MCQ on transport across cell membrane (Active and Passive)
MCQ on Active and Passive Transport across the cell Membrane:
1. What is active transport?
(1) The movement of ions or molecules across a cell membrane from lower concentration to the higher concentration with the help of proteins or enzymes.
(2) The movement of ions or molecules across a cell membrane from higher concentration to the lower concentration.
(3) Both (1) and (2)
(4) None of these
Answer: 1
2. What is Passive Transport?
(1) The movement of ions or molecules across a cell membrane from lower concentration to the higher concentration with the help of proteins or enzymes.
(2) The movement of ions or molecules across a cell membrane from higher concentration to the lower concentration.
(3) Both (1) and (2)
(4) None of these
Answer: 2
