When enzymes in your body digest your food, what type of biomacromolecule is at work?

proteins

Explanation: enzymes are specialized proteins.during digestion,they act as biological catalyst as they help to break down ingested food particles into forms that can be absorbed.Most enzymes are secreted in an inactive form.eg pepsinogen which is converted to pepsin,it's active form.

Digestive enzymes can act on #proteins---they are called protease

#Carbonhydrate---they are called carbonhydrases

#Fats---they are called lipases.

Enzymes are specific to the type of reaction they catalyst.

Other function of proteins in the living cells include

# contractile proteins in the muscles helps in motion of organisms

#receptor proteins for hormones and cell signalling

#proteins found in the membrane of cells.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
