Exam 3 Review NUTR 104 Chapter 7 Alcohol Does drinking too much alcohol interfere with the absorption of several vitamins and minerals? YES Does long term alcohol consumption contribute to malnutrition? YES Does the human body store alcohol? NO A standard drink is defined as? contains roughly 14 grams of pure alcohol, which is found in: 12 ounces of regular beer, which is usually about 5% alcohol. 5 ounces of wine, which is typically about 12% alcohol. 1.5 ounces of distilled spirits, which is about 40% alcohol. Does alcohol require digestion? NO Dose alcohol travel through the lymphatic system before entering the blood stream? NO What vitamin is required in the alcohol dehydrogenase pathway to metabolize alcohol? Niacin Where is alcohol metabolized and where does most absorption occur? Small intestine into veins to liver What enzyme metabolizes alcohol in the stomach? ADH and ALDH Does is take several hours for alcohol to reach the brain? No – 5 minutes Does too much alcohol interfere with the body’s ability to metabolized drugs? yes Chapter 8 Metabolism Aerobic metabolism and components - Aerobic metabolism is part of cellular respiration and involves your cells making energy through glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation. There is detailed chemistry involved in how the body produces energy for exercise. Molecule that is the Gateway for Aerobic Metabolism - Acetyl CoA Site of Aerobic and Anaerobic Metabolism Examples of catabolic and anabolic reactions Process of Glycolysis The stage of the metabolic process that generates the most ATP’s (you do not need to know the number of ATP’s) Which nutrients have the ability to convert to glucose Body’s primary source of fuel - Carbohydrates Function of Creatine phosphate Production of lactate Metabolic Fate of Energy Producing NutrientsWhich components of the triglyceride molecule is ketogenic /glucogenic Ketogensis and Ketoacidosis Cori cycle 1 Beta Oxidation Role of the Electron Transport Chain - to transfer energy from the electron carriers to even more ATP molecules, the "batteries" which power work within the cell. Summary of Metabolic Process Table 8.4-page 300 Metabolism during Feasting and Fasting Table 8.5 page 305 Genetic Disorders of Metabolism Table 8.6 page 306 Chapter 14 Energy Balance and Body Composition 1 lb. of body fat=3500 Kcal/ Excess kcalories required to gain weight How is excess energy stored in the body - Excess glucose beyond what the body needs for immediate energy is converted into glycogen, a storage form of carbohydrate, or converted into fat and stored in body fat cells. Requirements for Total daily energy expenditure (TDEE) - by adding four numbers together: basal metabolic rate, thermic effect of feeding, exercise energy expenditure, and non-exercise activity thermogenesis. Know the TEE, TEF, and NEAT Know the difference between BMR and RMR - While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it's at rest. Factors considered when using the Harris Benedict equation - gender, body weight, height, and age. Components of Energy Expenditure: 1. basal metabolism 2. physical activity 3. thermic effect of food 4. adaptive thermogenesis Know the factors affecting the BMR o o o o o o o o Muscle mass. The amount of muscle tissue on your body. ... Age. As you get older, your metabolic rate generally slows. ... Body size. ... Gender. ... Genetics. ... Physical activity. ... Hormonal factors. ... Environmental factors. BMI- what is considered overweight, underweight and acceptable - < less than 18.5, is underweight range. 18.5 to 24.9, is normal or Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, = obese range. Healthy/Acceptable Weight Circumference for men and women - For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high. Know the difference between android and gynoid obesity and why does one of those increase the risk of chronic diseases - Obesity of the male (android) type shows a dominant visceral and upper thoracic distribution of adipose tissue, whereas in the feminine (gynecoid) type adipose tissue is found predominantly in the lower part of the body (hips and thighs). 2 Chapter 15Weight Management Define appetite, hunger, satiety, satiation The nutrient considered the most satiating - PROTEIN Cholecystokinin and peptide YY Review the functions of Ghrelin and leptin - Leptin is a mediator of long-term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Ghrelin on the other hand is a fast-acting hormone, seemingly playing a role in meal initiation. Define, know the health consequences, and treatment associated with eating disorders Eating Disorders are most common in which group of people - Teenage girls and young women Recommendations for moderate physical activity - 150 minutes of moderate-intensity physical activity and 2 days of muscle strengthening activity. at least 30 minutes of moderate physical activity every day. Reasonable rate of weight loss & the key to successful weight loss – 1 to 2 pounds/week. Exercise helps Hyperplasia and hypertrophy - Hypertrophy refers to an increase in the size of individual muscle fibers, whereas hyperplasia refers to an increase in the number of muscle fibers. What occurs with the fat cells when an individual loses weight - fat cells shrink in size as their contents are used for energy, but the number stays the same. The activity of lipoprotein lipase (LPL) in men and women - In the 3 to 4 hours after exercise, muscle and adipose tissue LPL activity increased significantly in men, whereas LPL activity remained unchanged in women. Question 5 (1 point) Saved Anabolic reactions combine smaller molecules into larger ones. Question 5 options: True False Question 6 (1 point) Saved Catabolic reactions break large molecules into smaller ones. Question 6 options: 3 True False Question 7 (1 point) Saved ATP is composed of all of the following except Question 7 options: ribose. adenine. three phosphate groups. tyrosine. 4
