What else can I help you with?
What are 4 small molecules that can move easily through the phospholipid bilayer?
i do not know all four, but i know three are: O2 (Oxygen) CO2 (Cardon Dioxide) and H2O (Water)
What are plasma membranes permeable to?
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
What kind of things can pass through the phospholipid bilayer?
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.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in 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.
How are smaller molecules like o2 and co2 able to pass through the openings of the cell membrane?
Smaller molecules like O2 (oxygen) and CO2 (carbon dioxide) can pass through the cell membrane by a process called simple diffusion. This occurs because these nonpolar molecules can easily move through the lipid bilayer of the membrane, which is hydrophobic in nature. Their small size and lack of charge allow them to traverse the membrane without the need for transport proteins or energy input. As a result, they can enter and exit the cell freely, maintaining the necessary balance of gases for cellular processes.
Why can co2 and o2 cross the phospholipid bilayer without help from proteins?
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.
Can CO2 diffuse through the lipid bilayer?
Yes, carbon dioxide (CO2) can diffuse through the lipid bilayer of a cell membrane.

What moves through the lipid bilayer of a plasma membrane most rapidly K glucose an amino acid CO2 or starch?
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.
What are plasma membranes permeable to?
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
Biological membranes are normally permeable?

Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
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.
What kind of things can pass through the phospholipid bilayer?
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.
What does air or co2 have to pass through to get breathed out?
Air or CO2 must pass through the respiratory system, specifically the lungs. During exhalation, these gases move out of the lungs and are expelled from the body through the nose or mouth.

What types of substances pass easily through cell membranes?
If the substance is small and its nonpolar then ill be able to pass. For example O2 and CO2
