Enzymes Flashcards
Metabolism
All the chemical reactions in living cells
Enzymes are essential for metabolism meaning
Enzymes are catalysts and control rate of reaction
Protein synthesis anabolic or catabolic
Anabolic
ADP TO ATP anabolic or catabolic
Anabolic
Reactions in which product molecules are larger than substrate molecules
Anabolic
One way enzyme can be denatures
High temperature
Two features of denatured enzyme
Change structure
Loss of function
apart from c h o there is one other element
Nitrogen
What is an enzyme
Biological catalyst
Specificity of an enzyme meaning
Acts on only one particular substrate
How Active site theory may be used to explain specificity of enzymes
Substrate matching enzyme’s active site and active site changes shape
Immobilisation meaning when used about enzymes
Attached to an inert substance
Bioreactor
Vessel in which products are made by cells
One example of immobilised enzymes in bioreactors. Name enzyme substrate and product
Starch, amalase, maltose
Which group of bio molecules
Proteins
Factor that influenced activity
Ph or temp
How you carried out
- Mix sodium Alg and water
- Mix yeast and water
- Dissolve calc chloride in water
- Pour yeast sol into sodium alg and mix and put into syringe
- Mix slowly to beaker of calc chloride
- Leave for 15 mins to harden
How used apparatus
Add sucrose solution to sodium alginate
Test for glucose using test strips
Chemical nature of enzymes
Protein
Shape
Folded
Enzyme used for temp
Catalase
Substrate
Hydrogen peroxide
Why keep ph constant
To eliminate as possible influence on rate
How to keep ph constant
Ph buffer
