NEET Biology MCQ on Active transport with Answers by Expert Teacher. Every Objective Questions is Important and Common for NEET-UG Exam.
1) The transport of molecules against the concentration gradient is called as ———-.
A) Active transport B) Passive transport C) Diffusion D) Osmosis.
Answer: Answer is A, when molecules pass against the concentration gradients and uphill process called as active transport.
2) Which of the following process is uphill process?
A) Passive transport B) Diffusion C) Osmosis D) Active transport
Answer: Answer is D, remaining are downhill process.
3) Which of the following are characteristics of active transport?
A) Uphill process B) Require energy C) Against electrochemical gradient D) All of these.
Answer: Answer is D,all are the characteristics of active transport because active transport from low concentration to high concentration, against the electrochemical gradient.
4) Which of the following ions can be transported by active transport?
A) Glucose B) O2 C) N2 D) CO2
Answer: Answer is A, glucose is large polar molecule transported by active transport.
5) Active transport is ——.
A) Spontaneous B) Non spontaneous C) Both A and B D) None of these.
Answer: Answer is B, because gibbs free energy is also positive in active transport.
6) The two molecules can be transported at a time is called as—-.
A) Primary active transport B) Secondary active transport C) Co-transport D) Both B and C.
Answer: Answer is D, secondary active transport also called as co transport because two molecules are transported at a time.
7) Which of the following are types of secondary active transport?
A) Uniport B) Symport C) Antiport D) Both B and C.
Answer: Answer is D, in symport and antiport two molecules are transported at a time.
8) Energy source used in active transport are:
A) ATP B) Light C) PEP D) All of these.
Answer: Answer is D, all the sources are used in active transport.
9) Which of the following transporters used in primary active transport?
A) P- type pump B) Channel C) GLUT 1 D) Aquaporin
Answer: Answer is A, P- type pump used in primary active transport.
10) Reverse osmosis is ———- mechanism.
A) Active transport B) Passive transport C) Diffusion D) Osmosis.
Answer: Answer is A, because reverse osmosis needs energy.
