Kidney-pumping out glucose
|
|
|
Root hair cells-pumping in mineral ions
|
Detailed explanation-1: -The uptake of glucose in the intestine of the human body and also the uptake of minerals or ions into the root hair cells of the plants are some of the examples of active transport.
Detailed explanation-2: -Detailed Solution. Correct answer is Sodium and potassium pumps. The Sodium-potassium pump present on the cell membrane is a classic example of active transport.
Detailed explanation-3: -One of the greatest instances of active transport is the transfer of calcium ions out of heart muscle cells. Cells secrete proteins such as enzymes, antibodies, and a variety of other peptide hormones.
Detailed explanation-4: -What are the examples of active and passive transport? Phagocytosis, pinocytosis, and sodium-potassium pump are examples of active transport while diffusion, facilitated diffusion and osmosis are examples of passive transport.
