What else can I help you with?
During exercise muscle cells use what?
During exercise muscle cells use oxygen.
What happens in your muscle tissue and cells when the demand of oxygen is not met?
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
Fermentation in muscle cells produces?
Fermentation in muscle cells produces lactic acid. This happens when you have overworked your muscles, which can happen during exercise.
When you exercise vigorously glycogen is broken down in muscle cells providing energy to?
muscle cells.
Does muscle cells increase with exercise?
yes
Why exercise makes you stronger?
Exercise causes your muscle cells to widen and grow so that that muscle becomes bigger and stronger.
What happens to muscle cells or fibers when the body is inactive?
When the body is inactive, muscle cells or fibers undergo gradual atrophy, leading to a decrease in size and strength. This occurs due to a decrease in protein synthesis and an increase in protein breakdown. Regular exercise is necessary to maintain muscle mass and function.
Copmpared to other body cells a muscle cell is likely to have more of what organelles for energy?
Mitochondria. Muscle cells need more energy over a short period of exercise than most other cells. The cell uses mitochondria to transform food energy into a energy source it can use for its reactions.
An increase in the bulk of muscle cells that occurs as a result of exercise is known as what?
hypertrophy
A usual result of resistance exercise?
Existing muscle cells increase in diameter.
Under what condition are muscle cells produces?
Muscle cells are produced during development in the embryo from stem cells called myoblasts. Muscle growth can also occur through exercise or injury, where satellite cells are activated to differentiate into new muscle cells.
Which type of muscle cell exhibits a longer refractory period?
Cardiac muscle cells exhibit a longer refractory period compared to skeletal muscle cells. This is important in preventing tetanic contractions and ensuring that the heart muscle can effectively pump blood.
