Carrier proteins
They are two different proteins, like the difference between a train and a robot. The difference between one protein and the other is the amino acid sequence that comprises that protein and the molecular bonding that determines its shape. Shape determines function in a protein. If it loses its shape it can't do its job. The shape of insulin and hemoglobin is different so insulin binds with glucose and hemoglobin binds with oxygen.
the carrier protein changes shape to release the molecule inside of a cell
The shape of a protein allows it to perform its particular job.
because the shape of a protein allows it to perform its particular job
The protein that changes shape when calcium ion (Ca2+) binds to it, is the troponin. It is a regulatory protein that is a component of the thin filament.

the rate of the reaction can be increased or decreased
because every receptor has specific shape on it, which binds with specific molecule.
it binds with several signaling molecules as it has shape that is complementary to signaling molecules.
A protein cannot perform its biological function, if it is not in the correct shape. Sometimes an incorrectly folded protein will become a very dangerous toxin called a prion.
Once translated, proteins are dispersed throughout the cellular environment. This section covers the transport of a protein into a specific organelle--the mitochondria.
Actin Changes ShapeApexMyosin binds to ActinAPEX
Carrier Proteins. Some don't require ATP (Facillitated transport) and some do require ATP (Active transport) to change shape.
