ive Transport 4/10 square square is any type of transport through a cell membrane that requires energy. Check It A Tour

## Step 1
The problem is asking for the type of transport that requires energy to move substances across a cell membrane. This is a fundamental concept in cell biology, specifically in the study of cellular transport mechanisms.

## Step 2
There are two main types of transport mechanisms that cells use to move substances across their membranes: passive transport and active transport.

## Step 3
Passive transport does not require energy and moves substances from an area of higher concentration to an area of lower concentration. This process is driven by the concentration gradient.

## Step 4
On the other hand, active transport requires energy, usually in the form of ATP (adenosine triphosphate), to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration.

## Step 5
The question specifically asks for the type of transport that requires energy, which is active transport.
