Why active transport is affected by changes in oxygen concentration but diffusion is not?
Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.
Asked in Blood, Respiratory System, Lungs
Why our body cells have a different oxygen concentration compared to the blood flowing to them from our lungs?
Diffusion from high concentration to low concentration. The oxygen concentration in the air in the lungs is higher than in the blood. The oxygen concentration in the blood is higher than in body cells. If these differences in concentration did not exist oxygen could not move from the air to the blood to body cells. While we are alive body cells consume some of the oxygen they receive, reducing their oxygen concentration and maintaining these differences. When we die the body cells quit consuming oxygen and over a period of time the levels of oxygen slowly begin evening out (however as blood no longer moves from the lungs to the body oxygen diffusion slows dramatically, leaving some body cells with much lower oxygen levels than would be normal).
How does oxygen pass from air in alveolus into blood?
Asked in Cardiovascular Health
How does oxygen pass from the air you breath into the tissues of the body?
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
What is the concentration of oxygen inhaled during oxygen therapy dependent upon?
Asked in Chemistry, Human Anatomy and Physiology
How much oxygen and carbon dioxide is there in the air?
Asked in Blood Vessels
What blood vessel has blood at high pressure but with a low oxygen concentration?
Asked in Human Anatomy and Physiology
What direction will oxygen diffuse?
Diffusion is when a molecules spread from an area of high concentration to an area of low concentration so the oxygen will move away from the other oxygen molecules that were in a high concentration to an area with a lower concentration. An example you would relate this to would be if you were to put a drop of food coloring into a glass of water.
