Which of the following statements about cell membrane transport is correct?
a) The process of simple diffusion is specific and consumes energy.
b) Facilitated diffusion is mediated by transmembrane proteins and is not specific.
c) Active transport is a process of substance transport in favor of a concentration gradient and without energy expenditure.
d) The hydrolysis of ATP provides energy for proteins in the plasma membrane to perform active transport of sodium ions to the extracellular medium and potassium ions to the intracellular medium.
e) Osmosis is the transport of water against a concentration gradient, moving from the medium with less solute to the medium with more solute.
