KINS 1100 Lecture Notes - Lecture 4: Glycerol, Triglyceride, Glycolysis
Document Summary
Bioenergetics: the flow and exchange of energy within a living system. Internal energy of an isolated system is constant. Energy can be transferred , but neither created nor destroyed. The total of all energy transformations that occur in the body. Fats (fatty acids + glycerol), carbs (glucose), and proteins (amino acids) Glycogen: takes less spaces and works as a storage of glucose (w/in skeletal muscle and liver) Beta-oxidation: free fatty acid that is broken down into multiple pairs. Minor energy source (via deamination or transamination processes) Support, coordination & control, movement, transport, metabolic regulation, defence. Atp can be re-synthesized from adp and pi through: Provides energy for 2 mins of resting physiological function or 3 secs of maximal effort. Atp + h 2 o adp + inorganic phosphate + energy. Stored cp is enough to support 20-30 secs of maximal exercise. The breakdown of glucose to pyruvate (pyruvic acid) 2 pyruvic acid 2 lactic acid 2 lactate.
