U1L7 Lactic Acid Fermentation

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, allowing organisms to generate energy in low-oxygen environments.

Front

What are the benefits of anaerobic respiration?

Back

It is a fast process, allows organisms to live in places with little oxygen, and evolved before aerobic respiration.

Front

Do all organisms perform cellular respiration?

Back

Yes, all organisms, including plants, perform cellular respiration to convert nutrients into energy.

Front

What causes muscle soreness after intense activity?

Back

Muscle soreness is caused by the accumulation of lactic acid in the muscles due to anaerobic respiration.

Front

How does an increase in oxygen levels affect cellular respiration?

Back

An increase in oxygen levels will increase the rate of cellular respiration.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is a metabolic process that converts glucose into lactic acid when oxygen is scarce, typically occurring in muscle cells during intense exercise.

Front

What is the primary substrate for lactic acid fermentation?

Back

The primary substrate for lactic acid fermentation is glucose.

Front

What role does NAD+ play in anaerobic respiration?

Back

NAD+ acts as an electron carrier, allowing glycolysis to continue by accepting electrons during the conversion of glucose to lactic acid.

Front

What happens to lactic acid after it is produced in muscles?

Back

Lactic acid can be converted back to glucose in the liver when oxygen becomes available.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) compared to anaerobic respiration, which occurs without oxygen.
