The body is made up of
|
Atoms, ions, and molecules.
|
|
Life processes depend on the organization and interaction of
|
Atoms,ions, and molecules
|
|
An electrically charged atom or group of atoms
|
Ion
|
|
Because of their electrical charges, ions are very important in many life processes, including
|
Energy tranformations, transmission ofnerve impluses, and muscle contraction.
|
|
Is a molecule that consists of two or more different elements combined in a fixed proportion.
|
Chemical compound
|
|
Chemical compounds can be classified in two broad groups
|
Inorganic and organic
|
|
Are relatively small, simple compounds such as water , salts, simple acids, and simple bases.
|
Inorganic compounds,These substances are required for fluid balance and for many cell activities such as transporting materials through cell membranes.
|
|
Are large, complex compounds containing carbon.
|
Organic compounds,they are the chemical building blocks(structural componets) of the body also serve as fuel molecules that provide energy for body activities, also regulate and participate in thousands of chemical reactions necessary for life.
|
|
Are sugars and starches
|
Carbohydrates, they are used by the body as fuel molecules and to store energy
|
|
Glucose is a simple sugar that is a main source of energy for
|
The body
|
|
The liver and musc les can link glucose molecules into long chains, producing
|
Glycogen, a large molecule that can be stored.
|
|
Four important groups of inorganic compounds are
|
Carbohydrates,lipids,proteins,and nucleic acids.
|
|
Among the biologically important groups of lipids are the
|
Fats, compounds that store energy, and phospholipids, which are components of cell membranes. Steriods.
|
|
Another important group of lipids , include several hormones, for ex female sex hormones.
|
several hormones, for ex female sex hormones.
|
|
Are large complex molecules composed of subnuits called amino acids.
|
Proteins
