The Blog Site of Carl Sommerfeld

Today we paused the Andersen Video (check Moodle) on Enzymes (Topic 6 and Chapter 6) to discuss what an Enzyme is and what it does.

Popquizzes, to check on general comprehension of main ideas, could include topics like the “induced-fit” model; activation and inhibition of enzymes; keyterms like substrate and enzymes; active and allosteric sites on enzymes; everything until 10:15 of the video.

We also distributed the Enzyme booklets/notes and discussed the upcoming lab involving Catalase (again, view the video for particulars on it’s work with Hydrogen Peroxide).

 

Science 8 – your Halloween dissections have been delayed by a block. They’re still happening but after Halloween.

Biology 12 – We will be looking into some of the most prevalent disorders of the Cell Membrane including but not limited to, Cystic Fibrosis, Alzheimer’s, and Hyaline Membrane Disease.

Hyaline Membrane Disease - a disease of preterm infants in which the lungs 
are not fully mature at the time of birth, resulting in respiratory 
distress. Pneumocytes are not fully differentiated and so the lungs are 
not capable of the normal oxygen/carbon dioxide exchange that is required 
after birth.

Alzheimer's - oxidative stress (in the brain) caused by Alzheimer's 
results in alterations in the phosphlipids that comprise the cell membrane 
and disrupts the function of affected brain cells.

Cystic fibrosis - a defect in a calcium-ion channel results (for unclear 
reasons) in excess production of fluid in the lungs.
