Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
|
|
Substances are moving rapidly across the cell membrane
|
|
|
ATP is being rapidly consumed near the cellular membrane
|
|
|
substance are moving from high to low concentrations
|
|
|
substances are moving through channels in the cell membrane
|
Explanation:
Detailed explanation-1: -The difference between passive transport and active transport is that the active transport requires energy, and moves substances against their respective concentration gradient, whereas passive transport requires no cellular energy and moves substances in the direction of their respective concentration gradient.
Detailed explanation-2: -Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Detailed explanation-3: -The answer is A) A substance goes from an area of low concentration to an area of high concentration, and this requires energy.
