Question
Active transport is the net (overall) movement of particles from an area of high concentration to an area of lower concentration.Question 13Answera.Trueb.False
Solution
The statement is false.
Here's a step-by-step explanation:
-
Active transport is a process that moves ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
-
This process is against the concentration gradient, meaning it moves substances from an area of lower concentration to an area of higher concentration. This is the opposite of what the statement says.
-
Active transport is necessary for many physiological processes, such as the absorption of glucose in the intestines and the reabsorption of ions in the kidneys.
-
It's called "active" transport because it requires the cell to expend energy, usually in the form of ATP (adenosine triphosphate), to move the substances against the concentration gradient.
So, the correct answer is b. False. Active transport is the net movement of particles from an area of low concentration to an area of higher concentration, not the other way around.
