Is digestion of food a chemical change. A chemical process may be a process that involves the chemical transformation of a chemical
substance into a different. Whereas, a physician may be a process that doesn’t involve any chemical transformations.

Digestion of food may be a chemical process because the massive macromolecules are weakened into simpler molecules by the enzymes present within the stomach and therefore the intestines. it’s a chemical process because it involves various chemical reactions.
Hence the solution may be a chemical process.

A chemical process may be a change during which one chemical substance is claimed to possess transformed into one or more other chemical substances.

These changes occur through chemical reactions, during which the molecules and therefore the ions rearrange themselves to make different structures and thus have different properties.

They are mostly irreversible reactions but some changes are said to be reversible.
A phase change may be a change during which the changes affect the shape of a chemical substance but don’t change its chemical composition.

These changes are wont to separate mixtures into their constituent compound but it doesn’t separate compounds into chemical elements or simpler compounds.

A phase change may be a change that’s subjected to the physical properties of a substance.
Now, keeping the above definitions in mind allow us to answer the question.

For a chemical process, a few things got to be kept in mind.

* Colour change
* Formation of a precipitate
* Formation of a gas or gas bubbles
* Odor or taste change
* Volume change
* Production of sunshine and lots of such changes.

For a phase change, a few things got to be kept in mind.

* Change in size and volume
* Change in density and mass
* Change in pressure
* Change in temperature
* Change in color
* Change in texture and adaptability

Digestion steps

There are six activities involved during digestion. these are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.

The mouth and esophagus

Digestion begins within the mouth. The teeth grind the food. Saliva moistens it for easy swallowing. Saliva is made of a special enzyme, which breaks down carbohydrates into sugars. Once swallowed, the esophagus contracts and massages the food into the stomach.

The stomach

The passage for the food is a sphincter or small muscle ring to the stomach. Here it’s mixed with gastric juices. The stomach may be a muscular bag, and it churns the food to assist break it down mechanically also as chemically.

A second sphincter squeezes the food into the primary part of the tiny intestine, called the duodenum.

The small intestine

Once within the duodenum, the food is mixed with more digestive enzymes from the pancreas and bile from the liver. The food then squeezes into the lower parts of the tiny intestine, called the jejunum, and therefore the ileum.

The ileum absorbs food by using many finger-like projections called villi, which are in its lining. These are connected to a network of capillaries. This is often how nutrients pass into the bloodstream.


The pancreas is one of the most important glands within the physical body. Also as digestive juices, it secretes a hormone called insulin. Insulin helps to manage the quantity of sugar in the blood. Diabetes may be a condition caused by problems with insulin production.


The liver has several different roles within the body, including:

• breaks down fats with bile stored in the gall bladder
• processing proteins and carbohydrates
• filtering and processing impurities, drugs, and toxins
• forming of glucose for short-term energy needs from other compounds like lactate and amino acids.

The large intestine

Once all the nutrients are absorbed, the waste is moved into the massive intestine or bowel. Water is removed and therefore the waste (feces) is stored within the rectum. It is pushed out of the body via the anus.

Common problems within the gastrointestinal system

Some common problems include:

• colitis – inflammation of the bowel
• diverticulitis – inflammation of pouches lining the tiny intestine
• gastroenteritis – This causes vomiting and diarrhea
heartburn – when the contents of the stomach copy into the esophagus
• ulcer – a hole within the mucosa lining the stomach or duodenum.

Digestive juices

In the stomach, there is a mixing of food and liquid with digestive juices. Then the food starts to empty from the stomach, This is called chyme and is emptied into your intestine.
Small intestine.

The small intestine mix food with digestive juices which are released by the pancreas and liver and pushes the mixture forward for further digestion. The walls of the small intestine absorb the mixture of water, and the digested nutrients into your bloodstream.

As peristalsis continues, the by-products of the digestive process go to the large intestine.
Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your alimentary canal. 

The massive intestine absorbs water and changes the waste from a liquid into the stool. Peristalsis channels the stool into your rectum.

The lower part of your intestine, the rectum, stores stool until it is pushed out of your anus when you visit the restroom.

How does my gastrointestinal system break food into small parts my body can use?
As food moves through your alimentary canal, your digestive organs break the food into smaller parts using:

• motion, like chewing, squeezing, and mixing
• digestive juices, stomach acid, bile, and enzymes

Glands in your stomach make stomach acid and enzymes that break down food.
Pancreas. Your pancreas makes a digestive fluid that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive fluid to the tiny intestine through small tubes called ducts.

Liver. Your liver makes a digestive fluid called bile that helps digest fats and a few vitamins. Bile ducts carry bile from your liver to your gallbladder for storage or for the tiny intestine to be used.
Gallbladder. Your gallbladder stores bile between meals. 

Small intestine. Your intestine makes digestive fluid, which mixes with bile and digestive juice to finish the breakdown of proteins, carbohydrates, and fats. Bacteria in your intestine make a number of the enzymes you would like to digest carbohydrates.

Your intestine moves water from your bloodstream into your alimentary canal to assist break down food. Your intestine also absorbs water with other nutrients.

Large intestine. In your intestine, more water moves from your alimentary canal into your bloodstream. Bacteria in your intestine help break down remaining nutrients and make vitamin K.

What happens to the digested food?

The small intestine absorbs most of the nutrients in your food, and your cardiovascular system passes them on to other parts of your body to store or use.

Your blood carries simple sugars, amino acids, glycerol, and a few vitamins and salts to the liver. It then stores, processes, and takes nutrients to the remainder of your body if needed.

The lymph system is a mesh of vessels. It takes white blood cells and lymph all over your body to fight infection, and absorbs fatty acids and vitamins.
Your body uses sugars, amino acids, fatty acids, and glycerol to create substances you would like for energy, growth, and cell repair.

How does my body control the digestive process?

Your hormones and nerves work together to assist control the digestive process. Signals flow within your alimentary canal and back and forth from your alimentary canal to your brain.

Cells lining your stomach and little intestine make and release hormones that control how your gastrointestinal system works. These hormones tell your body when to form digestive juices and send signals to your brain that you simply are hungry or full.


Your brain and spinal cord control digestive functions. for instance, once you see or smell food, your brain sends a sign that causes your salivary glands to “make your mouth water” to organize you to eat.

You also have an enteric systema nervosum (ENS)—nerves within the walls of your alimentary canal. When the alimentary canal is stretched, the nerves of your ENS release many various substances that speed up or delay the movement of food and therefore the production of digestive juices. The nerves send signals to regulate the actions of your gut muscles to contract and relax to push food through your intestines.

Digestion with restriction enzymes

Restriction digestion is a process in which DNA is cut at specific sites, dictated by the encompassing DNA sequence. Enzymes recognize and bind specific DNA sequences and cleave at specific nucleotides either within the popularity sequence or outside of the popularity sequence.

Restriction digestion may result in the production of blunt ends or sticky ends. The procedure allows fragments of DNA to be pieced together like building blocks via ligation.

The products of the digestion are separated by molecule length (based on the charge of DNA molecules) during a polymer gel to which an electrical field has been applied.

You find typical restriction digestion reactions in the DNA template, the restriction endonuclease of choice, a buffer, and also BSA protein.

The reaction is incubated at a special temperature needed for maximum activity of the restriction endonuclease and destroyed by heat.
