How can you tell if glucose starch water and iodine passes through the cell membrane?

place starch solution inside the partially permeable membrane and than partially submerge it a beaker filled with distilled water. after some time, take the tubing out and test the water inside the beaker for starch by adding iodine solution. if the tubing is permeable to starch, the starch would have diffused into the water in the beaker and test positive for starch and turn dark blue. if not, then the water in the beaker would test negative for starch and remain a yellowish brown solution.

What part of blood transport glucose?
Blood transports glucose through our nerve system and also through the red blood cells.Glucose is transported to the cells by a uni porter. It passes through the erythrocytes membrane (red cell membrane) and as soon as it enters, it is turned into a chemical and/or a source for energy.
Can Hydrogen peroxide pass through a cell membrane?
yes, H2O2 passes through cell membrane through passive transport.
Where does oxygen go after it passes through the the cell membrane?
The Mitochondria
What is it called when sugar passes through an animal cell?
glucose (sugar) can diffuse through cell membranes
What passes through a cells membrane?
stuff liek water and such that the cell needs to survive. the membrane is selective about what it allows in and out. bad stuff hardly ever makes it in.
Why is it not a good idea to store iodine in plastic bag?
The Iodine permeates (passes through) the plastic.

What is the channel in the nuclear membrane through which the RNA passes?
The nuclear PORE membrane
What is the substances that passes through a cell?
cell membrane

What controls what passes in and out of cells?
Through something called "Selective permeability"
The process by which simple sugar passes through a membrane is called?
diffusion
What is a type of diffusion in which water passes through a cell membrane?
Osmosis
What is a osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
What happens to the blood as it passes through the liver?
when the blood passes through the liver it carries the CARBON DIOXIDE produced by the liver during cellular respiration
Is a membrane made of proteins?
Cell membranes consist of a bilayer phospholipid (hydrophobic tails and hydrophyllic heads), cholesterol, glycolipids (grow off phospholipids) and glycoproteins (grow off proteins), intrinsic Proteins (passes through both layers), extrinsic proteins (passes through only one layer). Finally, a channel protein/ transport protein/carrier protein, allow big molecules (glucose) to pass through the cell membrane.
