Answer #1

GLUT 1 is mainly the transporter of glucose but it also transport mannose and galactose. However the Km for glucose is much lower than the Km for mannose or galactose. This difference in Km means that GLUT 1 has different affinity for different substrate, lowest affinity for galactose and highest affinity for glucose.

So option D GLUT 1 transporter is correct

  • Using a technique called "Patch Clamping"

    Using a technique called "Patch Clamping", you can isolate a patch of membrane and then control the membrane potential across the patch of membrane (i.e., 1 change the potential difference across the membrane). You take a small patch of membrane, and change the membrane potential from the resting -70 mV to a lower potential difference of -15 mV and suddenly you detect a sudden influx of Nations across the patched membrane. Which of the following kinds of transporter is likely to be...

    Assume a mutation of the gene coding for the voltage-gated sodium channel resulted in channels that do not have the ball and chain part of the protein. Which of the following would you expect to see? a. A change in the ion selectivity of the channel of the mutated channels, allowing ions other than sodium to move through it. b. A change in the voltage sensitivity of the channel so that it does not open until more depolarized voltages. c....

    1. You lowered a patch-clamp onto a single ion channel. How would you identify what ion species it conducts? 2. You lowered a patch-clamp onto a single ion channel, which was created from RNA that you modified from RNA for a voltage-gated sodium channel gene. Name at least one feature of that ion channel you could identify that might tell you something useful about what the piece of ion channel you modified, might do.
