Which of the following transport induces conformational changes in proteins?

Choose the correct sentences for diffusion:
$(1)$ In diffusion,molecules move in a random fashion.
$(2)$ Diffusion rates are affected by the gradient of concentration.
$(3)$ Diffusion is a slow process and is dependent on a 'living system'.
$(4)$ Movement by diffusion is passive.

Uphill transport is a type of

$A-$ In an antiport,both molecules move in opposite directions.
$R -$ In symport,only one molecule crosses the membrane in the same direction.

Choose the correct option for $P, Q$ and $R$.

Property	Simple Diffusion	Facilitated Transport	Active Transport
Transport Saturation	$P$	Yes	Yes
Uphill Transport	No	No	$Q$
Requirement of Energy	No	$R$	Yes

$P, Q$ and $R$ respectively are:

$S -$ Statement: Energy is consumed during active transport.
$R -$ Reason: This transport occurs against the concentration gradient of the substances.
