Water is also known as H2O. I am made of two Hydrogens and one Oxygen. I love to travel and can be found in every home in the United States. I can change into many different shapes and can go almost anywhere if I am given the chance. My story starts in a well in my back yard at my home. I come from an underground aquifer. I can travel through the pipes into my kitchen faucet. I have many uses. I can be hot‚ warm or even cold. I can be mixed with dish soap in the kitchen sink or ran through

and numerous organic and inorganic molecules‚ which are the solutes‚ or dissolved substances. Organelle membranes and the plasma membrane are selectively permeable‚ allowing water to freely pass through but regulating the movement of solutes. The cell actively moves some dissolved substances across membranes‚ expending adenosine triphosphate (ATP) (biological energy) to accomplish the movement. Other substances move passively‚ without expenditure of ATP from the cell‚ but only if the cell membrane

Metallobiomolecules METALLOBIOMOLECULES CONTENTS 1. Introduction Metallobiomolecules 2. Classification Metallobiomolecules 2.1. Transport and of to Storage Proteins 2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this‚ new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

Lung Cancer the silent killer Lung cancer is the leading cause of cancer-related mortality not only in the United States but also around the world (Humam Kadara‚Mohamed Kabbout‚&Ignacio Wistuba ‚2011). Lung adenocarcinomas are a major subtype of non-small-cell lung cancers‚ are increasing in incidence globally in both males and females and in smokers and non-smokers‚ and are the cause for almost 50% of deaths attributable to lung cancer and the high mortality of this disease is in part due to the

Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides- Two

Obstructive Pulmonary Disease Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that makes it intensely difficult to breathe. This disease affects millions of Americans and affects tens of millions of people around the world (Jones‚ 2001). With COPD‚ the tissue where oxygen is exchanged is destroyed due to the thickened and inflamed airways in the lungs. This decreases the flow of air coming in and out of the lungs. When this occurs‚ body tissues receive less oxygen making it

How are they alike‚ and different? Is one more efficient than another? Gills/Lungs?HumansIn humans air travels into the mouth‚ or nose‚ and into the nasal cavity‚ followed by pharynx. The pharynx is where food and air cross paths. The pharynx increases the chance of choking‚ but also allows breathing when exercising and respiration though the mouth‚ if the nose is closed. Next‚ epiglottis opens allowing air to move into the glottis‚ and pass the larynx (voice box). After this air makes its way into

CHAPTER I Introduction Background and Rationale of the Study Tuberculosis (TB) is an infectious disease that primarily affects the lung parenchyma caused by slow-growing bacteria that resembles a fungus. It is usually spread from person to person by droplet nuclei through the air. The lung is the usual infection site but may also be transmitted to other parts of the body‚ including the meninges‚ kidneys‚ bones‚ and lymph nodes. The primary infectious agent‚ Mycobacterium tuberculosis‚is an

Lung Capacity in this lab‚ I learned about lung capacity and CO2 production. Lung capacity simply means the maximum amount of air you can take into your lungs. Lung capacity and CO2 production closely relate to the respiratory system. The respiratory system is the system in which oxygen goes into your body and carbon dioxide comes out; In short it’s breathing. The structures involved in the respiratory system are mouth/nose‚ mucus/cilia‚ pharynx‚ larynx‚ bronchi‚ bronchioles‚ alveoli‚ pleura‚ and
