Study Notes
Energy Production and Metabolism
- Equivalent of human energy in muscle contractions and heat production denotes metabolic processes during physical activities.
- Anabolic phase involves smaller molecules becoming larger and more complex through biosynthetic pathways.
- Catabolic phase concerns the breakdown of larger molecules into smaller ones, releasing energy.
Digestive Processes
- Mechanical digestion involves the physical chewing of food and the churning action performed by the stomach and intestines.
- Segmentation refers to the rhythmic contractions in the intestines, promoting food mixing and nutrient absorption.
Energy Expenditure
- The largest component of total daily energy expenditure is known as Basal Metabolic Rate (BMR), which accounts for 60%-75% of energy use.
- Total Daily Energy Expenditure (TDEE) refers to the overall energy expended in a single day.
Nutritional Deficiencies
- Iodine deficiency affects 780 million people globally and can lead to thyroid-related disorders.
- The most prevalent form of malnutrition worldwide is protein-energy malnutrition, affecting millions, especially in underdeveloped regions.
Body Type Characteristics
- A body type characterized by a high forehead, receding chin, and low muscle and fat is known as ectomorphic.
- Android/Apple shape body type features fat accumulation in the hips, abdomen, and thighs, posing risks to organs like the kidneys and uterus.
- The major risk for an Android/Apple shape body type includes increased likelihood of cardiovascular diseases and metabolic syndromes.
Severe Weight Loss
- Extreme weight loss and body wasting associated with serious illness is referred to as cachexia, often seen in chronic diseases.
Absorption in Digestion
- Absorption in the digestive system refers to the process where nutrients from digested food are taken up by the intestinal walls into the bloodstream.
Symptoms of Nutritional Deficiencies
- The most common symptom of iodine deficiency typically involves goiter or hypothyroidism symptoms, reflecting thyroid dysfunction.
