Oxygen and carbon dioxide cross the plasma membrane by what process?

Answer 1

They are carried by the hemoglobin in your blood.

The red blood cells carry the carbon monoxide through the pulmonary artery from the heart to the lungs and from the heart the oxygen goes into the aorta to the rest of your body. == ==

Answer 2

Since Carbon dioxide and Oxygen are both gases, they just float right across. When a compound or molecule crosses a membrane with its concentration gradient, it's called Simple Diffusion. This is how most gases cross the plasma membrane.

Answer 3

carbon dioxide goes into pores in the under surface of the leaf, called stomata, and diffuse into the leafs tissues and oxygen exits through these pores aswell though this cannot happen when the stomata close up

Answer 4

When substances like co2 and o2 accumulate in high concentration inside the cell,the concentration of co2/o2 is low in the external environment as compared to the inside of the cell.co2/o2 moves from a region of high concentration(INSIDE OF THE CELL) to region of low concentration of co2/o2(OUTSIDE OF CELL), by the process of diffusion.

Answer 5

Because the cell walls of the Alveoli are only one cell thick both the Oxygen and Carbon Dioxide molecules can pass through very easily. Oxygen is passed from the Alveoli to the bloodstream to re-oxygenate the blood while Carbon Dioxide passes the opposite way to be exhaled. Think of a revolving door where O2 enters and CO2 exits.

Answer 6

The blood carries oxygen and carbon dioxide (as well as nutrients for your body) into and out of your body.

Answer 7

Simple diffusion. This involves dissolving across the phospholipid bilayer, the main component of plasma membranes.

Answer 8

The cell membrane is partially permeable - this means oxygen and carbon dioxide can pass through it.

Answer 9

diffusion

Answer 10

white blood cell
