Do Animal Have Enzymes: 7 Facts You Should Know

In this article, we came to know about do Animal have Enzymes or not. Animals are multicellular eukaryotic organisms. In an animal, many kind of metabolic reaction are simultaneously.

Animals performed different of activities and many metabolic activities which requires enzymes to carry out such task. Enzymes are mainly proteins that are synthesized inside body with the help of different types of amino acids. Enzymes are not actively participated in the reaction but it affects the rate of reaction.

Digestive enzymes are the most common enzymes used in the animals. Digestive enzymes like lipases, protease and amylase. Enzymes are either synthesized inside the animal body or will take as a dietary supplement with food.

Do Animal Cells have Enzymes?

All the enzymes have Enzymes which help to speed upt the all the biological reaction happening in the cells. Enzymes are the proteins which act as a biological catalyst ls for all the metabolic activities that going on in the cell.

Most of the enzymes are found in the lysosomes cell organelle found in the many animal cells. Lysosome is the spherical vesicles and membrane bound organelle that contains hydrolytic enzymes which can break down different types of biomolecules.

Many of the enzymes in animal cells are produced in the mitochondria. The mitochondrial DNA and ribosomes produces enzymes in the cytoplasm. Within mitochondria, DNA direct the ribosomes to produce proteins as enzymes mainly in the ATP production.

Do All Animals Have Enzymes?

All the animal cells have enzymes. Even all the living cells present on the earth have enzymes inside it. All the living organisms need enzymes for their growth and energy production which is necessities of life.

In most of enzymes, all the living cells produces enzymes on its own but enzymes are also present in products and food which are introduced mechanically.

Why Do Animals Need Enzymes?

Enzymes are the proteins that are required in many biochemical reactions to be occur in animal cells. They are essential for digestion, liver function and many more. Enzymes are involved in the growth, blood coagulation, healing, respiration, digestion, reproduction and may other kind of biological activities.

Enzymes help in singnal transduction. In the signal transduction, a chemical or physical signal is transmitted from one to other cell via a series of molecular and cellular responses. Most common enzymes for this purpose is protein kinase.

The main role of enzymes in animal cells for energy production. ATP (adenosine triphosphate) is the main storage form of energy. ATP is responsible to power up the biological activities. ATP are changed into suitable chemical forms by the enzymes. These enzymes are known as ATP synthases.

How Do Animals Produced Enzymes?

Enzymes are the polypeptide chains which are formed by joining of different amino acids present in the cell in the correct sequence. Every animal cells having DNA in it carry the information for formation of its specific proteins.

Enzymes are not synthesized in one step but as part of sequence of the enzymes required for each successive steps in the metabolic pathway. The composition of enzymes are determined by series of structural genes. With the help of these structural genes, molecules of messenger RNA carry transcribed instructions into the cell cytoplasm.

Where Are Enzymes Present In Animals?

There are millions of enzymes are believed to be present in the animal body. Each one is responsible for one specific function. Enzymes are divided into three general categories: digestive enzymes, metabolic enzymes, food enzymes.

The digestive enzymes are those enzymes which are produced within body to help for break down of food into its simple components for digestion. These are the enzymes found in stomach, Salivary gland, mouth and small intestine.

The metabolic enzymes are found throughout our entire animal body. Like in organs, bones ,blood and even in the cells which are responsible for their production. They function for the support of kidney, heart, lungs and brains.The food enzymes are present in the raw food. They’ll are served for the same function as of digestive enzymes.

List of enzymes found in animals

  • Lipases – the enzyme lipase is responsible for break down fatty acids into fats and oils. Lipases are made up by pancreas. If it is taking as a supplement then it will help to ease digestion process.
  • Amylase – the enzyme amylase splits starches and carbohydrates into simple sugars. The enzyme hydrolyse the internal glycosidic linkages in starch.
  • Maltase – the enzyme maltase breaks down maltose into glucose unit. It is present in saliva.
  • Cellulase – the enzyme cellulase responsible for digestion of structural carbohydrates into simple sugar. It is found in stomachs of fish with herbivore type of feeding and in those animal who primarily depend on plants for their food.
  • Phytase – the enzyme helps the digestion of phytic acid which is present in the grains, nuts and legumes.
  • Carbohydrases – the enzyme is helps in splitting of carbohydrates in several areas of digestive system. Most of the food we eat is of carbohydrates, this will be substrate for enzyme for its action.
  • Proteases- the enzyme split proteins molecules into amino acid. This enzyme helps to improve proteins digestibility.
  • Pectinase – it helps to break down indigestible pectin.
  • Xylanase – this enzyme helps in break down of fibers.

Role of Enzymes for Animals

  • Enzymes help to catalyse chemical processes which converts nutrients into energy and new tissue.
  • Enzymes help to split indiscriminating factors such as fibers, phytate which are found in the naturally in various food.
  • Enzymes helps to speed up the many chemical reactions in the animal body.
  • In the digestive tract of animals found different types of enzymes like proteases, carbohydrase and lipases that break down its specific substrate like proteins, carbohydrates and fats respectively, into simpler small substance which can easily absorbed into the bloodstream of animals.
  • Enzymes are not used up during the reaction this can be reused. Enzymes helps in specific function which are necessary for overall health of the body.
  • During cell division, the cell need to copy its DNA that helps in replication. Enzymes helps in this by unwinding of DNA coils.
  • The enzyme present in liver helps it to break down toxins in the body.
  • Enzymes helps in hormones production.
  • Enzymes play an important role in creating movement to make the muscles contract.
  • Enzymes helps in transportation of materials around the cell.
  • Enzymes are mandatory in the signal transduction.
  • Enzymes helps to reduce negative impact of animal production by minimising the animal waste production.


Enzymes are the necessities of animal cells. Without enzymes, animal cannot perform it’s basic functions. Enzymes are required in every metabolic activities like respiration, digestion, reproduction and circulation.
