Osmosis refers to the movement of water. Gases such as oxygen and CO2 move across the membrane by simple diffusion.

∙ 16y agoOxygen and Water pass through the cell membrane by simple osmosis. Glucose transportation through the membrane requires the involvement of insulin.

What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.

Water passes through a cell membrane by?
What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
What best describes the general direction of diffusion across the membrane of this cell?
Carbon dioxide would diffuse out of the cell
How do substance like co2 and water move in and out of the cell?
Carbon dioxide is a small nonpolar molecule which means that it can easily diffuse through the lipid bilayer of the cell membrane. Carbon dioxide moves from an area of high concentration to an area of low concentration. Diffusion is passive transport (no ATP required). Water is a polar molecule but it is pretty small so it can still dissolve through the lipid bilayer into the cell. The movement of water from an area of lower solute concentration to an area of higher solute concentration across a semipermeable membrane is called osmosis. Aquaporins are small water channels embedded in the lipid bilayer. These protein water channels provide a hydrophilic (polar) tunnel through the lipid bilayer for the fast movement of water across the membrane.. Aquaporins are a form of facilitated diffusion (diffusion with "help"). Osmosis and facilitated diffusion are forms of passive transport.
What passive process do cells use to pass oxygen and carbon dioxide across the cell membrane?
its due to osmosis
What material diffuses across the cell membrane during osmosis?
Osmosis is the movement of WATER from an area of high concentration to an area of low concentration through a semi-permeable membrane. So water is exchanged during osmosis.
What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.

What two important gases diffuse across the respiratory membrane?
oxygen and carbon dioxide
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 causes oxygen to enter and carbon dioxide to leave the capillaries?
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
What best describes the general direction of diffusion across the membrane of this cell?
Carbon dioxide would diffuse out of the cell
Why are the alveoli sometimes called respiratory membrane?
The alveoli are sometimes refer to as the respiratory membrane. This due to the transfer of gases that occurs between the epithelium (the membrane) and the capillaries (the blood). When Oxygen and carbon dioxide transfer across this membrane through diffusion Oxygen goes into the blood and Carbon dioxide is diffused out into the Alveoli.
How an amoeba exchanges oxygen and carbon dioxide gases with its surroundings?
diffusion across their body surface (cell surface membrane)
What organ does the oxygen-carbon Dioxide take place?
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
