What will eventually happen to the concentration of particles inside and outside the cell?
If the number of particles inside the cell is higher than the number of particles outside of the cell a hypotonic system has been established. Again the water molecules move more easily than the particles inside the cell. With the concentration higher inside of the cell, the water will move into the cell.
Will water go in or out of the cell?
In general, net movement of water into or out of cells is negligible. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn’t lose or gain water because equal amounts go in and out.
What cell has no cell wall?
Examples of bacteria that lack a cell wall are Mycoplasma and L-form bacteria. Mycoplasma is an important cause of disease in animals and is not affected by antibiotic treatments that target cell wall synthesis.
Is the process by which oxygen is moved into and carbon dioxide is moved into a cell?
simple diffusion
How does oxygen get into a cell?
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.
How many cell membrane does oxygen pass through?
two cellular membranes
What are 3 ways for materials to move in and out of cells?
diffusion, osmosis and active transport are three similar chemical methods by which single molecules or very small structures are moved across membranes or relatively short distances, often within or between cells.
How does oxygen transport and gas exchange work throughout the body?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
Why is it important to break down glucose in small steps?
The series of steps where glucose is broken down to release energy begins with a metabolic pathway called glycolysis. If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen).
