Question 1 of 5
What is the preferred fuel for the cells lining the colon?
Correct Answer: A
Rationale: Short-chain fatty acids are the preferred fuel for the cells lining the colon. They provide energy and support gut health by serving as a fuel source for these cells. Long-chain fatty acids are not the preferred fuel for colon cells as they are harder to digest and absorb in this part of the digestive system. Amino acids are the building blocks of proteins and not the primary energy source for colon cells. Glucose is the main energy source for most cells in the body, but colon cells prefer short-chain fatty acids.
Question 2 of 5
The sugar to which all other sugars are converted during human metabolism is:
Correct Answer: C
Rationale: Glucose is the primary sugar used by the body for energy and is converted from other sugars during metabolism. Sucrose is a disaccharide composed of glucose and fructose, not the end product of sugar metabolism. Fructose is a simple sugar found in fruits but needs to be converted to glucose for cellular energy. Maltose is a disaccharide composed of two glucose units and is not the final product of sugar metabolism in humans.
Question 3 of 5
When counseling a teenager about fast food, a dental hygienist could correctly cite which of the following facts, with one exception. Which is the exception?
Correct Answer: D
Rationale: The correct answer is 'D'. Fast food is generally not deficient in protein since it often contains meat, a significant source of protein. On the other hand, fast food is known to lack essential nutrients like Vitamin A and certain minerals, as mentioned in choices 'A' and 'C'. Choice 'B' is also accurate as many fast food establishments have started offering healthier options such as salads due to customer demands. Therefore, all options are true except 'D', which makes it the exception.
Question 4 of 5
Which of the following saturated fats does not contain cholesterol?
Correct Answer: B
Rationale: The correct answer is B, Coconut oil. Coconut oil is a saturated fat derived from plants and does not contain cholesterol, unlike the other options. Butter (choice A) is an animal-derived saturated fat that contains cholesterol. Eggs (choice C) and fish (choice D) also contain cholesterol, making them incorrect choices. Therefore, coconut oil is the only option that is a saturated fat and does not contain cholesterol.
Question 5 of 5
Which cells in the islet of the pancreas are responsible for synthesizing insulin?
Correct Answer: B
Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.
