Membrane transport proteins – Compare and contrast transporters (aka carriers) and pumps. Include at least three features they share and at least three ways in which they differ.
Homework Answers
Pump:
-It shift small organic molecules or inorganic ions from one side
of the membrane to the other by CHANGING SHAPE.
-Pumps generate a membrane potential by creating an electrochemical
gradient across the membrane.
-Expenditure of energy.
-Works Against of according to concentration gradient.
Carrier:
-It form tiny HYDROPHILIC PORES across the membrane through which
such substances can pass by DIFFUSION.
-No generation of membrane potential.
-It follow passive pathway so no expenditure of energy.
-Movement of substances according to Concentration gradient.

Which of the following statements on membrane transport is NOT correct: A. To transport of solutes in the unfavorable direction across the membrane, pumps couple the process with either ATP hydrolysis, light absorption, electron transport, orother favorable transport process. B. Dissolved gases like O2, CO2, or NO simply diffuse across a membrane bilayer C. Hydrophilic molecules require assistance by membrane proteins to cross the membrane bilayer. D. The rate of transport facilitated by transporters is faster, but less selective for...

4. Glutamine transporters are proteins that, ironically enough, transport glutamine across a membrane. These transporters usually transport sodium along with them. Below is a depiction of the glutamine transport. The binding affinity for glutamine when it's open to the outside is 0.2 mM, while inside it spikes to 5 mM. Na Gln 1 mM 0.4mM Gln 0.7 mM Nat 0.5 mM Which direction would you hypothesize the sodium flow is going in? Why is this sodium transport necessary? When the...

Compare and contrast electron transport and ATP synthesis in mitochondria and chloroplasts. Start with the electron donor and end with the final electron acceptor. Detail the arrangement in the membrane and redox chemistry of the electron transporters, orientation and function of ATP synthase, membrane properties, etc., etc. How are these electron transport systems related to metabolic processes occurring in the mitochondria and chloroplasts?
