CO2 would move most rapidly through the lipid bilayer of a plasma membrane due to its small size and non-polar nature, allowing it to pass through freely via simple diffusion. Glucose, amino acids, and starch are larger molecules that would require specific transport proteins or channels to facilitate their passage through the lipid bilayer.
Carbon dioxide (CO2) and oxygen (O2) are small, non-polar molecules that can diffuse across the phospholipid bilayer due to their size and hydrophobic nature. This allows them to pass through the lipid core of the membrane without the need for specific transport proteins.
Small, nonpolar molecules such as oxygen and carbon dioxide would likely move through the lipid bilayer of a plasma membrane most rapidly due to their ability to dissolve in the hydrophobic core of the membrane.
Oxygen and carbon dioxide are two small molecules that can move across cell membranes using simple diffusion. This process occurs because these molecules are small enough and nonpolar, allowing them to pass through the lipid bilayer without the need for a transport protein.
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.

Lipid-soluble molecules, such as oxygen, carbon dioxide, and steroid hormones, readily diffuse through plasma membranes. Water, however, requires small pores called aquaporins therefore it is aided.
Although some small molecules including oxygen, water and co2 are able to diffuse through it, the phospholipid bilayer forms a barrier to most hydrophilic molecules and ions. --Biology wit physiology, Life on Earth 5th edu - Ausesrik, Byers
Oxygen (O2) would diffuse from alveoli in the lungs into the blood, while carbon dioxide (CO2) would diffuse from the blood into the alveoli for elimination from the body during internal respiration.
CO2 diffuses faster than oxygen because it is a smaller molecule and has a lower molecular weight, allowing it to move more rapidly through cell membranes and other barriers. Additionally, CO2 has a higher solubility in water compared to oxygen, further aiding its diffusion.
The plants use CO2 from air for photosynthesis. The air entering into its leaves through stomata comes in contact with photosynthetic cells and diffuse CO2 for assimilation to form carbohydrates.
