Thursday Notes

Designing experiment:

• want to see if the lactose pills work, instead of using drops
• questions:
  
• if you break down lactose, becomes what? glucose and glactose together makes lactose, so thats what it breaks down into
  
• what does it mean to be lactose intolerant? do not have lactase, which breaks down lactose
  
• pH of stomach acid? pH of 1-2
  
• Time is takes?
• temperature needed?
• rate of dissolving?
• inactive ingredients
• how is lactose free milk made?
• glucose level of milk originally?
• amount of enzyme?
• tested water, glucose water, reg. milk, lactose free milk, and reg milk + lactaide (lactase)
• waters showed that strips work, reg milk had no glucose, lactose free had 1000 parts, and after 5 min milk + lactaide had 750 parts which means the lactose in it had been broken down!
• bb's in cd case with PVC pipe simulates enzymes and substrate

SICKLE CELL ANEMIA

• very serious!
• genetically inherited
• shaped like a sickle
• harder to go through capillaries
• SICKLE CELL SCENARIOS
• act out situations where some have sickle cell and ask if they should worry about SCA in their kids
• not sure since sheila could be a carrier or not have it at all
• can do blood test
• use electrophoresis to run the blood -> sickle cells have less of a (-) charge so doesn't travel as far as the regular blood (regular beta globin)
• bag activiyt
• bags are like membrane, nucleus is another bag with DNA in it (paperwith pairs written on it)
• have similaraties and differences
• polar has magnet
• HAVE to find start codon first!!
