A molecule that can diffuse freely through a phospholipid bilayer is probably?
By Passive transport i can onlythink of glucose, but by active transport material like water, carbon dioxide, amino acids, sodium and potasium and of course oxygen! :)
What are the three segments attached to the glycerol in a phospholipid?
A hydrophilic phosphate group and two hydrocarbon chains.
Why is oxygen not exchanged directly through the body surface in humans?
Humans are designed to use lungs for efficient oxygen transfer. The body surface (called skin or the epidermis) is designed more to keep harmful things out than to let oxygen in.
What appears directly below oxygen?
In the Periodic Table the element below oxygen is Sulphur.
What gas is needed to stay alive?
The gas you need to stay alive is Oxygen, you need oxygen to carry vital functions of body, when you inhale oxygen, its goes directly into the lungs and through alveolis, which are present in lungs oxygen get absorbed into blood which is then taken to heart and heart pumps the blood to each and every part and organ of the body, so like this your body works.
Can CO2 pass through the phospholipid bilayer?
oxygen
How do your cells get oxygen glucose and the raw materials that they need to respire?
Your cells get oxygen and glucose through protein channels located on their cell membrane the phospholipid bilayer surrounding a cell.
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)

Which materials will pass through the bilayer?
oxygen and carbon dioxide.
What particles can diffuse directly through the lipid bi-layer?
As the bilayer contains hydrophobic fatty acid tails, water-soluble molecules cannot diffuse directly through. However, lipid soluble molecules such as oxygen can diffuse directly through. Overall, for a molecule to be able to diffuse directly through it must be lipid-soluble, relatively small and non-polar.
What creates selective permebility of plasma membrane?
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
What molecule could move through a phospholipid membrane with the least difficulty?
h2o
Biological membranes are normally permeable?
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 are 3 molecules that pass through the lipid bilayer of the cell membrane?
oxygen, carbon dioxide, and water
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
What are plasma membranes permeable to?
