What is the initial velocity of the reaction catalyzed by the wild-type enzyme when the substrate concentration is 10 mM?
Doss [256]

Answer:

50 micro mol/min

Explanation:

So, we have the following parameters which are going to help us in solving this particular Question or problem;

=> For the wild type enzyme, the value for the Maximum velocity = 100 micromol/min.

=> For the mutant type enzyme, the value for the Maximum velocity = 1 micromol/min.

So, we can determine or calculate the value for the initial velocity for each of the enzyme type by using the formula below;

Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Therefore, for the wild type enzyme; the Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Initial velocity =( 10mM × 100micromol/min) ÷ ( 10mM + 10 mM ) = 50 micro mol/min.

Initial velocity for the wild type enzyme = 50 micro mol/min.

Recognize<br> 4. What landforms are<br> common in a coastal<br> depositional environment?
coldgirl [10]
Depositional processes along coastlines, such as sediment transport, form sandy beaches and create highly complex landforms that experience constant change and movement. Features such as spits, barrier islands, tombolos, and dunes are classic forms in sandy beach environments.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacte
Lapatulllka [165]

Answer:

Changes in genetic makeup occurs with the passage of time.

Explanation:

Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
