Active Transport

Both Passive and Active Transport
|
Detailed explanation-1: -In this biological process, energy is not required for transporting the molecules, as the biochemicals move from a region of higher concentration to a region of lower concentration. All particles which are easily soluble are transported through passive transport.
Detailed explanation-2: -Passive transport requires no energy input, as compounds are able to move freely across the membrane based only on a favourable concentration gradient (Figure 1.11).
Detailed explanation-3: -Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.
Detailed explanation-4: -The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.
Detailed explanation-5: -Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
