Which Of The Following Describes The Process Of Starch Digestion?

What happens to starch during digestion quizlet?

Carbohydrate starch is chemically digested by a small group of enzymes referred to as amalyses. Digest starch molecules. Starch consists of long chains of glucose molecules. Amylase breaks starch into 2-glucose units (disaccharides) called maltose.

Which of the following is responsible for the digestion of carbohydrates?

You begin to digest carbohydrates the minute the food hits your mouth. The saliva secreted from your salivary glands moistens food as it’s chewed. Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you’re eating.

What enzyme is responsible for carbohydrate digestion in the small intestine quizlet?

-In the small intestine, the amylase breaks the maltose into glucose. -An enzyme that works best at a pH between 6 and 7.4. This is why there is no carbohydrate digestion in the stomach, where the pH is between 1 and 3.5. You just studied 11 terms!

What is true carbohydrate absorption?

Almost all of the carbohydrates, except for dietary fiber and resistant starches, are efficiently digested and absorbed into the body. Some of the remaining indigestible carbohydrates are broken down by enzymes released by bacteria in the large intestine.

Where does starch digestion occur in the body?

Most carbohydrate digestion occurs in the small intestine, thanks to a suite of enzymes. Pancreatic amylase is secreted from the pancreas into the small intestine, and like salivary amylase, it breaks starch down to small oligosaccharides (containing 3 to 10 glucose molecules) and maltose.

Which chemical reaction takes place in the stomach?

Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

What happens to starch in the digestive system?

Digestion of carbohydrates is performed by several enzymes. Starch and glycogen are broken down into glucose by amylase and maltase.

What enzyme is used to digest proteins?

Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.

What happens to starch in the small intestine quizlet?

What happens to starch in the small intestine? Glycogen secreted by the pancreas hydrolyses starch into glucose, which is eventually transported to the liver. D. Amylase secreted by the pancreas digests starch to enable absorption by the villi.

What are the three enzymes involved in starch digestion?

Amylase, maltase, and lactase in the mouth digest carbohydrates.

What is the main site for digestion and absorption?

The small intestine is the site of most chemical digestion and almost all absorption. Chemical digestion breaks large food molecules down into their chemical building blocks, which can then be absorbed through the intestinal wall and into the general circulation.

What is the major monosaccharide found in the body?

The most nutritionally important and abundant monosaccharide is glucose, which is used as the major cell fuel in the human body and can be found unbound in body tissues and fluids. Glucose is the building block of several polysaccharides. Galactose and fructose are also used as cell fuel.

What is the process of absorption of carbohydrates?

The goal of carbohydrate digestion is to break down all disaccharides and complex carbohydrates into monosaccharides for absorption, although not all are completely absorbed in the small intestine (e.g., fiber). Digestion begins in the mouth with salivary amylase released during the process of chewing.

What is the first organ to receive carbohydrates absorbed from the intestine?

The first organ to receive carbohydrates from the small intestine is the liver. This is because of presence of hepatic portal vein which collects blood from around intestinal wall to liver.
