Insulation from clothing and shelter reduces heat loss.
In the deep organs, especially the liver, brain, and heart, and in skeletal muscle contractions.
Dehydration kills far quicker than starvation.
Evaporation.
Relative amount of body surface area.
Chemical changes in tissue cells that result in the combustion of foodstuff, releasing heat and energy.
The minimum amount of energy needed to maintain life processes.
5-10%.
Temperature, humidity, and movement of air.
Convection, conduction, radiation, and evaporation.
Basal metabolism, physical activity, specific dynamic action of foodstuff, and other factors like growth, pregnancy, and lactation.
1 calorie = 4,184 joules.
The set of chemical reactions that occur in a cell, enabling it to keep living, growing, and dividing.
Basal metabolic rate, thermic effect of food, and energy expended in physical activity.
The disposal of electrons released by glycolysis and the citric acid cycle, allowing energy to be stored as ATP.
The energy associated with motion.
The oxidation of glucose to obtain ATP.
The breakdown of fatty acids into acetyl-CoA for use in the Krebs' cycle.
90-95%.
An important aspect of homeostasis that regulates body heat.
In the mitochondria with the presence of oxygen.
It can increase heat loss.
The study of how organisms manage their energy resources via metabolic pathways.
60-70%.
It limits sweat evaporation and thus heat loss.
Energy expenditure must exceed energy intake.
Energy is the capacity for doing work.
The body can lose heat by radiation and conduction.
Respiration, circulation, glandular activity, maintenance of body temperature, and muscle activities.
The hypothalamus.
Age, sex, body composition, and physical activity level.
The process of disposing of NH4+ in less toxic forms.
Energy stored in the location of matter, including chemical energy in molecular structure.
The oxidation of acetyl-CoA to obtain GTP and valuable intermediates.
To stay alive, grow, keep warm, and move around.
It prevents heat loss because fat is a good insulator.
Energy is necessary for life processes, movement, and carrying out daily tasks.
The synthesis of glucose from smaller precursors for use by the brain.
A term used in measuring energy, defined as the amount of heat required to raise the temperature of one gram of water by one degree centigrade.
Carbohydrates, proteins, and fats.
The production of new cell components, usually requiring energy and reducing power from nutrient catabolism.
Catabolism and anabolism.
The process of obtaining energy and reducing power from nutrients.
Energy derived from food and energy expended in physical activity.
37 degrees Celsius.
A metabolic pathway for the synthesis of pentoses and release of reducing power needed for anabolic reactions.
