What type of transport is usually happening when oxygen is absorbed into cells?

Final answer: Oxygen is typically absorbed into cells through a process called passive diffusion. It primarily binds with hemoglobin, a protein within red blood cells, in order to be transported to necessary tissues throughout the body. Explanation: The type of transport typically happening when oxygen is absorbed into cells is passive diffusion. In our lungs, oxygen diffuses across the alveoli and enters into the bloodstream. From here, 98.5 percent of the oxygen binds to a protein called hemoglobin within red blood cells (erythrocytes) for transport to the tissues where it is needed. Each hemoglobin molecule has the capacity to bind up to four oxygen molecules. Hemoglobin, which contains iron, forms a molecule called oxyhemoglobin when it binds to oxygen. This oxyhemoglobin is responsible for the bright red color of oxygenated blood. At the tissue level, oxygen is then released from the hemoglobin due to the varying needs of the surrounding tissues. This cycle continues to ensure adequate oxygen supply throughout the body. It's important to note that while some small organisms rely on diffusion alone for oxygen transport, larger organisms have evolved specialized respiratory and circulatory systems to help deliver oxygen effectively.

The type of transport that usually occurs when oxygen is absorbed into cells is passive diffusion. Passive diffusion is the mode of transport that typically takes place when oxygen is taken up by cells. Passive diffusion is a type of movement that takes place along a gradient of concentration, moving substances from one area of higher concentration to another without the need of energy. In order for cells to absorb oxygen, oxygen molecules must permeate past the cell membrane. Compared to the lower concentration inside the cells, the concentration of oxygen is higher in the external environment, such as the lungs or bloodstream. Until equilibrium is attained, this concentration gradient permits oxygen to passively permeate from locations of greater concentration to areas of lower concentration (the cells). The movement of oxygen and other small molecules across cell membranes via passive diffusion is a crucial process that enables oxygen to reach the cells and promote cellular respiration and energy production.
