What are two examples of passive transport?
- Oxygen -Carbon Dioxide -Osmosis of water
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
osmosis
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
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!)
Erythrocytes transport oxygen and serve to?
It is to carry oxygen from the lungs to tissue around the body.
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide cannot be transported across the membrane by passive transport. However, water and sodium ions can be transported using passive transport.
What are two examples of passive transport?
- Oxygen -Carbon Dioxide -Osmosis of water
What passes through a cell using passive transport?
oxygen, carbon dioxide, and water molecules
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! :)
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.
How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
They move via diffusion across a gradient.
The cellular transport process by which carbon dioxide enters a leaf and by which water vapor and oxygen exit is a osmosis b active transport c co- transport d diffusion e bulk flow?
a
What drives the movement of carbon dioxide from tissue into the bloodstream?
Movement of carbon dioxide is driffen by osmosis from and to the tissue and bloodstream. Also active transport can be used. Amount of CO2 present is monitored by means of the pH of your blood as dissolved CO2 is acidic.
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.
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
osmosis
What do you know about hemoglobin?
which permits them to transport oxygen and carbon dioxide
Does blood transport carbon dioxide and waste to each cell?
No, carbon dioxide and waste are transported by the blood AWAY from each cell.
