Summary Introduction
Introduction:
All living organisms are made up of cells and its products. Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. The cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. The protoplasm denotes all living materials that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).

Students have asked these similar questions
Na+ moves from high to low concentration, across the plasma membrane, through a protein channel that is permenantly open. Which statement is true about this process?
a. It does not require ATP
b. It is a form of active transport
c. Movement is against the concentration gradient of Na+
d. The channel probably allows many different molecules and ions to cross
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.
What variable(s) influence(s) whether a nonpolar molecule can move across a membrane by passive diffusion?
a. The structure of the phospholipids bilayer
b. The difference in concentration of the molecule across the membrane
c. The presence of transport proteins in the membrane
d. All of the choices are correct.
