Enzymes Flashcards
What are do enzymes do to reactions
Catalyse them
Are enzymes globular or fibrous proteins
Globular
What is meant by the specificity of enzymes
Which biochemical reaction is catalysed by the enzyme
What are anabolic reactions
Where smaller molecules are joined together to make a larger one
What are catabolic reactions
Where larger molecules are broken down to form smaller ones
Which out of anabolic and catabolic reactions are catalysed by enzymes
Both
What is metabolism
Metabolism is the sum of all of the different reactions and reaction pathways happening in a cell or an organism, and it can only happen as a result of the control and order imposed by enzymes
What factors affect reaction rate
Temperature
Pressure
pH
What is Vmax of a reaction
The maximum rate of reaction
What is activation energy
The minimum amount of energy required for a reaction to occur
What are the 2 ways that enzymes reduce the required activation energy
Lock and key hypothesis
Induced-fit hypothesis
What is formed when enzymes and substrates join together
An enzyme-substrate complex
What do intracellular enzymes do
