BIOXI11: TRANSPORT IN PLANTS
336285
Which of the following affects the transport molecules when facilitated diffusion is involved?
1 Solubility of molecule in lipids
2 Concentration gradient
3 Presence of carrier protein
4 All of them
Explanation:
In Facilitated diffusion, the rate of diffusion is affected by the solubility of molecules in lipids, concentration gradient, molecular size of the molecules, etc. Availibility of carrier molecules also affects the rate of transport in facilitated diffusion.
BIOXI11: TRANSPORT IN PLANTS
336286
Find the correct statement from the following
1 Simple diffusion is highly selective in nature
2 Transport saturation occurs in diffusion as well as in facilitated diffusion after a lapse of time
3 Transport protein is mobile in active transport
4 Protein inhibitor binds with the side chain of proteins for active transport while facilitated diffusion performing transport proteins remain unaffected
Explanation:
Pumps are proteins that use energy to carry substances across the cell membrane.

Identify the type of transport when two type of molecules move together in the same direction.
1 Symport
2 Antiport
3 Uniport
4 All of these
Explanation:
When carrier proteins allow movement of two types of molecules together, it is termed as cotransport. It can be further divided into two types; symport and antiport. In symport, two types of molecules are transported in the same direction.

Identify the incorrect statement
1 Facilitated diffusion is not very specific.
2 Porins allow the passage of molecule of size up to small protein.
3 Water channel made up of eight different type of aquaporins.
