(c) active transport
Explanation:
Active transport uses energy (ATP) to pump molecules against a concentration gradient. Cells undergoing active transport bear abundant mitochondria to provide ATP, needed to power active transport. So, the production of ATP is blocked or decreased and active transport is blocked or slow down.
