NHM 101 1nd Edition Lecture 12 Outline of Last Lecture I. Characteristics of fats and oilII. Lipid digestion and absorption III. Functions of lipidsIV. Fat recommendations Outline of Current Lecture V. Feasting and FastingVI. Metabolism Current LectureFeasting- Over consumption - Extra stored glycogen and body fat- Acetyl CoA turned back into body fatFasting- Short Term Fasting (1 day)o Breakdown of glycogen- Fasting for 2-5 Dayso Break down of lean tissueso Amino acids and glycerol converted to pyruvate and then glucose - Long Term Fasting (week or longer)o Breakdown of fat for fuelo Acetyl CoA build up and converted to ketones - METABOLIC RATE DECREASES Metabolism- Sum of all chemical reactions in cells- Energy metabolismo All chemical reactions in which the body obtains and expends energyo Coenzymes required in almost all metabolic reactions These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- ATP high energy compound- Anabolism creating somethingo Ex: Condensation- Catabolism breaking something apart o Ex: hydrolysis - Nutrient compounds used to produce energyo Carbohydrates 4 kcal/gramo Proteins 4 kcal/gramo Fats 9 kcal/gram- Aerobic requires oxygen to make ATP- Anaerobic quick energy; does not require oxygen- Pyruvate 3 carbon compound- Acetyl CoA 2 carbon compound - Krebs Cycle (TCA Cycle) metabolic reactions breaking Acetyl CoA into CO2- Electron transport chain final pathway of energy
