Which type of molecule forms the cell membrane?
Phospholipids are the primary type of molecule that forms the cell membrane. They have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to arrange in a bilayer to create the cell membrane.
How many cells does an oxygen molecule have to pass through to get from an alveolus into the blood?
An oxygen molecule must pass through four cell layers to move from an alveolus into the bloodstream: the alveolar epithelial cells, the capillary endothelial cells, and their basement membranes. This process is essential for oxygen exchange in the lungs.
Which molecule in animal plasma membranes stiffens and strengthens the membrane?
Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.
What is the diameter of hemoglobin?
The diameter of Hb molecule is app. 5.5 nm, and that is larger than a glucose molecule.
Does sugar diffuse through the cell membrane?
No. Only non-polar, small molecules can pass through a membrane by simple diffusion. A sucrose molecule is too large a molecule to pass through a membrane by simple diffusion, however, it can pass through a plasma membrane (but not any artificial membranes like Visking tubings) by facilitated diffusion, i.e. through transport proteins(specific carriers for sucrose) embedded in the membranes. ! =)
How does carbon monoxide enter and exit cell membranes so quickly?
Carbon monoxide is a small, non-polar molecule that can diffuse rapidly through cell membranes. It passes through the lipid bilayer of the membrane due to its small size and non-polar nature, allowing it to move quickly in and out of cells. Additionally, carbon monoxide has a high affinity for hemoglobin, which helps facilitate its transport across cell membranes.

What is the length of hemoglobin molecule?
6.8*10-6mm is the length of a hemoglobin molecule

What is the most common type of molecule present in the bacteria cell membranes?
Phospholipids are the most common type of molecule present in bacterial cell membranes. They have a hydrophobic tail and a hydrophilic head, which allows them to form a lipid bilayer that makes up the cell membrane.
What type of molecule is embedded in cell membranes?
Proteins are often found embedded in the cell membrane. These proteins are called transmembrane or inter-membrane proteins.Cholesterol molecules are also found embedded in the hydrophobic interior of the cell membrane in many species

What lipid molecule makes up 50 percent of the cell membranes?
A phospholipid bilayer makes up most of the cell membrane
Is the B subunit of the hemoglobin A molecule a complete DNA molecule?
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
A fully functional molecule of hemoglobin is what kind of protein structure?
The structure of the hemoglobin in a molecule is the quaternary structure.
What substance is transported by hemoglobin?
The hemoglobin molecule is what the oxygen molecule will attach to in the red blood cell.
Hemoglobin is what type of molecule?
A protein Molecule
