A class of rodenticides (commonly referred to as rat poison) work by antagonizing Vitamin K. If a child or animal ingests these rodenticides, would you expect to see normal clotting time, prolonged clotting time, or faster clotting time? Explain.

Expert Solution

There will be Prolonged clotting time-

Explanation-Rodenticides are the substances that are used to kill rat.Usually they are mixed with foods that are attractive to Rodents like cheese.So there is a possibility that it may be aten by small childrens accidentally.

There are different types of Rodenticides that differ in their mechanism of action.

Some of them wotk by antagonising Vitamin K-

They irreversibly bind to enzyme vitamin K 2,3‐epoxide reductase---------which causes interruption in the recycling of vitamin K-------Reduction in the amount of Vitamin K.

Vitamin K is an important cofactor for the carboxylase which catalyzes the carboxylation of glutamic acid residues present on the vitamin K-dependent proteins like factors II(Prothrombin), VII, IX, X.

These factors are essentail for the formation of clot through the coagulation cascade--Deficiency of these factors leads to Prolonged clotting time

Billy was slipped a poison. This particular poison slows down the Na-K solute pump of neurons. If the solute pump slows down, what will happen to the neurons? Will the neurons become more excitable or less excitable or would it have no effect on depolarization potential?

Vitamin K is involved in normal blood clotting. When 1.93 g of vitamin K is dissolved in 25.0 g of camphor, the freezing point of the solution is lowered by 6.47 °C. The freezing point and Kf constant for camphor can be found here. Calculate the molar mass of vitamin K.

Vitamin K is involved in normal blood clotting. When 1.91 g of vitamin K is dissolved in 25.0 g of camphor, the freezing point of the solution is lowered by 6.40 °C. The freezing point and Kf constant for camphor can be found here. Calculate the molar mass of vitamin K.

vitamin K is necessary for the absorption of vitamin B 12 from the intestines

Ethanol is commonly referred to simply as alcohol or spirits, It is the principal type of alcohol found in alcoholic beverages. It is a psychoactive drug and one of the oldest recreational drugs used by humans. It can cause alcohol intoxication when consumed in sufficient quantity. It is a volatile, flammable, colorless liquid with the structural formula CH3CH2OH. The density of an aqueous solution containing 45 weight percent ethanol is 0.92472 g/mL. a) A person weighing 75 kg takes a...

The intensity of sound follows a pattern commonly referred to as an Inverse Square Law as supported by the intensity equation for a spherically uniform radiation. Explain what this means using examples of changing distance such as doubling, tripling and halving the distance, and what that does to the intensity. Describe in detail one other physical phenomena that obeys an inverse square law.

May 4th is commonly referred to as “Star Wars” day due to the statement of “May the Fourth be with you” and its aural similarity to “May the force be with you.” Within the Star Wars franchise, those who are imbued with the ability to manipulate the force can, after time, manipulate their physiology to reduce their breathing rate and induce bradycardia (reduced heart rate). This can be explained by specialized molecules called “midichlorians” controlling the autonomic nervous system. Assuming...
