It has a number of roles in cells.  It takes part in some reactions, such as photosynthesis in plant cells, which supplies our earth with molecular oxygen, and respiration in both plant and animal cells, which produces energy.

_____ also absorbs and releases high levels of heat before its temperature changes, thus helping control normal body temperature.

It is part of amniotic fluid and protects the developing fetus.  It is also part of the cerebrospinal fluid and protects the brain and spinal cord by functioning as a shock absorber.

Finally, it is the base for all body lubricants such as mucus in the digestive tract and synovial fluid in joints.

A small molecule that contains one carbon atom covalently bonded to two oxygen atoms.  It is produced as a waste product of cellular respiration and must ne eliminated quickly from the body through expiration via the respiratory system and the cardiovascular system.

If ____ ____ is allowed to accumulate within the cells, it becomes toxic by forming carbonic acid as it reacts with water.  Hence we exhale it quickly from the lungs.

 Molecular Oxygen (O₂)

Formed when two oxygen atoms are covalently bonded together, is required by all organisms that breath air.

*  It is necessary to convert chemical energy (food), such as the
    energy found in a glucose (C₆H₁₂O₆) molecule into another form
    of chemical energy, ATP, that can be used by cells to do work.
* Without plants there would be no molecular oxygen in
   our atmosphere, and without O₂ there would be no life on our planet
   as we know it.

______ is an essential element in amino acids, which are the building blocks of proteins.

 Mineral Salts

__ __ are composed of small ions. They are essential for the survival and functioning of the body's cells.

* Calcium (C_a⁺) is necessary for muscle contraction and nervous
   transmission as well as strong bones. It is the fifth most abundant
   element in the body.

This book concentrates on fats which are a major kind of _____.

Of the fats in the human body, 95% are triglycerides, also called triacylglycerols.

Fats

A fatty acid is saturated if it contains only single covalent bonds such as those found in whole milk, butter, eggs,beef, pork, and coconut and palm oils.  Saturated fats tend to be solids at room temperature. Too much of these fatty acids contributes to cardiovascular disease.

If the carbon chain has one or more double covalent bonds between the carbon atoms, it is an unsaturated fatty acid.  These fatty acids are good for you and are found in sunflower, corn,  and fish oils. Unsaturated fats tend to be liquids at room temperature.

Adenosine Triphosphate (ATP)

high-energy molecule or fuel that runs the cell's machinery.  All the food we eat (which is a form of chemical energy) must be transformed into another form of chemical energy called ______ that allows our cells to maintain, repair, and reproduce themselves.

 Movement of materials into and out of cells

The plasma membrane of cells is a selectively permeable membrane.  This means that only selected materials are capable of getting into and out of cells.

The cell membrane is composed of an outer and inner layer of protein with a double phospholipid layer in between.  This chemical arrangement allows water to pass into and out of the cell with ease.

However water is not the only needed material needed for the cells survival.

Cells need food like sugars, amino acids to make proteins, and nutirents like the mineral salts. 

1. Diffusion
2. Osmosis
3. Active Transport

 Diffusion

The movement of molecules through a medium from an area of high concentration of those molecules to an area of low concentration of those molecules.Temperature has an effect on diffusion. The higher the temperature, the faster the movement.

Ex: Chunk of Ice: low temperature keeps the molecules moving very slowly, so the water is in a solid state. As temperature increases the water moves to a liquid state.

An example of an important diffusion in the human body is the uptake of oxygen by the blood in the lungs and the release of carbon dioxide gas to the lungs from the blood.

A special kind of diffusion.  ____ pertains only to the movement of water molecules through a selectively permeable membrane (e.g. a plasma membrane) from an area of high concentration of water molecules (e.g. pure water) to an area of low concentration of water molecules (e.g. water to which a solute such as sugar or salt has been added).

 Active Transport

The effects of Osmosis on Red Blood Cells

Isotonic Solution (normal saline solution): the salt concentration outside the red blood cell equals the salt concentration inside the red blood cell, water molecules will pass into and out of the red blood cell at an equal rate.

Hypotonic Soultion (pure distilled water): where the water molecules are in a higher concentration outside the red blood cell, water will move into the red blood cell, causing it to swell and eventually rupture.

Hypertonic Solution (5% salt solution): where there is more water inside the red blood cell than in the solution, the red blood cell will shrival up or crenulate.
