Question

the two major categories of membrane transport are □ transport that requires no energy expenditure and □ transport
need help? review these concept resources.

Explanation:

In cell biology, membrane transport is divided into two main types. Passive transport does not require energy (it relies on concentration gradients, like diffusion or facilitated diffusion). Active transport requires energy (usually ATP) to move substances against their concentration gradient. So the first blank is "passive" and the second is "active".

Answer:

First blank: passive; Second blank: active
