What is the semipermeable membrane?
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
What are the three layers through which the filtrate must pass starting from inside the glomerular capillary through to the urinary space?
Glomerular Capillary Endothelium, Glomerular Basement Membrane, Visceral layer of Bowman's Capsule
The cell membrane allows some substance to pass through it and exclude others this is possible because the cell membrane is?
semi permeable
Which substance would most easily pass through a cell membrane?
Small, non-polar molecules like oxygen and carbon dioxide would most easily pass through a cell membrane.
How does the capillary help substanances pass through it?
Slow flow speed in the capillary increases the efficiency of diffusion. In addition, the thin wall of the capillary helps substances to pass through efficiently.
What is a holes in plasma membrane through which molecules pass across capillary wall?
The plasma membrane is made up of a lipid bilayer and some proteins. The transmembrane proteins are the structures which are involved in the transport of molecules in or through the cell.
State one possible reason a certain substance can not pass across a cell membrane?
The cell membrane is selectively permeable. Some substances like molecules are too big to pass through the membrane. The membrane allows passive transport of moleculesÊ by filtration, diffusion, or osmosis.
What is the term for living substance that has pores that allows water to pass through?
Biological membrane, cell membrane, fetal membranes: amnion, chorion,
What kind of membrane is where some substance can pass through and others can't?
semi-permeable membraneHope it helped :)
If a membrane was not permeable to sugars why would it probably also not be permeable to starch molecules?
If a membrane is permeable to a substance, it means that there are gaps/holes/pores in the membrane large enough for that substance to pass through. Starch molecules are bigger that sugar molecules. So if the membrane is not permeable to sugars, the gaps/holes/pores will not be big enough for starch molecules to pass through either.
Which substance could pass through the cell membrane readily?
Small molecules, such as water, oxygen, and carbon dioxide.
Would a polar substances such as sugars and amino acids pass through a cell membrane easily?
a substance such as sugar
