Document Summary
And we also looked at atp-driven pumps the p-type atp-driven pump (atpase) as an example of primary active transport. Today we"re also going to continue with primary active transport or. Atp-driven pumps & look at 2 additional types v-type atpases & f- type atpases. We"ll also look at how the different transporter proteins that we covered in the last lecture worked together in order to transport small molecules across a cell. In particular, we"re going to look at how a combination of transporters are used to transport glucose across the intestinal epithelial cells. Last lecture we covered the glucose symporter that passively transports glucose down its concentration gradient. We also covered the na-glucose symporter an example of secondary active transporter. And we also looked at na-k pump which is an example of an atp- driven pump or transport atpase that uses the energy from the hydrolysis of atp to transport both na & k against their electrochemical gradients.
