Naddika [18.5K]

Answer:

A) two examples of environmental factors that may impact salivary peroxidase activity are pH and temperature. All enzymes have an ideal pH range. When the environment has a pH in that specific range, the enzymatic reaction rate will be the fastest. However, when the environment deviates from the pH range, the enzyme's reaction rate will be slower. Furthermore, when the pH is too far off that ideal pH range, then the salivary peroxidase may denature and unravel, due to it being a protein. Another factor is temperature. When temperature is higher, the reaction rate increases. However, when the temperature is lower, the reaction rate decreases. However, when the temperature gets too high, then the enzyme may denature.

B) The effects of defects in the thiocyanate transport channels would be for lactoperoxidase to not be able to function properly, causing defects in the defense against pathogenic microorganisms in the intestinal tract of newborn infants and defects in sterility of the secretions for the respiratory tract.  

In order for lactoperoxidase to function properly, thiocyanate is necessary. Because of this, Therefore, thiocyanate is likely a cofactor, allowing for lactoperoxidase to function.

Because of this, if the thiocyanate transport channels are defective, thiocyanate can likely not reach the lactoperoxidase, and can therefore not bind to it. This defect in the transport channels would mean that thiocyanate cannot carry out its necessary function of activating lactoperoxidase.

A blood vessel ruptures and bleeds between the meningeal dura mater and arachnoid mater. Which of the following describes the lo
emmainna [20.7K]

Answer:

The correct answer is Subarachnoid space.

Explanation:

The cranial meninges are the layers responsible for enveloping the brain and spinal cord. These layers are: dura mater, arachnoid mater, and pia mater.

Based on these layers there are also three cavities: epidural, subdural and subarachnoid.

The subarachnoid cavity it is located between the arachnoid and the pia, and there we find cerebrospinal fluid that exists between the arachnoid and the pia. This is also where the Cerebrospinal fluid continuously flows as well as the main arteries of the brain pass through this space.

When it is crossed by the main arteries, if a blood vessel breaks and bleeds between the hard meningeal mother and the arachnoid, the location of this bleeding would be in Subarachnoid space.
