How is facilitated diffusion different from diffusion?

Which of the following statements is correct?
$(I)$ Rapid uptake of ions into the free space is a passive process.
$(II)$ Apoplast is important for passive processes.
$(III)$ Metabolic energy is required in passive processes.
$(IV)$ In the apoplast,passive processes occur through ion channels.

Match the following columns correctly:

Column-$I$	Column-$II$
$(a)$ Passive transport	$(p)$ Movement from higher concentration to lower concentration, no energy required
$(b)$ Active transport	$(q)$ Movement along the concentration gradient, requiring carrier proteins
$(c)$ Facilitated diffusion	$(r)$ Movement against the concentration gradient, requiring energy
$(d)$ Osmosis	$(s)$ Diffusion of solvent molecules across a semi-permeable membrane

Which of the following processes shows uphill transport?

In which transport,carrier molecule is necessary but energy is not utilised?

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.
