestion breaks down organic waste and produces biogas, which can be used as fuel.
What is the main byproduct of anaerobic digestion?
Biogas, mainly methane.
Which type of anaerobic respiration is suitable for producing renewable fuel from corn?
Alcoholic fermentation by yeast.
What is the difference between lactic acid fermentation and alcoholic fermentation?
Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide.
How does anaerobic respiration allow organisms to survive in low-oxygen environments?
It enables them to produce energy without the need for oxygen.
What can be used as a renewable energy source?
Corn can be used as a renewable energy source.
What is the process suitable for producing renewable fuel from corn?
- Alcoholic fermentation by yeast
- Converts sugars in corn to ethanol
- Ethanol is a common biofuel
How does lactic acid fermentation differ from alcoholic fermentation in terms of products and applications?
Lactic acid fermentation produces lactic acid for food products, while alcoholic fermentation produces ethanol for biofuels and beverages.
What are the main products and applications of different types of anaerobic respiration?
- Lactic acid fermentation:
- Produces lactic acid
- Used in yogurt production
- Alcoholic fermentation:
- Produces ethanol
- Used in brewing beer and biofuel production
- Anaerobic digestion:
- Produces biogas (mainly methane)
- Used in waste treatment and renewable energy generation
How much ATP is produced during lactic acid fermentation per glucose molecule?
Approximately 2 ATP molecules are produced during lactic acid fermentation per glucose molecule.
Which product is NOT typically produced during lactic acid fermentation?
Ethanol is NOT typically produced during lactic acid fermentation.
What does lactic acid fermentation convert milk sugars into?
Lactic acid fermentation converts milk sugars into lactic acid.
In which industry is lactic acid fermentation most commonly used?
Lactic acid fermentation is most commonly used in the food industry, particularly for dairy products.
What is the main product of lactic acid fermentation?
The main product of lactic acid fermentation is lactic acid.
What type of anaerobic respiration is responsible for the production of yogurt?
Lactic acid fermentation is responsible for the production of yogurt.
What does alcoholic fermentation produce besides ethanol?
Alcoholic fermentation also produces carbon dioxide.
What is the main product of alcoholic fermentation that makes it useful for biofuel production?
Ethanol is the main product of alcoholic fermentation that makes it useful for biofuel production.
What is lactic acid fermentation primarily associated with?
Lactic acid fermentation is primarily associated with human muscles during intense exercise and the production of foods like yogurt and some cheeses.
