How many calories is a pound of fat? Correct Answer-Equivalent to 3500 calories What are the 3 components of total energy expenditure? Correct Answer-70% Resting metabolic rate (RMR) , 10% thermic effect of food (TEF), & 20% Physical activity make this Name at least 4 factors that affect RMR (resting metabolic rate) Correct Answer-1) Body size 2) Body composition 3) Age 4) Hormones (book says gender, but they're getting at hormones); e.g., burn more cals when you are on your period ...

Energy sources - Carbs and protein= 4 cal/gram; fat= 9 cal/gram; the brain uses glucose for energy, uses ketone bodies during starvation Tissue storage of glucose - Muscles and liver= store glycogen; adipose tissue= fat; cellular mass= protein stores Gluconeogenesis= conversion of non-carb sources into glucose by glycerol and amino acids Homeostasis - Keeps the internal environment/temp of the body at a state of equilibrium Cellular oxidation - Enzymes= proteins, organic catalysts tha...
