B. New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
Explanation:
The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.
Cellular respiration is classified as an catabolic process in which an energy rich substance is broken down into a lesser one.
- Metabolic processes are usually divided into catabolic and anabolic processes.
- In catabolic step, energy is broken down.
- Cellular respiration is catabolic whereas photosynthesis is anabolic.
- The new compounds formed have lower energy bonds after respiration.

Answer;
Phospholipid.
Phospholipid forms a double layer as the primary structure of cell membranes.
Explanation;
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins.
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.
