Question

How many carbon dioxide molecules are inside and outside the cell at equilibrium?

a) Inside the cell: 1, Outside the cell: 1
b) Inside the cell: 2, Outside the cell: 2
c) Inside the cell: Equal to outside the cell
d) The number of molecules varies depending on cell size.

Answer 1

At equilibrium, the concentration of c) carbon dioxide molecules is the same inside the cell as it is outside, following the principle of diffusion across the cell membrane.

Step-by-step explanation:

The question 'How many carbon dioxide molecules are inside and outside the cell at equilibrium?' is addressing a concept in cellular biology related to the diffusion of molecules across cell membranes. The correct answer is c) Inside the cell: Equal to outside the cell, which reflects a state of equilibrium whereby the concentration of carbon dioxide molecules is the same on both sides of the cell membrane. The ratio of oxygen to carbon in compounds such as carbon monoxide and carbon dioxide follows fixed ratios, as seen in the formation of CO2 molecules from cellular respiration.
