Document Summary
Metabolism is all of the life sustaining chemical reactions that occur in living. Energy metabolism- the chemical reactions that are involved in storing fuels or organisms that convert one molecule to another molecule breaking them down to produce atp. The sun is the source of all energy that sustains human life. Plants make simple sugars from co2 and capture the sun"s light energy in the chemical bonds. These foods provide energy or fuel to all living things. Fats (triglycerides) > glycerol and fatty acids. Molecules of glucose, glycerol, amino acids, and fatty acids. Catabolism breaks down to enter into pathways to produce atp. Energy is released when high energy phosphate in atp is broken. Atp is released during the breakdown of glucose, fatty acids, and amino acids. This energy is used to do most of the body"s work. Cells use the energy in atp molecules to power activity, synthesize compounds, and fuel active transport.
