Question 1

Which of the following substances can be metabolized for ATP production?

Accepted Answer

Glucose is a carbohydrate that can be broken down through cellular respiration to produce ATP. Vitamin C, iron, and insulin are not sources of energy and cannot be metabolized for ATP production.

Question 2

Most people who suffer from anorexia nervosa

Accepted Answer

One of the physical symptoms of anorexia nervosa is the loss of body fat, which can result in shrunken breasts and buttocks. The other options are incorrect; not all individuals with anorexia die, positive self-esteem is not a common feature of the disorder, and individuals with anorexia typically have a fear of gaining weight rather than a desire to do so.

Question 3

People who exercise regularly can reduce their risk of

Accepted Answer

Regular exercise can help strengthen bones and reduce the risk of osteoporosis. Exercise is not directly linked to reducing the risk of anemia, goiter or cretinism.

Question 4

Which of the following activities is generally classified as aerobic?

Accepted Answer

Cycling is a form of cardiovascular exercise, which requires continuous oxygen consumption and large muscle group movements over an extended period of time. It is considered aerobic because it strengthens the heart and lungs, improves endurance, and promotes overall health and fitness. The other options (stretching, performing squats, and line dancing) are not necessarily considered aerobic as they do not require the same level of sustained energy expenditure and oxygen consumption.

Question 5

____ can be metabolized for ATP production.

Accepted Answer

Protein can be metabolized to produce ATP through the process of cellular respiration. Niacin (D) is important for energy metabolism but is not a source of ATP by itself. Vitamin D (A) and iron (B) are not directly involved in ATP production.

Question 6

Which of the following statements is true?

Accepted Answer

Aerobic exercise is characterized by rhythmic, sustained contractions of large muscle groups. Examples of aerobic exercise include running, cycling, and swimming.

Option B is incorrect because walking, bowling and playing golf are not considered as vigorous-intensity physical activities but rather they are moderate-intensity activities.

Option C is incorrect because even low-intensity physical activities like household chores, gardening, and walking can be considered as physical activities if they increase your heart rate and breathing rate.

Option D is incorrect because if you cannot have a conversation while exercising, you are most likely working your large muscle groups at a vigorous-intensity level, not a moderate-intensity level.

Question 7

By performing exercise regularly,people can reduce their risk of

Accepted Answer

Regular exercise has been shown to reduce the risk of cardiovascular disease by improving heart health, maintaining healthy blood pressure and cholesterol levels, and reducing the risk of obesity and type 2 diabetes. It does not have an effect on the risk of type 1 diabetes, pernicious anemia, or spina bifida.

Question 8

Including exercise in your daily routine can reduce your risk of

Accepted Answer

Studies have shown that regular physical activity can reduce the risk of colon cancer. Exercise helps in maintaining a healthy digestion system and can reduce the growth of polyps in the colon. Type 1 diabetes, anemia, and ulcerative colitis are not necessarily prevented through exercise.

Question 9

Michelle's weekly exercise program includes stair stepping,static stretching,cycling,and push-ups.Which of these activities is generally classified as a flexibility exercise?

Accepted Answer

Static stretching is the type of exercise that improves flexibility by holding a stretch in a stationary position for a set period of time. Stair stepping, cycling, and push-ups are considered cardio or strength training exercises.

Question 10

Under anaerobic conditions,muscle cells convert pyruvate to

Accepted Answer

Under anaerobic conditions, when oxygen supply to muscle cells is limited, pyruvate is converted to lactic acid through the process of anaerobic glycolysis. This helps to regenerate NAD+ which is required for continuation of glycolysis to produce ATP.

Question 11

_____ is the primary source of direct energy for cells.

Accepted Answer

ATP (Adenosine triphosphate) is the primary source of direct energy for cells, as it powers almost all cellular activities. Glucose, fat, and proteins serve as sources of energy but need to be converted into ATP via cellular respiration.

Question 12

Which of the following activities is generally classified as aerobic?

Accepted Answer

Stair stepping involves movement that increases heart rate and breathing, making it an aerobic activity. A, B, and D are not consistently aerobic activities. While doing household chores or bowling can increase heart rate and breathing in some cases, it is not guaranteed and therefore cannot be classified as aerobic. Stretching does not involve the required level of movement to be classified as aerobic.

Question 13

Which of the following activities is generally classified as aerobic?

Accepted Answer

Running is an activity that requires sustained, continuous movement of large muscle groups and increases heart rate and respiration. This is characteristic of aerobic exercise, which improves cardiovascular health by increasing the body's capacity to use oxygen. Static stretching, yoga, and bowling are not aerobic because they typically do not elevate heart rate or respiration for sustained periods of time.

Question 14

Most people who suffer from anorexia nervosa

Accepted Answer

Anorexia nervosa is an eating disorder that is often associated with emotional disturbances such as feelings of low self-worth, anxiety, and depression. While individuals with anorexia nervosa may have high levels of perfectionism and drive, these characteristics are often coupled with deep feelings of insecurity and inadequacy. Additionally, individuals with anorexia nervosa oftentimes experience amenorrhea (loss of menstrual cycles) as a result of their low body weight, rather than having multiple periods per month. It is important to note that anorexia nervosa is a serious mental illness and can have fatal consequences if left untreated, but with appropriate care and support, many individuals are able to achieve full recovery.

Question 15

Which of the following substances can be metabolized for ATP production?

Accepted Answer

Fat can be metabolized through a process called beta-oxidation to produce ATP. Insulin, iron, and B vitamins are not directly metabolized for ATP production.

Question 16

During a dental examination,the dentist notices that the enamel on the back sides of Andrew's teeth has eroded,and the some of the teeth are decaying.Based on this information,the dentist suspects that Andrew

Accepted Answer

The erosion of enamel and tooth decay on the back sides of the teeth are classic signs of bulimia, a disorder characterized by frequent binge eating followed by purging through vomiting or other means. The stomach acid from repeated vomiting can damage the enamel on teeth and lead to decay. Therefore, option B is the best choice. A vitamin D deficiency disorder or excessive intake of dietary fiber are unlikely to cause these dental issues. While irregular brushing can contribute to tooth decay, it would not be limited to the back sides of the teeth.

Question 17

People who exercise regularly can reduce their risk of

Accepted Answer

Regular exercise has been shown to reduce the risk of breast cancer, as well as other types of cancer, by up to 20-30%. Exercise helps regulate hormone levels, reduces inflammation, and strengthens the immune system. Regular exercise has not been linked to a reduced risk of goiter, anemia, or type 1 diabetes.

Question 18

Michelle's weekly exercise program includes stair stepping,static stretching,cycling,and push-ups.Which of these activities is generally classified as a strength (resistance)exercise?

Accepted Answer

Push-ups are generally classified as a strength (resistance) exercise as they involve pushing against the weight of the body, which helps to build and tone muscles. Stair stepping and cycling are cardiovascular exercises, while static stretching is a flexibility exercise.

Question 19

People who exercise regularly can reduce their risk of

Accepted Answer

Regular exercise has been shown to improve insulin sensitivity and reduce the risk of developing type 2 diabetes. Exercise does not have a significant impact on the risk of developing cretinism or megaloblastic anemia. Spina bifida is a congenital condition and cannot be prevented through exercise.

Question 20

Which of the following statements is true?

Accepted Answer

Weight lifting and other strength exercises have been shown to increase bone mass by stimulating the bones to become stronger and denser.

Note: B is false as television watching is classified as a sedentary activity, not a moderate-intensity physical activity. C is false as a well-planned exercise program should include both cardiovascular exercise and strength training, but the frequency and duration may vary based on individual goals and needs. D is false as household chores may provide some physical activity but have not been specifically linked to a reduced risk of type 1 diabetes.
