Question

If a cell was exposed to a poison that blocked the cell's ability to manufacture ATP, which of the following effect would it have on the cell membrane's transport process?

• A. There will be no active transport
• B. There will be no change in the membrane's transport process
• C. There will be increased active transport
• D. There will be no diffusion

Answer 1

The correct option is A There will be no active transport

ATP is the source energy required for the active transportation of the molecules against the concentration gradient. When the cell is exposed to the poison which blocks the production of ATP by the cell, there will be no active transport due to lack of ATP.

Thus, the correct answer is option A.
