Lactate (also known as lactic acid) and NAD+
Lactic acid
muscle cells
No, not all types of fermentation produce carbon dioxide (CO2). For example, alcoholic fermentation, which occurs in yeast, typically produces CO2 along with ethanol. In contrast, lactic acid fermentation, which occurs in certain bacteria and muscle cells, primarily produces lactic acid without generating CO2. Therefore, the type of fermentation determines whether CO2 is produced or not.
The type of fermentation that sometimes occurs in human muscle cells is Lactic Acid fermentation.
Alcoholic Fermentation
Human muscle cells undergo lactic acid fermentation in low oxygen conditions.
Lactic acid fermentation is a type of fermentation that sometimes occurs in humans. This process occurs in muscle cells when the oxygen supply is limited during intense exercise, leading to the production of lactic acid as a byproduct.
yeast
No, muscle cells do not reproduce in meiosis. Meiosis is a type of cell division that produces gametes (sperm and egg cells) for sexual reproduction, while muscle cells reproduce through a process called mitosis.
Cells that do not require oxygen go through anaerobic respiration, which is a form of cellular respiration that uses fermentation to turn energy into useful energy. There are two types of anaerobic respiration, lactic acid fermentation and alcohol fermentation. Muscle cells do this when they run out of oxygen and go through fermentation instead. The product of this type of fermentation from muscle cells is lactic acid. Lactic acid is toxic and causes soreness and fatigue. Anybody who has been sore after exercise has experienced lactic acid fermentation.
Lactic acid fermentation is an anaerobic process. This means that lactic acid is produced in the absence of oxygen. This usually occur in bacteria cells but can also occur in muscle cells.
Lactate fermentation and ethanol fermentation are both anaerobic processes that enable organisms to generate energy without oxygen by converting glucose into simpler compounds. They are similar in that both processes regenerate NAD+, allowing glycolysis to continue. However, they differ in their end products: lactate fermentation produces lactate, primarily in muscle cells and some microorganisms, while ethanol fermentation produces ethanol and carbon dioxide, primarily in yeast. Additionally, the pathways and enzymes involved in each fermentation type vary, reflecting the different organisms and conditions under which they occur.
