Question

in this model of a cell, in which direction will co₂ move across the cell membrane? from left to right from right to left

Explanation:

CO₂ moves across the cell membrane by diffusion, from an area of higher concentration to an area of lower concentration. Without seeing the actual concentration levels in the model, we assume that cells produce CO₂ as a by - product of cellular respiration and release it outside the cell. So it generally moves from inside the cell (higher concentration) to outside the cell. If we assume left is inside and right is outside, it moves from left to right.

Answer:

from left to right
