//Eg: //
 * **Energy ** is stored in the organization of matter.
 * **Energy ** is stored in the organization of matter.
 * Living organisms use matter and energy to build and maintain body structures
 * Living organisms obtain and process matter and energy

> //Eg: // //Proteins to build muscles. Snake needs to consume certain food to form the structure that it needs (skin). // //Eg: // Plasma membrane - Polar and non-Polar (repels and attracts water) //Eg: Energy does not form a cycle. It is a conversion of energy that forms to one system to another. // > This balance is achieved through various biogeochemical cycles and the processes of photosynthesis and cellular respiration - //focus is on ENERGY //
 * The structure of a molecule always dictates its function.
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">The structure and function of biological living systems obeys the laws of thermodynamics.
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Communities of organisms depend on the cycling of matter and the flow of energy
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">The constant flow of energy and cycling of matter in the biosphere leads to a balanced or steady state.

(2) It has free electrons and it can form a stable structure. It can form bonds not only with others but itself. C-C-C-C-C-C-C It is able to form a long chain of DNA. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Eg:
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Are we just chemicals?
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Are we what we eat?
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Why is the carbon molecule suitable for life as we know it?
 * <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Why is the chemistry of water suitable for life?

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">Fats are formed by carbon, hydrogen and oxygen.

(2)Role:

-Supply Energy <span style="font-family: Arial,Helvetica,sans-serif; font-size: 14px; line-height: normal;"> <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">The body uses carbohydrates directly from the monosaccharide glucose. Glucose is in the blood and extracellular fluids (lymph) and can be made from glycogen. Glycogen is stored in the liver and muscles and in smaller amounts in the other organs and tissues of the body. Energy is derived from glucose by the splitting of the glucose molecules into smaller compounds and oxidizing these to form water, which frees quite a large amount of energy. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 90%;">When carbohydrates needed for the functioning of the central nervous system, the muscles and the other body systems and functions are insufficient in the diet (as during a fast or on a weight-loss diet), stored adipose tissue (fat) is broken down into glucose to make up the caloric deficit. Some amino acids, instead of being used to make proteins, are deaminated and used as carbohydrates to supply energy. The formation of glucose from amino acids is called gluconeogenesis. This phenomenon enables one to maintain normal blood sugar levels during a fast.
