Enzymes are protein catalysts. What is the role of a catalyst?
Lyrx [107]

Enzymes are proteins catalysts and speed up reactions by lowering the energy needed to start them. Catalysts speed up the reactions in the cells so that they can happen in a fraction of a second, making them happen more quickly. Without catalysts, most cell reactions would not happen even over long periods of time.

What is mutation, effects and patterns of inheritance and data analysis?
larisa [96]

Answer and Explanation:

Mutation:

It is the sudden variation that occurs in the sequence of our DNA either due to factors related to environment or mistakenly. These are inheritable changes in our genes.

Effects:

a. It results in the ability of an organism to adapt to the environmental variations.

b. It can also cause disorders and diseases in an organism.

c. It results in the evolution of organisms.

d. It also results in the variation in an organisms' phenotype.

d. It helps to carry out scientific research.

Patterns of Inheritance:

The inheritance in mutation only occurs when it is in germ cells which leads to the production of gametes and this mutation is known as germ line mutation.

Data analysis:

As only few cells are effected mostly in mutation it can not be detected.

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.
