kHumans produce the majority of the cholesterol essential for cell membranes for vitamin D and steroid hormone production. What would you anticipate to happen if a person's diet has an abnormally high level of cholesterol? Justify your answer.
Step by step
Solved in 2 steps
- For people who want to lose weight, one of the most popular diets is a protein-rich, carbohydrate, and fat-free diet. One risk of this diet is the formation of kidney stones. Explain whyHigh blood-cholesterol levels are dangerous because of their correlation with atherosclerosis and consequent heart attacks and strokes. Is it possible to eliminate all cholesterol from the bloodstream by having a diet that includes no cholesterol? Is it desirable to have no cholesterol at all in your body? Explain your answer.Humans produce the majority of the cholesterol essential for cell membranes for vitamin D and steroid hormone production. What would you anticipate to happen if a person's diet has an abnormally high level of cholesterol? Justify your answer.
- A new energy drink in stores contains no sugar, carbs or fat. It does, however, contain relatively high concentrations of B-vitamins (B-3, B-5, B-6, and B-12) which our digestive system does not break down. If our useable energy (ATP) is supplied by cellular respiration, where would the energy this products claims to provide come from?In contrast to water-soluble vitamins, which must be part of our daily diet, fat-soluble vitamins can be stored in the body in amounts sufficient for many months. Suggest an explanation for this difference.After a meal that contains carbohydrates, blood glucose levels usually rise gradually as carbohydrates are digested and the resulting monosaccharides are absorbed into the bloodstream. Suppose you run a test on a human with no lactase production. You would provide a dose (e.g., 25 grams) of lactose and measure changes in blood glucose levels over the next three hours. Predict how blood glucose levels would change from fasting to three hours. Justify your response using the results from the above simulation.
- All of the following statements about glucose are true except: Glucose is metabolized in the cytoplasm of prokaryotic organisms. On a low-carb diet, keto acids from glucogenic amino acids will be used to synthesize glucose. Glucose is metabolized in the mitochondria of mature red blood cells. Under non-starvation conditions, the brain relies exclusively on glucose as its fuel source.When comparing two multivitamins in the store, you see that one has 500% of the daily value for a particular vitamin, while the other has 100% of the daily value for that vitamin. Is the one with 500% of the daily value necessarily better for your health? Explain your answer.Which of the following statements regarding glucose is NOT true? a.)Glucose is a monosaccharide sugar b.)Glucose can be metabolized by both aerobic and anaerobic metabolism c.)The normal blood glucose concentration is 4-7 mmol/l d.)A high blood glucose concentration is called hypoglycemia
- Lactose intolerance is caused by reduced production of the enzyme lactase. A variety of digestive system problems, such as celiac disease and Crohn’s disease) can also lower the production of lactase. If an individual produces low levels of the enzyme lactase, explain why they might be able to tolerate eating dairy products that contain lower levels of lactose (e.g., hard cheeses, feta cheese, and cottage cheese), but will not be able to tolerate foods with high levels of lactose (e.g., milk).Glycerol cannot be used for a cell's energy needs. is this statement true or false?Select the best answer or answers from the choices given: Transamination is a chemical process by which (a) protein is synthesized, (b) an amine group is transferred from an amino acid to a keto acid, (c) an amine group is split from the amino acid, (d) amino acids are broken down for energy.
