Step by step
Solved in 2 steps
- Distinguish between passive and active transport mechanisms across cellmembranes.1) You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described? 2) What are peripheral membrane proteins?The three fundamental classes of proteins involved in transport across membranes are: i) channelsii) pumpsiii) exchangers For each class, describe its essential features, explain how transport is accomplished and name at least one representative example.
