An ATP molecule attaches to the protein and is broken down into ADP and an inorganic phosphate.
The energy released from this chemical bond causes the protein to undergo a "conformational change" (it flips or opens). active transport primary and secondary
Found in almost every human cell, this pump is the quintessential example of primary active transport. It moves of the cell and two potassium ions ( K+cap K raised to the positive power An ATP molecule attaches to the protein and
Once upon a time, in a bustling city called Cellville, there lived two hardworking pumps named Percy and Paisley. They lived in the cell membrane, the thin layer of tissue that separated the cell from the outside world. It moves of the cell and two potassium
The most famous example of primary active transport is the . It is essential for nerve impulses and muscle contractions.
Think of primary active transport as a pump filling a water tower. Secondary active transport is like using the pressure of that falling water to turn a mill wheel. How it Works:
