Study Notes

Basal Metabolic Rate (BMR)

BMR is the energy required by the body at rest to perform essential functions.
Essential functions include breathing, circulation, and cell production.
BMR is influenced by factors such as age, sex, body composition, and genetics.
BMR represents the largest portion of daily energy expenditure.
Daily energy expenditure excludes energy used for physical activity and digestion.

Metabolic Processes

Metabolism involves a set of chemical reactions that convert food into energy for cellular processes.
Metabolism consists of two primary components: catabolism and anabolism.
Catabolism involves breaking down molecules to release energy.
Anabolism involves building up molecules for growth and repair.

Importance of Metabolism

Metabolism is essential for maintaining vital functions.
Metabolism is crucial for overall health.
