The gradient tells us how steep a line is, therefore the bigger the gradient the steeper the line is. A positive gradient is a straight line which slopes up to the right. A negative gradient is a ...
The gradient of a line is calculated by dividing the difference in the \(y\)-coordinates by the difference in the \(x\)-coordinates. This may be referred to as the change in \(y\) divided by the ...
In place of such an intermediate, Mitchell proposed a proton gradient across a membrane: the proton motive force (Mitchell 1961). It works much like a hydroelectric dam. The energy released by the ...
