Questions about Transport Proteins


PART 1: Objective Type

1._____________& 2.____________ What are the other terms used for Transport Proteins?

3. ____________ is a type of protein substrate transport that requires chemicals or cellular energy to mediate a specific solute.

4. ____________ is a type of protein substrate transport that passively carries biochemicals or molecular substances with the flow of the solvent across the cell membrane.

5. – 10. True or False:

______________ The substrate or the molecule, chemical, ion or substance to be transported must first bind at a binding site of the carrier or transport protein molecules to which it has a certain binding affinity with.

______________ Transport protein or Carrier molecules are generally firmly packed with polar regions on the outside.

______________ Polar regions from the outside of some specific molecules are utilized to intensify the solubility in water of most substances in the body that are not dissolved in water.

______________ Via Transport Proteins, the substrate will be discharged at the appropriate site and all steps are irreversible.

______________ After the substrate has associated with the transport protein molecule, it will temporarily alter its molecular and chemical structures.

______________ Transport proteins or Carrier molecules do not initiate the body regulation of the amount of specific biochemical processes.


PART 2: Analysis

Explain briefly how specific transport proteins recognize specific substances and the processes that occur or that are involved in the transportation of appropriate molecules.
