Explain what causes menkes syndrome include in your answer the symptoms and life expectancy of the affected person
dem82 [27]

Answer:

Menkes disease is caused by a defect in the ATP7A gene. The defect makes it hard for the body to properly distribute (transport) copper throughout the body. As a result, the brain and other parts of the body do not get enough copper, while it builds up in the small intestine and kidneys. Menkes syndrome causes impaired copper absorption. This results in changes in the arteries and deterioration of the brain. Menkes syndrome is rare. Most children born with Menkes syndrome have a life expectancy of < 4 years.

Emzymes optimally work best at
posledela

Answer:

Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration.

Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

Explanation:

Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.

pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.

Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to. Once all of the substrate is bound, the reaction will no longer speed up, since there will be nothing for additional enzymes to bind to.

Substrate concentration: Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

This is for the table at the top

<em>Plentiful roaming space</em>- increase - <u>because they</u><u> have more space they can live in.</u>

<em>Severe</em><em> </em><em>drought</em><em> </em><em>-</em><em> </em>decrease<em>-</em><em> </em><em> </em><u>because they</u><u> </u><u>wont</u><u> </u><u>have</u><u> </u><u>enough</u><u> </u><u>water</u><u> </u>

<em>abundant food </em><em>source</em><em> </em><em>-</em><em> </em>increase - <u>Because they have enough food to sustain themselves </u>

<em>Habitat </em><em>destruction</em><em> </em><em>-</em><em> </em>decrease - <u>Because they won't have a place to live in </u>

<em>Elimination of predators</em><em> </em><em>-</em><em> </em>increase - <u>Because there will be less animals hunting them for food.</u>

<em>Lack of competition</em><em> </em><em>-</em><em> </em>increase - <u>Because they won't have to compete for food which will allow them to have more.</u>

<em>Disease</em><em> </em><em>outbreak</em> - decrease - <u>Because the disease will kill a lot of them and can potentially cause birth rates to go down</u>
