Understand the general functions and properties of biological membranes. - Answer Biological membranes enclose the cell, defines it's boundaries and maintains differences between the cytosol and extracellular environments. It is selectively permeable, self-assembles in water, and can form mycel or bilayer (cone shape vs cylindrical shape), it is composed of phospholipids. What types of molecules are membranes made up of? - Answer The plasma membrane consists of lipids and proteins (5...

Why can a sodium ion not pass through a potassium leak channel? - Answer The sodium ion cannot interact correctly with the oxygen atoms of the selectivity filter of the potassium leak channel. What is a difference between active transport and passive transport? - Answer Passive transport goes from high concentration to low concentration while active transport goes from low concentration to high concentration What is a property of the membrane spanning region of a membrane protein? - ...

Which of the following ate true concerning monomeric GTPases such as Ran, Rab and Sar1? a. arresting locks them in a dimeric GTP bound configuration b. they are converted from the inactive form to the active form by the dephosphoylation of the a subunit of GPCR c. they contain a, s and D subunits that associate together when activated d. the conversion from the inactive the GDP bound to the active GTP bound form is accomplished through appropriate GEFs e. they are inhibited through the a...

How do proteins get moved between the nucleus and the cytosol? - Answer By nuclear pore complex. Small molecules can move across the pores via gated transport. Large molecules are shuttled across via active transport. Nuclear import receptors bind to nuclear signal sequence. RAN-GTP provides energy for active transport, but smaller protein will freely diffuse. What are nuclear pore complexes? - Answer Proteins that actively transport proteins out of the nucleus. What is a nuclear imp...
