Which type of macromolecule contain high energy bonds and is used for long term energy storage

Lipids.

Explanation:

Lipids are compounds with varied molecular structure, presenting several organic functions: energy reserve (energy source for hibernating animals), thermal insulator (mammals), in addition to collaborating in the composition of the plasma membrane of cells (phospholipids).

Lipids are molecules that contain high-energy bonds and are used for long-term energy storage. They can be classified into oils (unsaturated substances) and fats (saturated substances), which are found in foods of both vegetable and animal origin, as well as in fruits (avocado and coconut), soy, meat, milk and its derivatives and also in the egg yolk.

In general, all living things are capable of synthesizing lipids, however, some classes can only be synthesized by vegetables, as is the case with fat-soluble vitamins and essential fatty acids.
