What is the relationship between the ATP-ADP cycle and catabolic and anabolic reactions?

A) Energy released from catabolic reactions is used to recharge ADP back to ATP. Then the energy needed for anabolic reactions is released by breaking ATP down to ADP.
B) Catabolic reactions require energy, which is provided by anabolic reactions. ADP is recharged to ATP by energy from anabolic reactions.
C) Energy released from catabolic reactions is used to break ATP down to ADP. Then the energy needed for anabolic reactions is released by to recharging ADP back to ATP.
D) Energy released from anabolic reactions is used to recharge ADP back to ATP. Then the energy needed for catabolic reactions is released by breaking ATP down to ADP.

You experiment by unwrapping some of the strange yellow plants and planting half of them alone in pots of soil and half in pots with other plants from your yard. You water and fertilize both sets of pots, but after a few weeks you find that the yellow plants that were potted alone have died, while those potted with other plants are thriving. What term would you use to describe the strange yellow plants?
