Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is an active transport mechanism?
A
Osmosis
B
Facilitated diffusion
C
Filtration
D
Pinocytosis
Explanation: 

Detailed explanation-1: -Once inside the cell, the protein is digested into its constituent amino acids, which are reabsorbed through the basolateral membrane into the interstitial fluid. Because pinocytosis requires energy, it is considered a form of active transport.

Detailed explanation-2: -Active transport: moving against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.

Detailed explanation-3: -Phagocytosis, pinocytosis, and exocytosis are all examples of active transport. Active transport is a type of transport that uses energy. During phagocytosis, cells use their membrane to take in large molecules from the external environment.

Detailed explanation-4: -Some of the best examples of active transport include: Phagocytosis of bacteria by Macrophages. Movement of Ca2+ ions out of cardiac muscle cells. Transportation of amino acids across the intestinal lining in the human gut.
