QUIZ Answers
*************************************
1) Which organ typically burns the most energy per day in an average adult?
a. Heart
b. Liver
c. Brain
d. Lungs
*************
Answer: C the brain consumes approximately 21 % of daily calories
*************
2) Which exercise type is characterized by working past the threshold for sustainable oxygen consumption?
a. Isometric exercise
b. Aerobic exercise
c. Anaerobic exercise
d. Plyometric exercise
*************
Answer: C
*************
3) Doing core exercises (abdominal exercises) is vital for reducing belly fat.
a. True
b. False
*************
Answer: B, while very important to overall orthopedic health and balance, a strong core won't help a lot with reducing belly fat as core muscles are relatively small, and don't produce large amounts of force (being stabalizer muscles, not power muscles) and thus don't require extensive energy.
*************
4) What is the name for the metabolic state in the body characterized by a calorie deficit and an increase in the burning of lean tissue mass?
a. Anabolism
b. Homeostasis
c. Hyperplasia
d. Catabolism
*************
Answer: D
*************
5) This Micronutrient is responsible for muscle contraction, nerve transmission and bone formation. It is also used when PH levels become overly acidic.
a. Iodine
b. Calcium
c. Potassium
d. Phosphorous
*************
Answer: B, Only Calcium meets all of these requirements.
*************
6) The best single measurement to use when calculating whether someone is at a healthy weight for their age, sex, and height is?
a. Body Mass Index (BMI)
b. Body Fat Percent
c. Basal Metabolic Rate (BMR)
d. Waist to Hip Ratio
*************
Answer: B, While the best way to analyze health would include all of these, if you must single out a statistic, BF% is the best overall measurement and in most cases will allow you to make generic assumptions about that individual.
*************
7) To avoid an exercise related plateau, you should change your exercise times every:
a. 6 to 8 weeks
b. 2 to 3 weeks
c. 10 to 12 weeks
d. About every 4 to 6 months
*************
Answer: A, Human voluntary muscle movements take approximately 6 to 8 weeks to develop a memory for an activity. This increases performance and efficiency of caloric expenditure and thus reduces calorie burn.
*************
8) A ketogenic diet is a diet where:
a. The percentage of macronutrients from carbohydrates is raised and fat is lowered significantly
b. The percentage of macronutrients from fats and proteins is raised and carbohydrates are lowered significantly.
c. The food eaten is lower than the amount needed for maintaining weight, and water intake is increased.
d. The diet is a natural diet consisting of foods only found in nature, and little or no processing is allowed.
*************
Answer: B
*************
9-12) Place the letter of the definition that corresponds to the correct hormone.
9) Insulin
10) Testosterone
11) Cortisol
12) Growth Hormone (GH)
a) This hormone is secreted by the anterior pituitary gland. During sleep it stimulates amino acid uptake and protein synthesis in muscle cells.
b) This hormone is secreted by the pancreas in response to high levels of blood glucose. It promotes glucose uptake in cells and decreases catabolism.
c) This hormone is produced in the Kidney in response to stress. It preserves blood glucose and stimulates protein and fat breakdown.
d) This hormone is primarily responsible for building lean tissue in the body and is produced in the testes and also in the adrenal glands of both men and women.

EXTRA CREDIT
Describe in 100 words or less, the path a carbohydrate takes before it becomes a unit of directly usable energy. Highlight any processes and organs involved in the process.
*************
Answer:
When we consume carbohydrates, a small portion of the carbohydrate is acted upon by amylase in the mouth, when it is swallowed into the stomach, some of the simple sugars that are in the food are transfered by the blood stream to the liver and cells that can process these sugars, the majority of the carbohydrate is further ground in the stomach and passes through the duodenum into the small intestine where it is completely broken down into simple sugars which are transported by the Portal vein to the liver. depending on needs, the liver will either distribute the simple sugars, break them down further, or combine them to form glycogen. Glucose and glycogen are the two main forms of carbohydrate based energy precursor and thus you didn't need to put anything else, but if you wanted to you could have said, using insulin, cells absorb these molecules where mitochondria take them up and using oxygen and other molecules (phosphorus mainly) create ATP (Adenosine Triphosphate), the result of which is free energy).
