Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

Answer:
To produce energy from available sugar.
Explanation:
The biochemical reaction can still occur if the blood sugar level is lower than the normal range because energy is needed by the body for its activities. The biochemical reactions helps in producing energy in the form of ATP that is needed by the body for its different activities. The lower level of sugar in the blood does not fulfil the needs of body but provides some energy for it so that's why the body produces energy from available sugar present in the body.
