Enzymes Flashcards
What shaped protein are enzymes?
Globular
What are enzymes?
Biological catalysts
What do enzymes do?
Break down substrates by colliding with them.
What is the name of the complex that forms between the enzyme & substrate?
ES complex
What affects the rate of reaction?
Temp, concentration, PH, inhibitors
What are enzymes sensitive to?
PH and temp
What do inhibitors do?
Slow/stop enzyme activity
What is activation energy?
The lowest amount of energy needed for a reaction to happen
What is the name of the hypothesis for enzymes where the substrate fits the enzyme exactly?
Lock and key
What is the name of the hypothesis for enzymes where the active site has to adjust around the substrate so that it can be broken down?
Induced fit
What is the word for when the shape of the active site is similar to that of the substrate?
Complementary
