How does exercise Increased number of mitochondria?

Mitochondria make the energy in your body. During exercise you need more energy so you need more energy "factories"


Does the tidal volume increase due to acute effects of exercise?

Yes, during exercise and increase in ventilation occurs primarily through an increase in tidal volume (i.e the volume of air taken in and out).


How many mitochondria are there in skeletal muscle?

It depends on the type of skeletal muscle. Slow and fast oxidative fibers (type I and type IIa) may have many mitochondria. Fast glycolytic fibers (type IIx/IIb) have very few mitochondria. This is because in fast glycolytic fibers (type IIx/IIb) ATP can be produced outside of the mitochondrion in the cytosol of the cell due to high concentrations of glycolytic enzymes present in these fibers. In contrast, in oxidative fibers ATP is produced mostly within the mitochondrion, so more mitochondria are needed to to produce large amounts of ATP. Also, the number of mitochondria in these cells can increase with adaptations to exercise conditioning.


Why would a Heart beat hard?

The heart beat can increase due to stress and exercise. There are many other factors that can increase heart rate.


Does hemoglobin's affinity for oxygen increase or decrease with exercise?

It decreases due to the increase in carbon dioxide in the blood. This causes more oxygen to be uploaded to the tissues


Growth due to an increase in cell number is called?

Growth that is due to an increase in cell number results from an increased rate of mitotic cell division and is termed hyperplasia. Consequently, growth of a tissue or organ due to an increase in cell size is termed hypertrophy.


All eukaryotes have mitochondria due to what?

No, there are some eukaryotic protists that don't have mitochondria.


Is a general increase in the bulk of a body part due to an increase in the size but not in the number of cells?

Hypertrophy


What effects does exercise have on tidal volume?

The effects that exercise have on tidal volume is that they cause an increase to in tidal volume. This is due to the faster breathing in which allows the lungs to bring in more oxygen.


Why do bone have increased calcium and phosphate levels due to exercise?

This is a good question! The calcium and phosphate level increase due to exercise. This is physiological response to stress of exercise. Your bones and muscles develop due to exercise. The bones becomes stronger and stronger as you give more and more stress to them. The stress lines also change as per requirement of the stress. Your bones get weak, when you put a plaster for fracture. This happens due to disuse of the bones.


What can the breathing rate increase to during exercise?

When we take exercise our body needs more oxygen .Our normal breathing rate do not fulfill the oxygen requirement due to which breathing rate is increased.


What happens if mitochondria are absent?

If there is no mitochondria in the cell of an organism then there will be no energy in the cell due to the mitochondria being the power house of the cell is absent. Basically, they break down food particles in the cell and turn it into ATP for the body to use.So if there would be no mitochondria there will be no use of eating food.
