How do substrate concentration and pH affect enzyme-controlled reactions

1 answer:

6 0

For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.

Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.

In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.

Viruses _____.

Montano1993 [528]

viruses are tiny bundles of genetic material which is carried in a viral coat.

<u>Explanation:</u>

The virus is generally a parasite that needs a host to become active and to reproduce. It cannot reproduce without the host.
The tiny bundle consists of genetic material and protein. The virus consists of capsid and nucleic acid. This capsid is said to be the protein coat.
This capsid consists of either RNA or DNA. virus replicate themself within the host body by using its genetic material along with the mechanism of the host.
Thus after replicating the virus need to get out of host cell, It is performed by two types budding or lysis( bursting the host cell ).

Which of these finding suggests a serious illness from a urinalysis?

Roman55 [17]

Although there should be choices in this question, many findings in the urinalysis can point out a serious illness as long as it is clinically correlated. The color of the urine such as tea-colored urine may be a sign of obstruction of the biliary tree such that in choledocholithases or stones in the common bile duct. The consistency of the urine such as when it is hazy may indicate infection or albuminuria. Sugars present in the urine may indicate diabetes mellitus. Increased WBC (or pus cells) and RBC in the urine may point to a urinary tract infection (pyelonephritis) or glomerulonephritis. A positive protein in the urine may indicate albuminuria characteristic of nephrotic syndrome.
