The $Na^+/K^+$ pump is an example of ..........

Consider the following statements and choose the correct answer:
$I.$ Carrier proteins are needed by both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chains.
$II.$ Different types of proteins present in the membrane play a major role in both active as well as passive transport.
$III.$ The carrier proteins needed by facilitated and active transport are specific.
$IV.$ There is no need of energy to pump molecules against a concentration gradient in active transport.
$V.$ Transport rate reaches a saturation point when all the active proteins are used.

$A$: Simple diffusion is a passive transport process.
$R$: Passive transport does not require energy.

Which of the following types of transport are included in passive transport?

Which process is responsible for short distance movement?

Which of the following processes shows uphill transport?
