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? .

Add more of the proteins to the plasma membrane and measure the rate of the particle movement.

Explanation:

A membrane protein is a protein molecule that is attached to or associated with the membrane of a cell or organelle. Membrane proteins can be grouped into two groups based on the way they associate with the membrane.:

A channel protein is an embedded protein found the cell membrane which provides a hydrophilic passageway for water and small, polar ions. They have a size which excludes all but the specific molecules which move from an area of high concentration to an area with a lower concentration.

To determine if the new membrane protein is a channel protein involved in membrane transport, an experiment could be made by adding more of the proteins to the plasma membrane and measure the rate of the particle movement. If the channel is involved, then the rate will be faster because there are more channels that make the movement faster.

it is very expensive

explanation:

cells spend most of their time in interphase
