NEET Biology question
Not in NEET syllabus
Consider the following statements and choose the correct answer.
I. Carrier proteins are needed by both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chains. II. Different types of proteins present in the membrane play a major role in both active as well as passive transport. III. The carrier proteins needed by facilitated diffusion and active transport are specific. IV. There is no need for energy to pump a molecule against a concentration gradient in active transport. V. Transport rate reaches a saturation point when all the active protein pumps are being used.
Solution
Statements I, II, III and V are all correct — carrier proteins are needed by (and are inhibitor-sensitive in) both processes, membrane proteins mediate both active and passive transport, carriers are substrate-specific, and transport saturates once all
