Which of the following statement best describes how absorbed dietary lipids are transported?
Which of the following statement best describes how absorbed dietary lipids are transported? Absorbed lipids are transported within lipoproteins called chylomicrons from the small intestines to the liver. Cholesterol is an essential dietary nutrient because it cannot be made in the body.
Which statement is true about digestion?
Digestion is a form of catabolic activity because it involves the breaking down of food into smaller sizes that can be absorbed as nutrients by the body while releasing energy through the process. The statement about digestion which is true is that, gastric juice helps to process food into chyme.
Which of the following statements about lipid digestion is false?
Bile is a salt which combines the large fat droplets, which means that bile salt break large fat droplets into smaller fat droplets. Hence, the given statement that is Bile is the digestive enzyme that act to break down fats is false because it is not an enzyme but all the process is carried out by the Bile salt.
What do sodium fatty acids and vitamin A have in common quizlet?
Both are major electrolytes in the body. Both are involved in nerve transmission.
What are the 5 types of lipoproteins?
Plasma lipoproteins are separated by hydrated density; electrophretic mobility; size; and their relative content of cholesterol, triglycerides, and protein into five major classes: chylomicrons, very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-
Which lipoprotein is the main carrier of cholesterol?
LDL (low-density lipoprotein), sometimes called “bad” cholesterol, makes up most of your body’s cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke.
What are the 2 types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
Where does digestion start?
Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.
Where are enterocytes found?
Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes.
What enzyme digests fat?
Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on.
How many different forms of lipids are commonly found in food?
The three main types of lipids are triacylglycerols (also known as triglycerides), phospholipids, and sterols. 1) Triglycerides make up more than 95 percent of lipids in the diet and are commonly found in fried foods, butter, milk, cheese, and some meats.
Where does fat get absorbed in digestive system?
Small intestine The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
What is bile production?
Introduction. Bile is a physiological aqueous solution produced and secreted by the liver. It consists mainly of bile salts, phospholipids, cholesterol, conjugated bilirubin, electrolytes, and water . Bile travels through the liver in a series of ducts, eventually exiting through the common hepatic duct.
What does vitamin D absorb?
We need vitamin D to help the body absorb calcium and phosphate from our diet. These minerals are important for healthy bones, teeth and muscles. A lack of vitamin D, known as vitamin D deficiency, can cause bones to become soft and weak, which can lead to bone deformities.
What are the 3 macronutrients What are 3 examples of each?
The “big 3” macronutrients (macros) are fats, carbohydrates and protein. When eaten in the right ratios, these three macronutrients can improve your weight, health and overall physical well-being.
