What is the importance of glucose?

Series of reactions that remove energy from glucose by splitting it into two or three carbon molecules (pyruvates) is known as Glycolysis.

Glucose is the main energy source for cellular metabolism.  Human beings  derive energy from three classes of fuel molecules, namely carbohydrates, lipids, and proteins. The potential chemical energy is transformed into other forms such as thermal or kinetic.

Glucose is absorbed by stomach and small intestines absorb and then released into the bloodstream. Once they reach the bloodstream, then glucose can be used immediately for energy or stored, to be used afterwards. Human bodies require insulin to use or store glucose for energy.

how are fungi organized to stay alive?​

Answers

Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus

HOPE THIS HELPED <3

Answer/Explanation:

Somewhat like animals, Fungi need oxygen and eat dead organisms in order to survive. A fungus may look like a plant, however it gets energy from living of dead plants and sometimes other fungi. Fungi need a moist area to live with plenty of oxygen making rotted out trees a perfect place to grow.

Fungi are eukaryotes and have a complex cellular organization. As the fellow answerer above said, it has mitochondria and cell membranes that are artistically arranged. Unlike plants, they do not have chloroplasts nor chlorophyll.
