3A_Biomolecules

//** Living systems are complex and highly organized, and they require matter and energy to maintain this organization. **// This balance is achieved through various biogeochemical cycles and the processes of photosynthesis and cellular respiration - // focus is on ENERGY
 * ENERGY, MATTER & ORGANISATION - ** BIOMOLECULES
 * ** Energy ** is stored in the organization of matter
 * Fats can be broken down into carbon, hydrogen and oxygen.
 * Living organisms use matter and energy to build and maintain body structures
 * Humans drink milk which is rich in calcium. Calcium is essential to healthy bones and bones maintain body structures.
 * Meat is rich in protein. Protein is used to build muscles.
 * Living organisms obtain and process matter and energy
 * Living organisms process food or minerals for energy. Fats can be broken down into carbon, oxygen and hydrogen in animals.
 * The structure of a molecule always dictates its function.
 * The structure and function of biological living systems obeys the laws of thermodynamics.
 * Communities of organisms depend on the cycling of matter and the flow of energy
 * Carbon cycle
 * Water cycle
 * Nutrient cycle
 * The constant flow of energy and cycling of matter in the biosphere leads to a balanced or steady state.
 * Water cycle is necessary
 * NOTE: ENERGY DOES NOT FORM A CYCLE. IT IS CONVERTED TO ONE FORM TO ANOTHER. ONLY MATTER IS CYCLED.

//
 * 1) Are we just chemicals?
 * 2) Are we what we eat?
 * 3) Why is the carbon molecule suitable for life as we know it?
 * It has 4 electrons in its outer shell, has a unique capacity to form many bonds (single, double or triple)
 * It can form bonds with other molecules of carbon (It can create a carbon backbone, a long chain of molecules)
 * Can form many structures and varying levels of complexity
 * It is the 4th most abundant element
 * 1) Why is the chemistry of water suitable for life?
 * Below 4 degrees Celsius, it expands. Making it able to float in its solid form due to a lower density.
 * // It is an universal solvent //
