Question

Which of these is/are not a property of facilitated transport?
(a) Requires special membrane proteins
(b) Highly selective
(c) Uphill transport
(d) Requires ATP energy

• A. a and b only
• B. c and d only
• C. a and c only
• D. b and c only
• E. b and d only

Answer 1

The correct option is B c and d only

• Facilitated transport or diffusion or passive-mediated transport can be defined as the process of spontaneous passive transport of molecules or ions across a cell membrane through the specific transmembrane integral proteins.
  
• It does not require the ATP molecules and is the diffusion is downhill.
• So, the correct answer is 'c and d only'.
