Question | Answer |
---|---|
hyperbolic, a characterisitc of many enzymes | What is the shape of the Michaelis Menten Plot? |
Y axis is velocity, X axis is substrate | What does the Michaelis Menten Plot entail? |
proporitonal to some extent | What is the relationship between velocity and concentration? |
The saturation point of the enzyme | What do you call the point where velocity no longer changes based on the concentration of the substrate? |
Vmax | _____ is when velocity reaches its maximum and no longer increases |
Km | ____ is an important characterisitc of enzyme-substrate interactions and is independent of enzyme and substrate concentrations. |
Thermodynamically unfavorable Once you have a product, it can never go back | Why can't E+P turn into ES? |
The reverse reaction (P to S) is unfavorable because the equation describes initial when the concentration of the PRODUCT NEAR ZERO ES complex is a STEADY RATE INTERMEDIATE. Concentration of ES remains relatively constant because it is produced and broken at the same rate. | What are the two assumptions in enzyme reactions? |
Km= (K-1+K2)/k1 | Which of the following formulas is a Michaelis Constant? |
