An investigator wants to understand whether a newly found membrane protein is involved in membrane transport of a certain particle. Which investigation will determine whether the new membrane protein is a channel protein involved in membrane transport?
Understand the Problem
The question is asking which experimental investigation can demonstrate whether a newly discovered membrane protein functions as a channel protein for particle transport across the cell membrane. This involves evaluating the methods listed to determine their relevance to membrane transport processes.
Answer
Add more proteins and measure particle movement rate.
The investigation to add more of the proteins to the plasma membrane and measure the rate of particle movement will determine if the protein is a channel protein involved in membrane transport.
Answer for screen readers
The investigation to add more of the proteins to the plasma membrane and measure the rate of particle movement will determine if the protein is a channel protein involved in membrane transport.
More Information
Channel proteins facilitate the passive movement of particles via concentration gradients. By increasing the amount of the protein, its involvement in transport can be assessed by changes in particle movement rates.
Tips
Confusing active transport with passive membrane transport can lead to improper testing designs.
