NUTR SCI 132 Exam 3 Study Guide Lectures 21 30 NUTR SCI 132 Lecture 21 Describe the differences in the stresses and benefits between Aerobic Exercise and Strength Resistance training What is the FIT training principle What rule should one follow when trying to improve physical fitness What is the difference between ADP and ATP How is the Immediate Energy System used What is the body s best form of energy How is Carbohydrate broken down into energy during exercise Describe the two pathways What is B oxidation and what is it used for Lecture 22 How can we predict the source of fuel the body will use Match the following with the correct source 1 Rest to light work 2 Max Intensity Short Duration 3 Near Max Intensity A 80 90 CHO B 70 90 Fat C Immediate Energy System CHO protein or fat How does training altar improve the body s response to exercise Which 2 nutrients should physically active focus on eating more of Lecture 23 Why is protein important to eat 20 30 min after exercise Describe some of the unique properties of water What is homeostasis Why is it important Lecture 24 In what 3 cases is thirst not a reliable mechanism for regulating maintaining fluid balance How is water distributed within the body What is Osmosis How is water lost from the body And how much per day What is Chloride And what are its functions Sources of it What is Potassium Functions Sources What is Sodium Functions Sources Describe the negative effects of excess sodium intake Describe the 4 possible stages of Heat Stroke Lecture 25 What are the risks of overhydration What should one consume after exercise Why Name 2 groups of paired nutrients How do they interact with one another Create a Venn Diagram mapping the relationship between Vitamin and Minerals Vitamins Both Minerals Lecture 26 What is a metalloenzyme Match the following Micronutrients with their respective descriptions 1 Zinc 2 Iron 3 B 12 4 Folate 5 Potassium 6 Sodium 7 Calcium 8 Chromium 9 Pyridoxine B 6 10 Vitamin C A Enhances Insulin binding B Deficiency causes neurological problems water soluble vitamin that can have toxicity problems C Important for Na K exchange Loss leads to decreased exercise capacity and cramping D Positive intracellular ion involved with nerve cells and muscle contraction E Mineral important for gene expression cell division wound healing growth strength gains and Immune Response F Critical in pregnancy to prevent neural tube defects important in DNA synthesis and cell division G Store in bone necessary for muscle contraction H Enhances Immune Response neurotransmitters prevents scurvy I Deficiencies lead to learning disabilities component of Myoglobin in red blood cells and myelin sheath protective wrap around nerves J Deficiency causes pernicious anemia which can be caused by a low intrinsic factor activates folate component of myelin sheath What is the role of antioxidants Are all antioxidants the same What is a provitamin What is anemia and what are its symptoms What is the difference between pernicious macrocytic and microcytic anemia Lecture 27 What is the most common mineral deficiency Toxicity How is Iron stored Transported Why What two groups have increased need for iron What two factors affect Iron absorption What does Vitamin K help with Describe the B vitamins generally What is Pellagra Which B vitamins are rare to have a deficiency What is Beri beri What are osteoblasts and osteoclasts What do they do Why What are the 3 functions of Calcium Lecture 28 What happens when an individual has low blood Calcium What is Rickets What factors affect bone health What is Osteoporosis Osteomalacia What is the best strategy for avoiding complications from Osteoporosis in old age Lecture 29 What is the best way to ensure adequate micronutrient intake why What vitamins are widespread in food sources Limited in distribution Which vitamins are fat soluble What is the provitamin to vitamin A How does the body obtain Vitamin D What is melanoma and what kind of sun exposure causes it Match the following vitamins and minerals with their respective food sources Note food sources may be used more than once and some vitamins minerals may have more than one source VITAMINS MINERALS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Vitamin E Riboflavin Vitamin K Folate Vitamin C Sodium B Vitamins general Chloride Potassium Calcium Vitamin B 12 Thiamin Niacin Vitamin D Zinc Iodine Magnesium Iron FOOD SOURCES A B C D E F G H I J K L M N O Orange juice Salt Meat fish poultry milk Fruits and vegetables Milk Dark Leafy Greens Sesame Whole grains Proteins Fish oil Seed Oils Seafood Vegetables Dried Fruit Cookware Lecture 30 What are the forms of Iron in foods Which type is more bioavailable How does cooking affect vitamins minerals What are the causes of deficiency ANSWERS Lecture 21 Describe the differences in the stresses and benefits between Aerobic Exercise and Strength Resistance training Aerobic rhythmic repetitious use of large muscles that demands lots of Oxygen and energy Benefits cardiovascular system Strength Resistance Isolates muscles Increase BMR and muscle mass What is the FIT training principle Frequency 3 5 days Intensity 60 80 max Heart Rate Time 20 30 min What rule should one follow when trying to improve physical fitness Don t increase by more than 10 per week What is the difference between ADP and ATP ADP converted to ATP by adding a Phosphate Energy can be stored as ATP How is the Immediate Energy System used For less than 10 second bursts Creatine Phosphate used What is the body s best form of energy Muscle glycogen body fights to preserve How is Carbohydrate broken down into energy during exercise Describe the two pathways 6 Carbon glucose molecule broken down into two 3 Carbon pyruvate molecules in process called anaerobic glycolysis without Oxygen If Oxygen is available the Pyruvate is further broken down into Carbon Dioxide and Water If Oxygen is not present the pyruvate will turn into lactic acid The lactate is eventually sent to the liver and turned back into glucose What is B oxidation and what is it used for Fat burned for energy at lower intensity exercise No lactate produced only carbon dioxide and water Lecture 22 How can we predict the source of fuel the body will use Match the following with the correct source Duration and Intensity of Activity 1 Rest to light work B 2 Max Intensity Short Duration 3 Near Max Intensity A C A 80 90 CHO B 70 90 Fat C Immediate Energy System CHO protein or fat How does training
