What else can I help you with?
Water passes from the tissue fluids into the blood capillaries mainly because?
lymph blood has a higher protein concentration than the tissue fluids
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
What makes oxygen pass into the capillaries that surround these sacs?
Diffusion. O2 moves from an area of higher concentration to a lower concentration.
What does the oxygen pass out from the bloodstream?
Oxygen diffuses from red blood cells in the bloodstream into body tissues through capillaries. It moves from areas of higher concentration in the blood to areas of lower concentration in the tissues, where it is used for cellular respiration.
When molecule enters through the cell through protein pump is it classified as active or passive transport?
When a molecule enters the cell through a protein pump, it is classified as active transport. This process requires energy, typically in the form of ATP, to move molecules against their concentration gradient, from areas of lower concentration to higher concentration. In contrast, passive transport does not require energy and occurs along the concentration gradient.
Is gluten higher in level in protein flour?
Yes, gluten concentration would be higher in high protein flower because the gluten is the main protein in flour.
Would the concentration of a diluted protein shake with an absorbance value of 70mg ml be darker than a protein concentration of 15mg ml?
Yes, the diluted protein shake with an absorbance value of 70mg/ml would appear darker than the protein concentration of 15mg/ml. Higher absorbance values indicate a higher concentration of solute present in the solution, leading to a darker appearance.
What pathway does oxygen leave capillaries to supply body tissue?
Oxygen leaves capillaries through a process called diffusion. This occurs when oxygen, present in higher concentrations in the capillaries, moves into the surrounding tissues where the concentration is lower. The thin walls of the capillaries facilitate this exchange, allowing oxygen to enter cells and support cellular respiration. Concurrently, carbon dioxide produced by cells diffuses back into the capillaries to be transported away for exhalation.
How do water molecules move through the cell membrane during omosis?
With a specific channel protein called aquaporins.
How does material get from inside capillaries to body cells?
Material moves from inside capillaries to body cells primarily through a process called diffusion. Oxygen and nutrients, which are in higher concentration in the blood, diffuse across the capillary walls into the surrounding tissues where their concentration is lower. Additionally, small openings in the capillary walls allow for the passage of larger molecules and fluids through filtration and osmosis. This exchange of materials is crucial for cellular function and overall homeostasis.
Why does oxygen diffuse in and carbon dioxide diffuse out?
In the alveoli, oxygen diffuses into the blood that the capillaries carry due to a concentration gradient that exists there as oxygen conc is higher in the alveolar sacs than in the blood capillaries. Similarly carbon dioxide diffuses out of the blood capillaries into the alveolar sacs down the concentration gradient. The constant flow of blood is there to ensure this concentration gradient is established at all times.
Does simple diffusion require a helper protein?
No, simple diffusion does not require a helper protein. It is the passive movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration, relying on the concentration gradient. This process occurs directly through the lipid bilayer of the membrane for small, nonpolar molecules like oxygen and carbon dioxide.
