What are two examples of passive transport?
Two examples of passive transport are simple diffusion, where molecules move across a membrane from an area of high concentration to low concentration, and facilitated diffusion, where molecules move across a membrane with the help of specific transport proteins.
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
Oxygen and carbon dioxide are exchanged in the lungs through diffusion. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their concentration gradients. This process does not involve active transport, filtration, or osmosis.
What is it called when a molecule moves across the membrane without using energy?
It's called passive transport. An example of passive transport is O2 (Oxygen), and CO2 (Carbon Dioxide). They both use a "key" to get into the cell, in this case, the key is the chemical formula of O2. Things without a key require the cell to use energy to use endocytosis and exocytosis. (At least that's what my 8th grade science teacher told me!)
What is the most important protein in the physiologically transport of carbon dioxide by blood?
The most important protein involved in the transport of carbon dioxide by blood is hemoglobin. Hemoglobin binds to carbon dioxide in red blood cells and helps transport it from tissues to the lungs, where it can be exhaled.
How both passive transport and active transport are necessary for photosynthesis to occur explain?
Basic photosynthesis equation is Water + Carbon Dioxide --> Glucose + Oxygen -Water is absorbed by the roots via osmosis (passive transport), moves through the xylem and is absorbed into cells where it is needed via osmosis again -CO2 from the high concentration in the atmosphere to the low concentration in the plants cells through the stomata. It is always being used up to synthesis glucose so the lower concentration is maintained -Glucose is usually converted into sucrose (a relatively large molecule) which then requires active transport to cross the plasma mebrane, and into the phloem tubes to a storage site -I would imagine oxygen would diffuse out via the same channels that CO2 came in
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide can diffuse passively through the cell membrane due to its small size and nonpolar nature. Water molecules can pass through the membrane via osmosis, a type of passive transport. Sodium ions are transported against their concentration gradient through active transport processes such as sodium-potassium pumps that require ATP for energy.
A molecule that can diffuse freely through a phospholipid bilayer is probably?
By Passive transport i can onlythink of glucose, but by active transport material like water, carbon dioxide, amino acids, sodium and potasium and of course oxygen! :)
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
What are two examples of passive transport?
Two examples of passive transport are simple diffusion, where molecules move across a membrane from an area of high concentration to low concentration, and facilitated diffusion, where molecules move across a membrane with the help of specific transport proteins.
What passes through a cell using passive transport?
Small uncharged molecules like oxygen and carbon dioxide can pass through a cell using passive transport, which includes processes like diffusion and facilitated diffusion. Water can also pass through a cell membrane through a process known as osmosis.
How does passive transport affect red blood cells?
Passive transport allows substances like oxygen and carbon dioxide to move freely across the cell membrane of red blood cells without the need for energy. This process helps maintain the proper balance of these gases, allowing red blood cells to efficiently transport oxygen to tissues and remove carbon dioxide from the body.

Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their concentration gradients.

What is a nutrient that uses passive transport?
Some examples of nutrients that require only passive transport through cells would be small molecules of glucose, oxygen, amino acids, carbon dioxide, and water.

What kind of substances are likely to move via passive transport through phospholipod bilyer?
Small, non-polar molecules like oxygen and carbon dioxide are likely to move via passive transport through a phospholipid bilayer. These molecules can easily diffuse across the lipid bilayer due to their size and hydrophobic nature. Larger or polar molecules generally require other mechanisms such as facilitated diffusion or active transport to cross the membrane.
Which process drives the gas exchange from the alveoli to the capillaries?
Diffusion is the process that allows the exchange of oxygen and carbon dioxide in the alveoli. This process is one of passive transport.
