What is it called when ingested dietary substances must cross cell membranes to be used by the body?
The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.
What vitamins are fat soluble quizlet?
What are all the fat soluble vitamins? Vitamins A, D, E and K.
What are vitamins ADE and K?
Vitamins A, D, E, and K are all fat-soluble vitamins. Water-soluble vitamins are different. These vitamins dissolve in water. When you eat foods that have water-soluble vitamins, the vitamins are not stored in your body.
What does pepsin do in the stomach?
An enzyme made in the stomach that breaks down proteins in food during digestion. Stomach acid changes a protein called pepsinogen into pepsin.
What cells secrete the acidic components of stomach juices?
Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
Which of the following is an advantage of a complete digestive system over a Gastrovascular cavity?
There are obvious advantages of such a system over a gastrovascular cavity, among them the fact that food moves in one direction through the tubular system, which can be divided into a series of distinct sections, each specialized for a different function.
How does the absorption of fats differ from carbohydrates?
b) Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine.
Which vitamins are water soluble quizlet?
What are the water soluble vitamins? Thiamin, Riboflavin, Niacin, Folate, Vitamin B12, Vitamin B6, Biotin, Vitamin C, and Pantothenic acid.
What does fat soluble mean quizlet?
Definition of Fat Soluble Vitamins. Vitamins that can be stored in the fatty tissues of the body. Generally needed in smaller amounts. Toxic if taken in large amounts. Only $35.99/year.
Where are fat soluble vitamins stored in the body quizlet?
They are stored in the liver and in adipose (fat tissue). They are released as they are needed and since they are needed in such small amounts, the intake can be irregular.
How are vitamin ADE and K absorbed by the body?
The fat soluble vitamins A, D, E and K are absorbed from the intestinal lumen using the same mechanisms used for absorption of other lipids. In short, they are incorporated into mixed micelles with other lipids and bile acids in the lumen of the small intestine and enter the enterocyte largely by diffusion.
Is vitamin K water or fat soluble?
"Vitamin K," the generic name for a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone, is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement [1].
Which vitamins and minerals are fat soluble?
Fat-soluble vitamins include vitamins A, D, E, and K. Minerals. These include calcium, copper, iron, magnesium, phosphorus, potassium, selenium, and zinc.
Which digestive enzyme hydrolyzes protein in the stomach quizlet?
-Pepsinogen was secreted by chief cells in the stomach. -Pepsin hydrolyzes proteins into peptides.
Which enzyme initiates protein digestion?
Pepsin initiates protein digestion in stomach.
Which of the following is protein digesting enzyme?
Pepsin converts proteins and peptones into proteins and (peptides). Polypeptide chain proteins are hydrolyzed by Pepsin and protein digestion is initiated. Pepsin is also an enzyme that digests protein.
