In .......... both molecules cross the membrane in the same direction.

What is meant by influx and efflux?

Which of the following criteria does not pertain to facilitated transport?

What are the factors affecting the rate of diffusion?

Identify the following process and choose the correct option.

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.
