Study Notes

Energy Balance

Energy balance occurs when energy intake equals energy expenditure.
The result of homeostatic control in energy balance is a stable body weight.
Energy balance is achieved when the energy intake from the diet equals the energy expenditure from the body's metabolic processes.

Factors Affecting Energy Balance

Fluctuations in body weight occur when there is a mismatch between energy intake and energy expenditure.
Energy balance can occur in individuals with different activity levels, but it requires adjustments to energy intake to match their energy expenditure.

Carbohydrate Digestion

Salivary amylase is the enzyme responsible for the initial breakdown of starch in the mouth.
The primary action of salivary amylase on starch is to break it down into smaller molecules, such as maltose and dextrins.
Mastication (chewing) in the mouth helps to mix carbohydrates with salivary amylase, increasing the surface area for digestion.
The small intestine is responsible for the digestion of monosaccharides.
Specific enzymes, such as lactase, sucrase, and maltase, are involved in the breakdown of carbohydrates into absorbable monosaccharides.
