How do substrate concentration and pH affect enzyme-controlled reactions

Biology
1 answer:
Dima020 [189]4 years ago
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.

Predict which mechanism of reproductive isolation played a role in trumpeter speciation in the Amazon basin. Note: Trumpeters ca
Alexandra [31]

Habitat isolation is likely to be most relevant in the case of trumpeters in the Amazon basin.

If trumpeters can not cross rivers, then they would be able to mate with trumpeters on the same side of the river but not on the other side- a form of prezygotic isolation.

what are trumpeters?

The term "trumpeter" comes from the deep, booming territorial call of these chicken-sized, long-necked, hunch-backed, small-headed, short-tailed, dark-plumed, long-legged birds that wander the jungle floors of South America.The land of South America that now the Amazon River and its tributaries drain is recognized as the Amazon basin.

Why can you catch a cold or flu more than once
Rufina [12.5K]

The flu and the cold are diseases that usually present in mild symptoms, but to be able to say why we can catch them more than once, we need to know that.....

<h3>Flu</h3><h3> </h3>

Influenza, is a viral infection of the respiratory system. It is caused by the Influenza virus, which can be type A or B. It is mainly characterized by a picture of symptoms that leaves the person feeling very down and tired, causing a lot of discomfort.

<h3>Cold</h3>

Cold is and how it differs from the flu. To begin with, it is worth noting that it is also a viral respiratory infection. The difference between a cold and the flu is that it can be caused by other types of viruses, such as the more frequent Rhinovirus and Parainfluenza.

<h3>Can I have the flu or a cold more than once?</h3>

The good news is: no, you can't. The bad news is, there are a lot of viruses and germs flying around this time of year, and instead of catching the same one, you have a high chance of catching another.  

The body's immune system recognizes and fights off germs, such as viruses that have invaded your blood, the viruses that cause the flu can change each year, so even if you've had the flu recently, it's recommended that you get a vaccine that matches the new viruses that may be circulating each year.  Because the flu is caused by several viruses, the immunity you naturally develop after infection will only protect you against that type, so you can catch it from another one as well.

With this information, we can conclude that, we can have flu and cold more than once, because we will be in contact with many viruses that cause the flu and the cold.

What scientist studied how wounds heal and proposed that cells come from preexisting cells
DochEvi [55]

Answer:

Rudolf Virchow

Explanation:

During his studies on inflammatory exudates, Rudolf Virchow observed that the increased number of cells in the exudates was due to the formation of new cells by pre-existing cells. He also studied that the formation of new cells from the preexisting cells is responsible for wound healing and for normal growth and development of living beings.
