steps of cell cycle:  you should write a table showing the steps as well as the
FORM OF DNA
role of other organelles

1.  INTERPHASE -
a.  cell is undergoing growth.  After a period of growth, it prepares to divide
b.  cell replicates its DNA.  Nuclear membrane is still intact
2. PROPHASE
Nuclear membrane disappears and the chromosomes are visible
3.  METAPHASE
chromosomes line up in the middle and Centrioles send out the spindle fibres to attach to the centromere
4.  ANAPHASE
centromeres get ripped apart and thus the chromosomes get ripped apart into separate chromatids
5.  TELOPHASE
nuclear membrane reforms around the chromatids
6.  CYTOKINESIS
chromatin is in the nucleus now.

LESSON: Chemical reactions may be categorized as follows : 

1.     Synthesis

2.     Decomposition

3.     Single replacement

4.     Double replacement

5.     Combustion

       Cellular Respiration

6.     Oxidation of metals

Decomposition reaction:

Compound    -->   element     +     element

Or

Compound --> smaller compound    +   element

DOUBLE REPLACEMENT


single replacement

IN ADDITION TO THE FOUR TYPES ABOVE, THERE ARE ALSO THREE MORE KINDS of reaction TO KNOW: 

Combustion:  combustion may happen to any *organic compound* meaning any compound made of carbon, hydrogen and/or oxygen...

Carbon based compound+ oxygen --> carbon dioxide + water

+ heat and light energy

Cell respiration looks like combustion,

BUT IT IS NOT. YOUR CELLS ARE NOT COMBUSTING.  The carbon based compound in this case is glucose, a simple sugar.

Glucose +   oxygen -->  carbon dioxide + water + energy for cell

Oxidation reaction

Metal +  oxygen   -->   metal oxide

ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

In summary....

 

Liver Anyone?

 

In the human body, ENZYMES help speed up chemical reactions. 

Today we take a piece of raw pork liver and add it to Hydrogen Peroxide.  Raw liver contains an enzyme called "catalase" which has a job of breaking the bonds in hydrogen peroxide.  When those bonds are broken, atoms rearrange themselves and new products are formed.  

In today's lab, we discover the new products
