What else can I help you with?
What is the function role of t tubules?
Enhance cellular communication passage for nervous stimulation during muscle contraction.
What substsances are produced as waste in Muscle and must be removed?
During muscle metabolism, one of the waste products produced is lactic acid, which can build up during exercise and contribute to muscle fatigue. Additionally, carbon dioxide is produced as a byproduct of cellular respiration in muscles, and this waste gas is removed from the body through the lungs when we exhale.
Inability of muscle fibers to contract after a long period of contraction?
This is likely due to muscle fatigue, which happens when muscle fibers become depleted of energy sources like ATP needed for contraction. Accumulation of waste products like lactic acid and a decrease in calcium availability can also contribute to muscle fatigue. Rest and replenishing energy sources can help muscles recover and regain the ability to contract.
What are the product obtained during cellular anaerobic respiration human muscle cell-?
The product obtained during cellular anaerobic respiration human muscle cell water, energy and carbon dioxide.
When a muscle is being stimulated but is not able to respond due to oxygen debt the condition is called?
Fatigue
Why does the burning sensation associated with muscle fatigue occur due to the accumulation of?
The burning sensation during muscle fatigue happens because of the buildup of lactic acid in the muscles.
Does lactic acid cause muscle fatigue?
Yes, lactic acid can contribute to muscle fatigue during intense exercise.
How does the accumulation of lactic acid contribute to muscle fatigue during physical activity?
During physical activity, the accumulation of lactic acid in muscles can lead to muscle fatigue. This happens because lactic acid buildup can interfere with the muscles' ability to contract efficiently, causing them to feel tired and weak.
How does calcium affect muscle fatigue?
Muscle fatigue results from relative deficit of ATP.calium does not affect muscle fatigue

How are ATp levels affected by muscle fatigue?
There has been no universal mechanism found to explain skeletal muscle fatigue. With the onset of intense exercise, muscle force has been shown to fall, which is often illustrated as a sign of fatigue. As ATP supplies the immediate energy to the muscle cell, the relationship between ATP and fatigue has been a topic of interest among researchers. During muscle contraction the majority of ATP is used for cross bridge cycling, ion pumps and transporters, and chemical signalling cascades. A fall in [ATP] would result in the development of rigor and goes against the viability of the cell. It is proposed that whole muscle [ATP] does not fall with repeated contraction, though there may be differences in [ATP] between fiber types with fatigue. Rather, fatigue is a protective mechanism by the muscle to preserve [ATP] accomplished by down regulating cellular processes that use ATP for energy
What are the product obtained during cellular anaerobic respiration human muscle cell-?
The product obtained during cellular anaerobic respiration human muscle cell water, energy and carbon dioxide.
What happens to the lactic acid created during fermentation in human muscle cells?
During fermentation in human muscle cells, lactic acid is produced as a byproduct. This lactic acid is eventually broken down and converted back into energy by the body's cells, helping to replenish energy stores and reduce muscle fatigue.
What is the most direct cause of muscle fatigue during exercise in the heat?
The most direct cause of muscle fatigue during any exercise in direct heat is dehydration of the body system as well as excessive build up of lactic acid.
What happens to force production over time in fatigue?
Force production decreases over time in fatigue due to a combination of factors such as muscle damage, depletion of energy stores, and impaired neural drive. This decline in force production can lead to reduced performance and muscle fatigue.
