Cellulose and glycogen are both homopolymers of glucose units. humans cannot digest cellulose but can break down glycogen into individual glucose units. which type of enzyme is lacking in humans that would allow them to break down cellulose? hint: look at the name of the enzyme to see the type of bond they are involved in breaking down through catalysis.

the lacking in human is called Cellulase which is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis and bring about the decomposition of cellulose and of some related polysaccharides.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
