Concept explainers

Nutrition and Digestion

The process of consuming nutrients to utilize them for various biological purposes is known as nutrition. The substances absorbed from food are known as nutrients. They serve different important functions in the body, such as repairing wounds and damages, generating energy for metabolism, and regulating biochemical reactions.

Question

Well over half of the human body’s energy is devoted to which of the following?
A. Basal metabolism
B. Muscle contractions
C. Brain activity
D. Keeping the heart going

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

At rest, how much body energy is used by the skeletal muscles and the heart .a 25% .b 24% .c 19% .d 20%
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.
