animals cannot produce enzymes to digest cellulose, yet many termite species consume cellulose from plant material as a main par
dimaraw [331]

Answer:

Termites have cellulose-digesting protists in their guts.

Explanation:

Termites are able to access nutrients contained in cellulose due to their mutualistic association with some cellulose-digesting protists such as <em>Trichonympha</em> and M<em>ixotricha</em>. The protists produce cellulase in addition to other glycolytic enzymes that work together to convert cellulose to malate.

The malate produced is further metabolized to produce CO_2, hydrogen, acetate and energy in the form of ATP.

The protists get sheltered in the termite's gut in return.
