QuestionAnswer
Choose the list that presents the four stages of food processing in the order in which they naturally occur. ingestion → digestion → absorption → elimination
When digested, proteins are broken down into _____. amino acids
When digested, fats are broken down into _____. both glycerol and fatty acids
Starch is a type of _____. polysaccharide
Your small intestine can absorb ____ without their being further digested. frutose
Which of these enzymes begins the breakdown of starch? amylase
Starch can be broken down into the disaccharide known as _____. maltose
_____ is secreted by the _____ and acts to emulsify _____ in the _____. Bile ... liver ... fats ... small intestine
Different types of food are eaten by various groups of animals, but it is usually true that _____. cellulose digestion in ruminant mammals occurs before the ingested foods reach the small intestine
In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is fat in adipose tissue.
Certain nutrients are considered "essential" in the diets of some animals because these animals are not able to synthesize these nutrients.
To maintain adequate nutrition, animals require dietary access to certain amino acids. An amino acid that is referred to as "nonessential" would be best described as one that can be made by the animal's body from other substances
Which physiological process with the appropriate vitamin? production of white blood cells and vitamin K protection of skin from cancer and vitamin E normal vision and vitamin A synthesis of cell membranes and vitamin D blood clotting and vitamin C normal vision and vitamin A
The fat-soluble vitamins include calcium. iodine. vitamin B12. vitamin C. vitamin A. vitamin A.
Which pair correctly associates a biochemical process with the appropriate mineral associated with its use in animals? maintenance of bone and calcium
The most likely reason that some of the vitamins and minerals in this supplement are found at less than 100% is it is dangerous to overdose on fat-soluble vitamins such as A and K.
Fat digestion yields fatty acids and glycerol, whereas protein digestion yields amino acids; both digestive processes add a water molecule to break bonds (hydrolysis).
Ingested dietary substances must cross cell membranes to be used by the body, a process known as absorption.
An advantage of a complete digestive system over a gastrovascular cavity is that the complete system allows for specialized regions with specialized functions.
Earthworms, grasshoppers, and birds all have a crop
Because the foods eaten by animals are often composed largely of macromolecules, this requires the animals to have mechanisms for enzymatic hydrolysis.
For ingested foods, the first opportunity for enzymatic digestion occurs in the _____. mouth
In the digestive system, peristalsis is smooth muscle contractions that move food along the esophagus.
After ingestion by humans, the first category of macromolecules to be chemically digested by enzymes in the mouth is carbohydrates
Salivary amylase digests starches
Digestive secretions with a pH of 2 are characteristic of the stomache
Pepsin is a digestive enzyme that begins the hydrolysis of proteins in the stomach.
Upon activation by stomach acidity, the secretions of the parietal cells initiate the digestion of protein in the stomach.
The bile salts emulsify fats in the duodenum.
Complex nutrients are digested and then absorbed into the lymph or bloodstream as monomers
The absorption of fats differs from that of carbohydrates in that the most absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood.
For a nondiabetic person, the glucose concentration in this part of the vasculature varies more than in any other part. hepatic portal vessel
A significant contribution of intestinal bacteria to human nutrition is the benefit of bacterial production of vitamin K
Stomach cells are moderately well adapted to the acidity and protein-digesting activities in the stomach by having a thick, mucous secretion and active mitosis of epithelial cells.
The molar teeth of herbivorous mammals are especially effective at grinding
The adaptations suited to a carnivorous diet include bile salts
When the digestion and absorption of organic carbohydrates results in more energy-rich molecules than are immediately required by an animal, the excess is stored as glycogen in the liver and muscles.
A fasting animal whose energy needs exceed those provided in its diet draws on its stored resources in which order? liver glycogen, then muscle glycogen, then fat
Obesity in humans is most clearly linked to type 2 diabetes and cardiovascular disease.
Among mammals, it is generally true that the epiglottis prevents swallowed food from entering the trachea.
Because adult lampreys attach onto the surface of large fish for long periods of time to feed on body fluids, they can accomplish nutritional balance without need for a stomach
Many people have a tendency to gorge on rich, fatty foods. How could such a preference have evolved? In ancestral hunter-gatherer communities, individuals with a tendency to gorge on such foods when available would have had a selective advantage.
After surgical removal of an infected gallbladder, a person must be especially careful to restrict dietary intake of fats
If you were to jog 1 km a few hours after lunch, which stored fuel would you probably tap? muscle and liver glycogen
