What else can I help you with?
What contains an enzyme that starts the chemical digestion of food?
saliva is the substance in the mouth that contains enzymes to help with digestion before the food is swallowed.
What are two basic ways that cells can digest a substance?
Cells can digest substances through intracellular digestion, where enzymes break down molecules inside the cell's cytoplasm, or through extracellular digestion, where enzymes are secreted outside the cell to break down larger substances before they are absorbed.
Does chemical digestion occur before mechanical digestion?
Both get started at about the same time. As the teeth are grinding up the food, enzymes in the saliva are breaking down starch.
Why doesn't the small intestine contain the acid chyme?
The duodenum is the main site for digestion in the small intestine. Here, more enzymes are added to the chyme, some of which come from the intestinal wall and others from the pancreas. The pancreas is one of the major glands of the body, and has two functions: releasing digestive enzymes into the gut, and releasing hormones into the blood. Pancreatic juice also contains sodium bicarbonate, which neutralizes the acid chyme arriving in the duodenum, and provides an alkaline environment for optimum functioning of pancreatic and intestinal enzymes. These enzymes include proteases to continue protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Enzymes in the intestinal juice generally start off the later stages of digestion.
What glandular secretions involved in digestion would be most likely released initially as inactive precursors?
The pancreatic enzymes involved in digestion, such as trypsinogen and chymotrypsinogen, are released initially as inactive precursors. This is to prevent damage to the pancreas and other tissues before they reach the small intestine, where they are activated by other enzymes.
Why is the stomach the first site of chemical digestion in the frog?
The stomach is the first site of chemical digestion in frogs because it contains gastric juices that are rich in enzymes and acids, specifically pepsin and hydrochloric acid. These substances help break down proteins into smaller peptides, facilitating further digestion. Additionally, the stomach's muscular contractions mix the food with these digestive secretions, enhancing the breakdown of nutrients before they move to the intestines for further digestion and absorption.
Structures that produce enzymes that digest food in the mouth?
The primary structure responsible for producing enzymes that digest food in the mouth is the salivary glands. These glands secrete saliva, which contains the enzyme amylase, responsible for breaking down starches into simpler sugars. Additionally, the enzyme lipase, found in smaller amounts, helps in the digestion of fats. Together, these enzymes initiate the digestive process before food moves to the stomach.
How is mammalian digestion more efficient than the type of digestion seen in bacteria?
it is more efficient because we are able to break down the food particles to increase surface area exposed to enzymes before hydrolysis
Is unienzyme tablet and carmozyme syrup the same?
No, Unienzyme tablet and Carmozyme syrup are not the same. Unienzyme tablet contains digestive enzymes and is usually taken to aid digestion. Carmozyme syrup, on the other hand, is a liver tonic that supports liver function and aids in digestion. It is important to consult a healthcare professional before taking any medication or supplement.
Why is saliva an enzyme?
Saliva contains enzymes like amylase that help break down carbohydrates in food into simpler sugars that can be absorbed by the body. This process begins the digestion of carbohydrates in the mouth before they reach the stomach for further processing.
What is a eukaryotic hetertroph with external digestion?
A eukaryotic heterotroph with external digestion is a fungus. Fungi obtain nutrients by secreting enzymes externally to break down organic matter, such as dead plants or animals, before absorbing the resulting nutrients. Examples of fungi include mushrooms, yeasts, and molds.
Do dwarf hamsters have a split down there belly?
yes. The Stomach of a hamster is split up into two unique sections. The first stomach contains beneficial bacteria or microbes that help with digestion by fermenting the food the hamster ate. These bacteria make it so the hamster can eat fibrous foods like grasses. The second section is a stomach similar to humans. It contains acids and enzymes that break down the food for a few hours before it is passed into the intestines for further digestion. A hamster uses a type of ruminant digestive system.
