Chapter 4 Enzymes and Energy Flashcards
1
Q
What is the law of mass action
A
An increase in amount of reactants will increase the rate of production
Also…
An increase in the amount of products will decrease the rate of production
2
Q
What is an enzyme
A
A biological catalyst that lowers activation energy in order to speed up the rate of reaction
3
Q
What characteristics of enzymes are there
A
Enzymes are proteins
They usually end in “ase”
Some require activation
Lock and Key model
4
Q
Lock and key model
A
The use of binding sites to bring substrates together
5
Q
What effects enzymes
A
Temperature
pH
Concentration
6
Q
What are the 3 metabolic pathways and where does each occur
A
- Glycolysis - cytosol
- Krebs cycle - matrix
- Oxidation phosphorylation - inner membrane
7
Q
What is ATP known as
A
The universal energy carrier
8
Q
What is saturation
A
When all enzymes are participating fully because there is an abundant amount of substrate
