diffussion of oxyzen means dissociation curve .oxyzen diffussion depends on concentration of corbon dioxide concentration and bmr .if corbon dioxide concentration is increased the diffussion is also increased. if bmr is also high the diffussion of oxyzen in blood is also increase
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
protiens
Things that aren't charged. Charged particles can't cross the hydrophobic tails, but are attracted to the outward-facing hydrophilic phosphate heads. Things that are charged can still diffuse into the cell, but it must be facilitated by proteins present within the cell membrane.Oxygen and carbon dioxide are some examples of things that can freely diffuse across the cell membrane, water and ions are some example of things that must be facilitated by protein channels.
No, nonliving things do not have cells. Cells are the basic structural and functional units of living organisms. Nonliving things do not exhibit the characteristics of life, such as growth, metabolism, and reproduction, which are dependent on the presence of cells.
Oxygen diffuses through two layers of cells: the alveolar epithelial cells lining the lung air sacs and the capillary endothelial cells before it reaches a red blood cell in the pulmonary capillaries.
The molecules of food and oxygen diffuse into cells. oh and btfw co2 and waste chemicals diffuse ut of cells. im in year 3
Oxygen and carbon dioxide

Why not? It is like asking why are you born with hands and legs
Blood -> plasma -> extracellular fluid -> cells.
veins
YES
Proteins are keep the cell going. They have many jobs to do one of which give the cell the energy to do what the cell is program to do in the body. So no proteins are not to large to diffuse in cells

Oxygen and carbon dioxide are substances that diffuse during respiration in living organisms. Oxygen diffuses into cells for cellular respiration, while carbon dioxide diffuses out of cells as a waste product.
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
The function is to allow CO2 and O2 to diffuse to and from all cells.
