Basal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.
Which of the following definitions best describes an individuals Basal Metabolic Rate? The amount of energy used while eating. O The amount of calories required to support an active lifestyle. O The ratio of total cholesterol / HDL. ( The number of calories to keep a body functioning at rest.
Your body stores energy in the form of fat and other organic molecules. When your body needs extra energy, it breaks apart the molecules of fat to release that energy (sometimes called "burning fat"). That energy is used to power cellular reactions or is lost as heat. The total amount of energy used by your body or lost as heat equals the amount of energy the molecules of fat originally stored before breaking apart. This process is an example of the _________law of thermodynamics. A. first B. second
Homeostatic systems maintain a steady-state set point over time using negative feedback. Which one of the following statement is NOT TRUE for stability of metabolic system: Select one: O a. A positive feedback system is stable over time, maintaining a steady state O b. Metabolic systems that oscillate must have multiple control variables O c. Step changes in a controlled variable will return the system to its original state using negative feedback O d. Perturbations from steady state, either positive or negative, result in recovery reactions that return the system to its original state
Smaller cell is: A less active metabolically B with larger nucleus C with smaller nucleus D more active metabolically
When cells break down food (glucose) molecules during cellular respiration, energy is released in the form of heat and stored temporarily as ATP. released entirely as body heat into the environment. released quickly. stored temporarily in ATP molecules.
The most significant determinant of basal metabolic rate is: O age sex total muscle mass versus fat mass O activity levels
Directions: Complete the paragraph below to explain why your body gets warm during a workout. When you workout, your cells need for muscle contraction. In order to get this, your body will carry out a process called During this process, (from food) is broken down in the presence of to make the usable form of energy for cells, called This process converts energy from the bonds of food molecules into energy that is (potential energy) in ATP molecules. The process also releases (thermal) energy, which is why you feel warm. Your body carries out this amazing process to fuel your workouts! :: cellular respiration : energy : ATP :: glucose : oxygen :: chemical :: stored :: heat
Which of the following is the most comprehensive definition of metabolism in living organisms? Metabolism manages the increase in entropy in an organism Metabolism consists of all the energy transformation reactions in an organism Metabolism refers to the sum of all biochemical pathways involved in the synthesis of macromolecules Metabolism depends on a constant supply of energy from food
How much of the energy we consume goes towards supporting the body’s basic functions? a 20% b 10% c 70% d 35%
