Mаtch the wоrds highlighted in red in the twо pаrаgraphs belоw to the correct terms. Not all terms will be used. ATCase is an allosteric enzyme that catalyzes the first step of pyrimidine formation. This first step involves the transfer of carbamoyl phosphate to the substrate, __________, to form "product A". "Product A" goes on to form (after several additional steps) a pyrimidine-based nucleoside triphosphate such as CTP. Early studies showed that the rate of formation of "product A" decreased as the concentration of the final product, CTP, increased. This is an example of ___________, a mechanism that prevents a pyrimidine surplus. In this scenario, CTP is acting as a ___________ effector of ATCase. At the same time, adenosine triphosphate (ATP), an end product of the parallel purine biosynthetic pathway, can act to ____________ ATCase activity. ATP is acting as a _____________ effector of ATCase. Ultimately, the interplay between CTP, ATP, and ATCase ensures an appropriate balance of purines and pyrimidines within the cell. ATCase is a textbook example of a molecule under allosteric regulation. The initial binding of one or more substrates to one active site in the enzyme results in conformational changes that increase the likelihood that the enzyme will bind more substrate. Furthermore, binding of ATP to an allosteric site of the enzyme also increases the likelihood that the enzyme will bind more substrate. The conformational change of ATCase that occurs following the binding of either substrate or ATP that results in even more substrate binding is an example of a phenomenon called ______________. For this phenomenon to be possible, ATCase must consist of ____________ subunit(s). As the substrate (or ATP) bind to ATCase, more of the enzyme transitions from the ____________ state to the ____________ state. The R ("relaxed") state is a ____________ state, while the T ("tense") state is a _____________ state. These states coexist within a dynamic equilibrium that is sensitive to substrate availability and allosteric regulation.

Whаt is Hаemоphiliа? Haemоphilia is usually an inherited bleeding disоrder in which the blood does not clot properly due to a mutation on the gene that codes for the protein that helps blood to clot. This protein factor is called factor VIII or factor IX. Without this gene, this can lead to spontaneous bleeding as well as bleeding following injuries or surgery. These blood-clotting genes are located on the X chromosome. The X chromosome contains many genes that are not present on the Y chromosome. This means that males only have one copy of most of the genes on the X chromosome, whereas females have 2 copies. Thus, males can have a disease like haemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene. Females can also have haemophilia, but this is much rarer. In such cases both X chromosomes are affected, or one is affected, and the other is missing or inactive. In these females, bleeding symptoms may be similar to males with haemophilia. Haemophilia occurs in about 1 of every 5,000 male births. Based on a recent study that used data collected on patients receiving care in federally funded haemophilia treatment centres during the period 2012-2018, about 20,000 males in the United States are living with the disorder. About one-third of babies who are diagnosed with haemophilia have a new mutation not present in other family members. In these cases, a doctor might check for haemophilia if a new-born is showing certain signs of haemophilia. To make a diagnosis, doctors would perform certain blood tests to show if the blood is clotting properly. If it does not, then they would do clotting factor tests, also called factor assays, to diagnose the cause of the bleeding disorder. These blood tests would show the type of haemophilia and the severity. The best way to treat haemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is done by infusing (administering through a vein) commercially prepared factor concentrates. The pedigree diagram (on your Resources Addendum) shows the possibility of one particular family’s inheritance of haemophilia.
