Metabolism Review ll Human Physiology 1. Define calorie. Contrast calorie and kilocalorie (Calorie) 2. If you ingest, digest, absorb, and metabolize a slice of bread, the energy released from the bread equals about 80 to 100 (calories? kcalories?). 3. Define basal metabolic rate (BMR) consumed BMR may be determined by measuring the amount of within a period of time, because oxygen is necessary for the metabolism of foods. Normally, for each liter of oxygen consumed, the body metabolizes enough food to release heat in that hour. At this metabolic rate, you would need to consume to meet your metabolic needs. 4. kcal of kcal per day A BMR of 20% below the standard value is likely to be due to a condition called thyroid. 5, 6. Explain why elderly persons are at a greater risk for hypothermia.Explanation / Answer
1. Calorie is the unit of energy. Calories refer to the energy aquired from food and drinks and the energy burnt in physical exercise.
One calorie is the amount of energy required to raise the temperature of one gram of water by10 Celsius.
One kilocalorie is the amount of energy required to raise the temperature of One kilogram of water by 10 Celsius.
1 kilocalorie = 1000 calorie
2. kilocalories
3. Basal Metabolic Rate (BMR) is the amount of energy required to keep the body functioning in a state of rest.
4. BMP may be determined by measuring the amount of calories consumed within a period of time, because oxygen is necessary for the metabolism of foods. Normally for each litre of oxygen consumed, the body metabolzes enough food to release 4.7 kcal of heat in the hour. At this metabolic rate you would need to consume 1800 kcal per day to meet your metablic needs.
