What is electrogenic pump ? Name main electrogenic pump in animal cells and bacteria, fungi and plants.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Electrogenic Pump:**
An electrogenic pump is a type of transport protein that moves ions across a cell membrane, creating a difference in charge (voltage) across the membrane. This process is essential for various cellular functions, including the generation of membrane potential and the transport of nutrients and waste products.

2. **Functionality of Electrogenic Pumps:**
Electrogenic pumps utilize energy, often derived from ATP (adenosine triphosphate), to transport ions against their concentration gradient. This means they move ions from an area of lower concentration to an area of higher concentration, which is essential for maintaining the electrochemical gradients necessary for cellular processes.
