Question

read the article and use the information to answer the following questions. active transport in active transport, molecules are moved across the cell membrane with the help of proteins. what does it mean if a molecule is moved against the concentration gradient?

Explanation:

Moving a molecule against the concentration gradient means moving it from an area of lower concentration to an area of higher concentration. This process requires energy and is often facilitated by transport - proteins, as in active transport.

Answer:

It means the molecule is moving from an area of lower concentration to an area of higher concentration, and energy is required for this movement, usually with the help of transport - proteins (active transport).
