⚡️Anaerobic processes allow cells to generate ATP without oxygen.
🧪Fermentation and anaerobic respiration are two types of anaerobic pathways.
🍺Lactic acid fermentation produces lactic acid, while alcohol fermentation produces ethanol.
🔥Both fermentation and anaerobic respiration help cells regenerate NAD+ to continue glycolysis and ATP production.
💪Anaerobic pathways are essential for organisms that don't require oxygen, such as certain bacteria and yeast.
How do fermentation and anaerobic respiration differ?
—Fermentation is the process where pyruvate is converted into lactic acid or ethanol, while anaerobic respiration resembles aerobic respiration but occurs without oxygen.
Why do cells perform fermentation?
—Cells perform fermentation to regenerate NAD+ in the absence of oxygen, allowing them to sustain ATP production through glycolysis.
Which type of fermentation occurs in human muscle cells?
—Lactic acid fermentation occurs in human muscle cells during intense exercise when oxygen availability is limited.
What is the impact of lactic acid fermentation on muscles?
—Lactic acid fermentation leads to the accumulation of lactic acid in muscle cells, causing soreness and fatigue.
Which organisms can perform alcohol fermentation?
—Yeast and certain bacteria can perform alcohol fermentation, a process used to make alcoholic beverages.
