Oxygen will be an example of one substance which will diffuse through the capillary wall into the tissue fluid and the cells,Carbon dioxide is another example of a substance as that diffuses from the cells into the tissue fluid then across the capillary walls into blood plasma

Carbon dioxide and oxygen however glucose can be known as another substance too

Which one of the following statements is true of enzyme catalysts? A) Their catalytic activity is independent of pH. B) They are

muminat

Answer:

D) They can increase the reaction rate for a given reaction by a thousand-fold or more.

Explanation:

Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?

trapecia [35]

Answer:

Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).

Explanation:

Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.

The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.

The other options are not correct because:

B. Master genes do not determine the organization of the genome .

C. Regulation of cell metabolism depends of substances as hormones and enzymes.

D. The rate of translation does not depend on the activity of master genes.
