Question

Which is the best example of active transport?

Answer 1

Active Transport:

1. Active transport is the movement of molecules across the cell membrane with the assistance of cellular energy.
2. This type of transfer occurs for cellular energy from a lower to a greater concentration location.
3. It occurs in human cells in order to obtain the energy required for diverse tasks.
4. Active transport is employed by cells to accumulate chemicals required by cell-like amino acids and glucose from a lower concentration location to a higher concentration region.
5. The transport powered by adenosine triphosphate (ATP) is known as the main active transport, whereas the transport powered by an electrochemical gradient is known as secondary transport.

Examples:

1. Cells use active transport to store essential chemicals like glucose and amino acids.
2. One of the greatest instances of active transport is the transfer of calcium ions out of heart muscle cells.
3. Cells secrete proteins such as enzymes, antibodies, and a variety of other peptide hormones.
4. Amino acid transportation occurs between the intestinal lining of the human gut.
