Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).
The four types of organic compounds are carbohydrates, lipids, proteins and nucleic acids. Organic molecules contain the elements carbon and hydrogen, and they are found and made in living things. Keep Learning.
Understand the functions of the four major types of molecules https://www.youtube.com/watch?v=hYmuHdNzimI&list=PLi8sJ5jarQsyUiIn4rUA71ecODy3o9Md5&index=4 The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cellâs mass. Biological macromolecules are organic, meaning that they contain carbon.
