Question

Abbreviation BMR in biology stands for
(a)Birth mortality rate
(b)Basal metabolic rate
(c)Bone marrow regeneration
(d)All of above

Answer 1

Hint: BMR is the number of calories burned by the body during complete rest. Determining the BMR helps in monitoring calorie intake, this is an essential health-monitoring tool.

Complete answer:
The term BMR stands for Basal Metabolic Rate. A resting body will burn calories because energy is needed for different physiological functions of the body such as cell repair, circulation of blood and body fluids, respiration, etc. BMR is age-dependent and decreases with an increase in age. Hence, when a person grows older it needs lesser calories to maintain a healthy BMR. In teenagers, the BMR is at peak levels and the body needs more energy to maintain its vital functioning. BMR is calculated by Harris-Benedict formula, given by:
$P= (10.0\times m/1 kg) + (6.25\times h/1 cm) - (5.00\times a/1 year) + s$
Where,
P= Total energy released during rest
m= weight of the person in kg
h= height of the person
a= age of the person
s= constant, +5 for male and -161 for females

Additional Information:
 -James Arthur Harris and Francis Gano Benedict introduced the term BMR.
-The other name of BMR is Basal Energy Expenditure(BEE).
-According to WHO, BMR of 25 is considered healthy.
-BMR can be increased by regular exercise and drinking plenty of water.
So, the correct answer is, ‘Basal Metabolic Rate.’

Note: The diet experts use BMR as a tool for determining the obesity-related issues of his patient. BMR depends on age, nutrition, physical activity, amount of fat stored, and the body size of a person.
