Final answer:
Non-spontaneous transport is known as active transport, which requires ATP to move substances against their concentration gradient, unlike passive transport which occurs spontaneously without energy expenditure.
Step-by-step explanation:
The type of transport that is non-spontaneous is active transport. Active transport requires the cell to use energy, typically in the form of ATP (adenosine triphosphate), to move substances against their concentration gradient. This is in contrast to passive transport, which does not require energy and occurs when substances move along their concentration gradient from an area of higher concentration to an area of lower concentration.
For example, the maintenance of sodium and potassium ion concentrations across a cell membrane is achieved through active transport using the sodium-potassium pump. In this process, sodium ions are pumped out of the cell and potassium ions are pumped into the cell, both against their concentration gradients, illustrating that the cells expend energy for this transport mechanism.
