The Subject is ATP -- Amazing Tremendous POWER!

  Otherwise known as adenosine triphosphate.  Here's the homework:

First of all, warm up with  the video we keep not having time for:  From Harvard University, 

The Inner Life of the Cell (music version)

(watch the 3-minute music version.) WOW!

Read text chapter 8.1: Energy & Life with study guide. Keep track of all the analogies mentioned.  ATP is like a ....what?  Post a comment.

http://www.khanacademy.org/video/atp--adenosine-triphosphate?playlist=Biology  {this video is advanced and contains hazardous amounts of chemistry} OR if you would prefer, you may instead spend the time in review on brainpop.com  and watch these five short movie clips: /http://www.brainpop.com/science/cellularlifeandgenetics 

log in (remember we wrote down the username/password in class) and follow the links to review.  cells, cell structures, passive transport, active transport. Read the FYI's, which are generally interesting and informative.

Lastly, make a model of the ATP molecule; it can be 2- or 3- dimensional, but not just a sketch.  At least cut up some paper and make it look cool.

 

ATP - Power To Drive Cellular Work

ATP - Adenosine triphosphate - a close relative to Adenine, a nucleotide found in DNA.

• Contains three phosphate groups connected to each other in sequence
• The bonds an be broken by hydrolysis
  • When the terminal phosphate bond is broken, a molecule of inorganic phosphate (P_i)  is formed
  • This forms adenosine diphosphate, ADP + (P_i)
  • This generates free energy, which can be used by the cell to do work
• Obviously, for the cell to function, ATP must rapidly be regenerated.
  • One muscle cell can consume and regenerate over 10,000,000 ATP's a second
  • If ATP couldn't be regenerated, humans would have to consume nearly their body weight in ATP each day
