What else can I help you with?
Through what structure does water oxygen and carbon dioxide can enter a cell?
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
What membrane of the red cell will allow water oxygen carbon dioxide and glucose to pass through?
Plasma membrane
Gas is carried mostly by the plasma?
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
Which ions are permeable to phospholipids that make up the plasma membrane?
Small, uncharged molecules like oxygen and carbon dioxide are permeable to phospholipids in the plasma membrane, while ions such as sodium (Na+), potassium (K+), and chloride (Cl-) are not permeable due to their charge.
What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely dissolve through the plasma membrane are generally small and nonpolar molecules, such as oxygen, carbon dioxide, and ethanol. These molecules are able to pass through the lipid bilayer of the plasma membrane without requiring a specific transport protein.
What process does oxygen and carbon dioxide use to cross the plasma membrane?
diffusion
Through what structure does water oxygen and carbon dioxide can enter a cell?
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
What membrane of the red cell will allow water oxygen carbon dioxide and glucose to pass through?
Plasma membrane
The passively diffuses oxygen and carbon dioxide in and out of the cell. cell wall plasma membrane nucleus protoplasm?
The plasma membrane is responsible for the passive diffusion of oxygen and carbon dioxide into and out of the cell. It regulates the movement of molecules in and out of the cell, allowing for gas exchange.
What determines whether carbon dioxide is absorbed or released by blood?
The rate at which carbon dioxide enters the cell is determined by the concentration of carbon dioxide on each side of the membrane. Carbon dioxide crosses the plasma membrane by simple diffusion.
Name two gases found in plasma?
The carbon dioxide and oxygen are the two main gases in plasma. When blood travels to the lungs the concentration of these two gases changes.
Gas is carried mostly by the plasma?
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
Three kinds of materials that are carried in plasma?
Oxygen, carbon dioxide, and food
Which ions are permeable to phospholipids that make up the plasma membrane?
Small, uncharged molecules like oxygen and carbon dioxide are permeable to phospholipids in the plasma membrane, while ions such as sodium (Na+), potassium (K+), and chloride (Cl-) are not permeable due to their charge.
Is CO2 more soluble in plasma and alveolar fluis than the oxygen?
No, oxygen is more soluble in plasma and alveolar fluid than carbon dioxide. However, carbon dioxide is transported in the blood more efficiently as bicarbonate ions and dissolved carbon dioxide, rather than in its gaseous form like oxygen.
Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Small, nonpolar molecules such as oxygen and carbon dioxide would likely move through the lipid bilayer of a plasma membrane most rapidly due to their ability to dissolve in the hydrophobic core of the membrane.
Is oxygen more soluble in plasma than carbon dioxide?
When matter is subjected to the conditions necessary to create plasma it disrupts molecular bonds. Since CO2 has oxygen atoms bonded to the carbon, when it is ionized into plasma, the bonds will be disrupted and the plasma will contain separate carbon and oxygen atoms. A very small fraction of the CO2 might persist as molecular ions but most of them would be CO ions, not the full CO2.
