Assessment 2 Flashcards
How do stem cells differ from other cells
They continue dividing by cell division to produce more stem cells
They can differentiate into a wide variety of cell types
Tissue
Cells with the same specialised and function are grouped together eg blood or skin
Organ
A structure made of several types of tissue that carry out a particular function eg heart or liver
Organ System
Organs which operate together to carry out a specific function are linked together eg digestive or respiratory systems
Downside to using stem cells for leukaemia treatment
The stem cells may divide in an uncontrollable way and produce tumours or unwanted cell types
Chemotherapy and radiotherapy may leave the patient with no immune system
Symbol equation for photosynthesis
6CO2 + 6H2O ===> C6H12O6 + 6O2
Optimum
The state were all factors are at perfect levels
Compensation Point
The point at which the rates of photosynthesis and respiration are equal
Simple sugars
Single sugars eg glucose
Complex carbohydrates
Long chains of sugars eg starch
Inhibitors
Molecules that fit loosely into the active site blocking the substrates from entering
