PHSL 3051 Lecture Notes - Lecture 36: Glycogenesis, Gluconeogenesis, Digestion
Document Summary
Energy, atp, amino acids, fats, proteins, etc. Sum of all chemical reactions in the body. Atp, flexing muscles, beating heart, diaphragm contraction. Anabolic pathways synthesize larger molecules from smaller ones. Catabolic pathways break large molecules into smaller ones. Nutrient pools are pools available for immediate use. Not stored, used for protein or breakdown. Stored in liver and skeletal muscle (small amount) Must be dissolved - requires lots of water, makes it heavy. Fats have more than 2x the energy content of an equal amount of carbohydrate or protein. Energy in fats is harder and slower to access. Know movement of glucose, amino acids, and triglycerides. Glucose (bloodstream) if glucose is available and abundant, cells will use this to make atp before using fats. Deamination step to form keto acids removes amino group. Stored as triglycerides (made from glucose, lipoproteins (liver), or directly from bloodstream) ldl = vldl (low density lipid) Vldl"s can also dock onto other tissues.
