The Basal Metabolic Rate (BMR) Is the Minimum Energy Intake

question 31

Essay

The basal metabolic rate (BMR) is the minimum energy intake required to maintain a body that is awake and at rest. While the rate varies with age, gender, health, and body mass, a reasonable value is 1600 Cal per day. Walking can require 2.5 times the BMR, and exertion in work or sports can require 7 times the BMR. Using this information, calculate the energy expended by someone walking at a speed of 3.0 mph and determine how far she could walk with the energy from a quarter-pound hamburger (125 g) that has a food value of 3.6 Cal/g.

Understand the interaction between environmental temperature and metabolic rate in animals.

Identify and describe the four basic types of tissues in animals.

Understand the structural and functional characteristics of connective tissues.

Understand the concepts of homeostasis and its mechanisms in the body.
