Question
Chapter 7, Problem 16TYK
Summary Introduction
Introduction: The energy-dependent process where the molecules are moved from a region of lower concentration to a region of higher concentration against their concentration gradient is called as active transport.

Which of these transport pathways require ATP? Select all that apply.
A. Sodium-potassium pump
B. Glucose transporter
C. Osmotic diffusion
D. Calcium pump
Among the membrane transporters, the channels require energy and therefore are involved in active transport. *
D. Disagree, because channels are not proteins and therefore are not involved in active tranport.
A. Agree, because channels are associated with H+-ATPase.
B. Disagree, because the pumps are the ones involved in active transport.
C. Agree, because channels are proteins involved in active transport.
