Secondary active transport protein link the transport of an ion downward its gradient with the transport of another particle against its gradient, whereas primary active carrier proteins move both components in the opposite direction of their respective gradients.
<h3>Which proteins are essential for active transport?</h3>
Instead of channel proteins, carrier proteins are used in active transport. Since these carrier proteins require ATP to change shape, they differ from those seen in facilitated diffusion.
<h3>Why do proteins play a part in active transport?</h3>
- Specialized carrier proteins are needed for active transport, and cellular energy must be used.
- When a chemical's phospholipid bilayer is impermeable to it or when there is a concentration gradient, carrier proteins allow chemicals to pass through the membrane.
<h3>What kinds of proteins are carriers?</h3>
The carrier proteins can be categorized as being driven by ATP, electrochemical potential, or light, depending on the source of energy.

Marshes give off saturated soil: "Marshes, also known as wetlands, are frequently inundated (flooded) with water. Plants found in marshes such as the common cattail, lily pads, and duckweed are adapted to the saturated soil conditions. Animals commonly seen in a marsh are otters and muskrats. There are many different types of marshes including coastal, inland, fresh water, salt water, riparian, and more. Marshes get their water from surface water (rain/runoff) and ground water." (Gundersen Envision,p.1)
