What is the most direct consequence if a protein loses its specific three-dimensional form?

It would spontaneously transform into a different class of macromolecule, such as a lipid or a carbohydrate.

It would lose its ability to perform its specific function within the cell.

It would break apart into individual atoms and disperse throughout the cytoplasm.

It would begin to work more efficiently because its structure is more flexible.

Scientists discover two different proteins that carry out two very different functions in an organism. What can they most likely conclude about these two proteins?

They have different physical structures.

They are made of different types of atoms.

One must be a liquid and the other a solid.

They are located in the same part of the cell.

That proteins are made of hard, rigid materials similar to metal.

That a protein's specific shape is precisely suited for its specific task.

That cells can build many different things using only one type of protein.

That proteins are simple in design and easy for the cell to construct.

A protein's function is random and unrelated to its structure.

A protein's structure is a direct result of the function it performs.

A protein's structure is critical because it dictates the specific job the protein can do.

All proteins have the same basic structure, but they perform different functions.

Its structure is flexible, allowing it to bind to any particle.

Its structure is very simple, preventing unwanted reactions.

Its shape fits the foreign particle precisely, like a lock and key.

Its shape allows it to absorb energy from the virus.
