At Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na+ ions into the cell to the "uphill" transport of glucose into the cell. If the Nat concentration outside the cell ([Nat lout) is 161 mM and that inside the cell ([Na+]m) is 17.0 mM, and the cell potential is -50.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell. Assume the temperature is 37 °C. 10 62

- The following table shows experimental results of the glucose transport rate, mM/sec, following facilitated diffusion by glucose carrier proteins. (Recall: the starting conc. L represents glucose added to one side of the membrane; distilled water, omM of glucose was added to the other side of the membrane). The rate of glucose transport was 0.0031 mm/sec with 8mM of glucose (run number 4, highlighted); the rate decreased to 0.0017 mM/sec with 10mM of glucose (run 5, highlighted). Why was the rate of glucose transport slower when the concentration gradient was increased?

There are different versions of trust1, all of which lead to different levels of the behavior associated with this neuropeptide on male behavior. Give some examples where it would be a good idea to know a particular males genotype-that is, which of the trust1 genes he has. Give an example of when you think science has gone too far and this information should not be known.The movements of single motor-protein moleculescan be analyzed directly. Using polarized laser light, it ispossible to create interference patterns that exert a cen-trally directed force, ranging from zero at the center to afew piconewtons at the periphery (about 200 nm from thecenter). Individual molecules that enter the interferencepattern are rapidly pushed to the center, allowing them tobe captured and moved at the experimenter’s discretion.Using such “optical tweezers,” single kinesin mol-ecules can be positioned on a microtubule that is fixed toa coverslip. Although a single kinesin molecule cannotbe seen optically, it can be tagged with a silica bead andtracked indirectly by following the bead (Figure Q16–3A).In the absence of ATP, the kinesin molecule remains at thecenter of the interference pattern, but with ATP it movestoward the plus end of the microtubule. As kinesin movesalong the microtubule, it encounters the force of the inter-ference pattern, which simulates the load…
