Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.
With the Whig Party in ruins, Lincoln joined the new Republican Partyâformed largely in opposition to slaveryâs extension into the territoriesâin 1858 and ran for the Senate again that year (he had campaigned unsuccessfully for the seat in 1855 as well).
In 1860, Lincoln secured the Republican Party presidential nomination as a moderate from a swing state. Though he gained very little support in the slaveholding states of the South, he swept the North and was elected president in 1860.
