To explain:
Digestion procedure in healthy individuals.
Introduction:
Starvation is the extreme case of malnutrition in which there is a severe deficiency in the caloric intake. In starvation, the amount of caloric intake is below than the normal amount which is required by the body to perform essential functions. Starvation has many forms like marasmus, kwashiorkor, anorexia, and bulimia.

Metabolic ketoacidosis is a common problem with diabetics, which is caused by which of the following?
Excessive oxidation of fatty acids, leading to an accumulation of ketone bodies in the blood.
Excessive oxidation of glucose, leading to an accumulation of ketone bodies in the blood.
Excessive oxidation of proteins, leading to an accumulation of ammonia in the blood.
Hyperglycemia.
Which of the following is TRUE regarding liver metabolism? Select three of the following:
The liver (hepatocytes) has hundreds of functions, such as producing glucose, ketones,
fatty acids, cholesterol, proteins, and bile for the rest of the body.
Hepatocytes have the GLUT2 antiporter, which allows for secondary active transport of
glucose into the cells.
Hepatocytes have glucokinase that continually makes glucose 6-phosphate, and it has a
lower Km than other hexokinases so it continuously metabolizes glucose when
concentrations are low.
Glucose 6-phosphate is the "transfer station" in the liver since it can be made my multiple
pathways and have multiple fates.
The liver converts amino acids to citric acid cycle intermediates or pyruvate for
gluconeogenesis.
The liver oxidizes fatty acids into glucose, which can be sent to other cells and used for
energy or converted into phospholipids and triacylglycerol.
Restriction of food intake leads to which of the following?
An increase in whole body energy expenditure
Reductions in resting energy expenditure due in part to reduction in body mass
An increase in the thermic effect of food due to lower energy intake
Reductions in activity energy expenditure due to increased activity costs associated with a smaller body size

- Fill in the blanks with a one word answer regarding Ketoacidosis. in the Ketoacidosis is a life threatening disease caused by a large buildup of bodies in the bloodstream. After prolonged starvation, the body starts breaking down liver because all of the are depleted and used up. This condition makes the body very (acidic, neutral or basic).arrow_forwardSymptoms of deficiencies Drag and drop each symptom of deficiency to the correct type of substance.

- Which of the following statements about the ketone bodies is/are TRUE? Produced during starvation and in diabetic patients Excess is transformed to acetone or hydroxybutyrate. Extreme amount of ketone bodies may cause ketosis in diabetics. Occurs during a high-lipid and low-protein diet.arrow_forwardWhich statement about steroids is TRUE? Cytochrome P450 monooxygenase introduces oxygen atoms into calcitriol. Cytochrome c oxidase requires cholesterol for full activity. All classes of steroid hormones have a different number of carbon atoms. Cholesterol is excreted from the organism only in the form of bile salts. All steroids are usually hydrophilic, so they can be transported without the help of lipoprotein particles.arrow_forwardWhich statements about absorption of vitamins or minerals are true? Select all that apply. Micronutrients may be in competition for absorption with each other. Vitamins and minerals are efficiently absorbed by the body between 85% and 99% of what is consumed. To be useful for cellular function, vitamins must remain in their original chemical structure. Calcium found in plant sources is more readily absorbed than from animal sources. Absorption of some vitamins and minerals can be influenced by what sort of foods are consumed within the same meal. Submit Request Answerarrow_forward
