Question

Why is active transport important?

Answer 1

Active transport:

1. Active transport is the cellular transport that utilizes chemical energy to move substances across a biological membrane.
2. This transport is conducted when molecules are transported from a region of lower concentration to a region of higher concentration.
3. This mode of transport requires a transport protein to coordinate the crossing of substances across the membrane.
4. It is crucial for cell survival and rapid nutrient absorption by the cells.
5. It is key for the excretion of toxins and signal transduction.
6. It is also involved in the transport of ions, nutrients, vitamins, and osmolytes in higher organisms.
