is temporary, is due to oxygen deficiency, and regenerates NAD
Muscle cells in oxygen deprivation convert pyruvate to lactate through a process called anaerobic glycolysis. This allows for the generation of ATP in the absence of oxygen, but results in the build-up of lactate in the muscles, leading to muscle fatigue and soreness.
No, lactate and ethanol are two possible products of glycolysis in anaerobic conditions. Some organisms produce lactate, some produce ethanol. You, for example, produce lactate. Yeast produces ethanol.
Lactate accumulates because of the lack of available oxygen in the muscles. In anaerobic conditions, the pyruvate produced by glycolysis is reduced to lactate via lactate dehydrogenase (while also oxidizing a single molecule of NADH to regenerate NAD+). NAD+ is a very important molecule and must readily be available in the cytoplasm in order for glycolysis to proceed.

No, skeletal muscle cells do not have glycosomes. Glycosomes are specialized organelles found in certain types of cells, particularly in protists and some parasites, where they are involved in glycolysis. Skeletal muscle cells primarily rely on mitochondria for energy production.
The lactate is taken to the liver and converted back to pyruvate.
Muscle cells running low on ATP, muscle cells running low on O2, and lactate build-up in the muscle cells.
Lactate is the end-product of anaerobic respiration in exercising muscle. It is produced when the demand for energy exceeds the supply of oxygen to the muscle cells, leading to the conversion of pyruvate to lactate.
Muscle cells in oxygen deprivation convert pyruvate to lactate through a process called anaerobic glycolysis. This allows for the generation of ATP in the absence of oxygen, but results in the build-up of lactate in the muscles, leading to muscle fatigue and soreness.
In oxygen deprivation, muscle cells convert pyruvate into lactate through anaerobic glycolysis. This conversion allows the cells to regenerate NAD+ from NADH, enabling glycolysis to continue and produce ATP without oxygen. This helps sustain energy production in the absence of sufficient oxygen supply.
No, lactate and ethanol are two possible products of glycolysis in anaerobic conditions. Some organisms produce lactate, some produce ethanol. You, for example, produce lactate. Yeast produces ethanol.

Lactate threshold is caused when lactate production exceeds lactate clearance during exercise or increasing intensity.
The Cori cycle is metabolic interaction between the liver and muscle tissue. gluconeogenesis is occurring in the liver while glycolysis is happening in the muscle tissue. The two fates of the glucose undergoing glycolysis in the muscle tissue is ultimate breakdown into lactate and alanine.
Fermentation in muscle cells produces lactic acid. This happens when you have overworked your muscles, which can happen during exercise.
Yes, highly aerobic muscle fibers and other tissues can utilize lactate as an energy source. Lactate is produced during anaerobic metabolism but can be converted back to pyruvate, which then enters the aerobic metabolic pathway for ATP production. Additionally, certain tissues, such as the heart and brain, can effectively use lactate in times of increased energy demand or limited oxygen availability. This process is part of the lactate shuttle theory, which highlights the role of lactate in energy metabolism across different tissues.
