Question

Moving from high to low concentration requires the use of energy to transport substances. This is called active transport and uses ________.

1) ATP
2) ADP
3) AMP
4) GTP

Answer 1

Active transport requires energy to move substances against the concentration gradient, which is provided by adenosine triphosphate (ATP).

Step-by-step explanation:

Moving from high to low concentration without using energy is known as passive transport. However, when substances need to be moved from an area of low concentration to an area of high concentration, cells must use an energy-consuming process known as active transport. This process works against the concentration gradient and requires energy. The energy used in active transport typically comes in the form of adenosine triphosphate (ATP), which is the cell's primary energy-carrying molecule. Therefore, the correct answer to which substance is used in
