Answer 1

Question 3

Which of the following is NOT an aspect of glycolysis?

c. It is irreversible

Three irreversible steps of glycolysis are:

1. Conversion of phosphoenolpyruvate to pyruvate(catalysed by pyruvate kinase in glycolysis).
2. Phosphorylation of glucose to glucose 6 phosphate.
3. Phosphorylation of fructose 6 phosphates to fructose 1,6 bisphosphate.

Question 9

Which of the following defines android obesity?

c.Storage of excess fat around the central part of the body

The main characteristics of android obesity are the excessive accumulation of fat over the abdominal part or the central part of the body

Question 12

A woman with a waist-to-hip ratio of 0.87 is considered to be:

c. at risk for health problems

According to Who, the recommended waist to hip ratio is lower than 0.85, thus we can say that the woman waist to hip ratio more than 0.87 is considered as they are more risk for getting health problems.

Question 15

What is the primary factor that characterizes the bulimia nervosa?

a. binge eating followed by purging

Bulimia nervosa is an eating disorder characterized by irresistible urge to take food followed by excessive preoccupation with the fear of gaining weight. The dreaded fear will lead to the typical compensatory behaviours of bulimia like self-induced vomiting, excessive use of laxatives and stimulants etc.

Question 16

Research in obese people seems to show that there is no increase in the risks for the strokes and hypertension provided that the excess body fat distributed around the:

c.Hips and thighs

The body distributes fat evenly can be better than it would be otherwise since concentration specifically around the lower abdomen, hips, buttocks, thighs.

Question 17

True or False: Body Mass Index (BMI) reflects the body composition

False

BMI does not take into account body composition so some people who are lean and carry a lot of muscle may have a BMI which does not necessarily reflect their health status.

Question 22

Which of the following can be used to fuel the brain and other activities in the absence of glucose from carbohydrate?

b.Ketones

Glycogen stores can be depleted such that they no longer supply glucose to the blood. In this case, glucose can be produced by protein catabolism and further catabolism of glucogenic amino acids. On the other hand, in the absence of carbohydrates in the diet, the brain switches to the use of ketone bodies as an energy source. Fatty acids, electrons and fat-soluble vitamins are not used directly in the brain as fuel because there is no efficient way of getting them there.

Question 23

During fasting, all of the following occur, except?

b. Glucose is used to build glycogen stores

During the fasting due to the hormonal action the hunger is suppressed and as well as the fat that is stored in the body is used for making energy for the functions of the body and as well as it decreases metabolism but it starts to metabolize your existing body fats so it helps burn that instead of just being stored in your body. During the fasting, the insulin levels fall as a compensatory mechanism the body will try to break down the glycogen stores to glucose. The liver is the sole proprietor of the breakdown of this glycogen back into the glucose that is to be released into the bloodstream. Glycogen breakdown occurs when the blood glucose levels are low and glucose is needed, which is usually caused by insufficient dietary carbohydrate intake. Maintaining adequate glucose levels in the blood is crucial for brain and muscle function.
