patients with pyruvate dehydrogenase deficiency show high levels of lactic acid in the blood. however, in some cases, treatment with dichloroacetate (dca) lowers lactic acid levels. dca targets the activity of pyruvate dehydrogenase kinase (pdk). Identify how DCA acts to stimulate pyruvate dehydrogenase activity: a. DCA activates pyruvate dehydrogenase phosphatase b. DCA increases phosphorylotion levels of pyruvate dehydrogenase c. DCA inhibits pyruvate dehydrogenase kinase d. DCA activates pyruvate dehydrogenase kinase
DCA stimulate pyruvate dehydrogenase activity by inhibiting pyruvate dehydrogenase kinase.
Effect of Dichloroacetate on Pyruvate dehydrogenase complex:A metabolic intermediary called pyruvate enters the mitochondria where it is handled predominantly by the Krebs cycle. Pyruvate's structural counterpart is dichloroacetate (DCA). DCA stimulates the pyruvate dehydrogenase complex (PDC), which is responsible for converting pyruvate, alanine, and lactate to acetyl CoA. Since the PDC-catalyzed reaction is a significant rate-limiting step in the aerobic process, it is vital to cellular energetics (Patel and Roche, 1990). DCA inhibits the four known pyruvate dehydrogenase kinase (PDK) isoforms that are known to inhibit PDH, keeping PDH active and unphosphorylated. Reactive oxygen species (ROS), oxidative stress, and ultimately death in the cancer cells are produced as a result of overstimulation of the Krebs cycle in the mitochondria caused by the addition of DCA. Congenital lactic acidosis was successfully treated with the old drug DCA because it inhibits PDK and reduces lactate generation. Studies have shown that the addition of DCA to cancer cells activates the Krebs cycle in the mitochondria, disrupts the cell cycle, and causes apoptosis in many tumors.

The SN1 process' rate-determining step is a unimolecular nucleophilic substitution reaction. It involves a certain kind of organic substitution process. SN1 stands for substitution nucleophilic unimolecular. The rate equation, which states that the SN1 reaction is dependent on the electrophile but not the nucleophile, holds true when the amount of the nucleophile is significantly more than the amount of the carbocation intermediate. This reaction results in the formation of a carbocation intermediate. In general, it happens when strongly acidic or strongly basic conditions are present and secondary or tertiary alcohols react with secondary or tertiary alkyl halides. The SN1 reaction is frequently referred to as the dissociative mechanism in inorganic chemistry. The optimum solvents for this kind of reaction are polar and protic.

I-cell disease is a particularly severe form of lysosomal storage disease. Multiple enzymes are lacking in the lysosome and the organelle becomes stuffed with nondegraded material and therefore generates a so-called inclusion body. I-cell disease is inherited; it is caused by a single gene defect in the N-acetylglucosamine phosphotransferase that is required for the formation of mannose 6-phosphate (M6P) residues on lysosomal enzymes in the cis-Golgi. This enzyme recognizes soluble lysosomal enzymes as a class and hence a defect in this protein affects the targeting of a large number of proteins. What other defect(s) would cause the same phenotype? (Select all correct answers may be more than one)
A) a defect in clathrin function
B) a defect in the mannose 6-phosphate receptor
C) a defect in the phosphodiesterase that removes the GlcNAc group that initially covers the phosphate group on mannose 6-phosphate.
D) a defect in KDEL receptor
Cellular organelles called lysosomes contain a range of enzymes that break down materials. These enzymes are guided to lysosomes by the protein N-acetylglucosamine-1-phosphotransferase (GNPT).
Hydrolytic enzymes are delivered to lysosomes via the mannose-6-phosphate (M6P) route. These hydrolases are initially marked with M6P by N-acetylglucosamine-1-phosphotransferase (GNPT), which catalyzes the diverting of them to lysosomes when it binds to receptors in the Golgi.
The transfer of hydrolytic enzymes to lysosomes occurs via the mannose-6-phosphate (M6P) route. These hydrolases are first tagged with M6P by N-acetylglucosamine-1-phosphotransferase (GNPT), which is then detected by receptors in the Golgi and directs them to lysosomes.
The uridine diphosphate-N-acetylglucosamine can bind in a deep cavity in the catalytic domain, and the nearby residues suggest a one-step transfer process. The GNPT gamma subunit's isolated structure suggests that it may attach to mannose-containing glycans in various configurations, indicating that it may be involved in guiding glycans into the right place.

what would be the most likely effect of mutating the consensus sequence found at the 5' splice site of an intron?
Where the mutation at the 5' splice site is found a longer-than-normal mRNA would be produced in the splicing process. Thus the correct answer is option (C).
The two steps prior to splicing in the processing of mRNA are polyadenylation and 5' capping. Exons and non-coding regions are both present in an mRNA transcript, which is the product of transcription. Splicing entails the exons being rejoined after the introns have been removed from the mRNA sequence (by spliceosomes).
The final transcript will have both protein-coding and non-coding portions if the spot where the splicing process should take place is altered and splicing does not occur. This is because the introns will not be eliminated from the mRNA sequence.
The non-spliced mRNA will be translated into an inactive protein molecule if translation (the creation of protein) ultimately takes place.
This is so that the coding sequences' reading frame won't be hampered by the non-coding sequences.
The complete question is:
What would be the most likely effect of mutating the consensus sequence found at the 5' splice site of an intron?
(A). A shorter than-normal protein would be produced.

What is a basilar membrane?
The basilar membrane is the inner ear's primary mechanical component. Over its length, it has graded mass and stiffness characteristics, and its vibration patterns separate incoming sound into its component frequencies, which trigger various cochlear areas. Sites close to the stapes are vibrated by high frequencies, while the cochlear apex is vibrated by low frequencies. Similar to the notes on a piano, the pattern of frequency in cochlear space is roughly logarithmic.

What is the most likely result of Independent Assortment?Mendel's law of independent assortment states that genes do not interact with one another when it comes to the selection of alleles into gametes: every conceivable allele combination for every gene has an equal likelihood of occurring.
New allele combinations are created independently of one another.
In meiosis I, chromosome sets with novel allele combinations are produced by crossing over during prophase and independent assortment during anaphase. Randomly fertilizing the gametes created by meiosis also contributes to genetic variation.

Cytotoxic T cells are primarily responsible for cell-mediated immunity.
What are cytotoxic t-cells ?There are mainly two types of T cells: helper T cells and cytotoxic T cells. As the name indicates, helper T cells “help” other cells of the immune system, whereas cytotoxic T cells kill virus-infected cells and tumors. Cytotoxic T cells have so-called CD8 receptors on their surface. The CD8 receptor interacts with cells called major-histocompatibility-complex (MHC) class I molecules to recognize the infected cells. Recognition of infected cells by CD8 receptors activates cytotoxic T cells. Once activated, T cells undergo clonal expansion and differentiation, followed by stages of contraction when pathogens are cleared. Cell survival and cell death are important to control the numbers of naive, effector, and memory T cells.
Cytotoxic T cells kill targets by programming apoptosis. When cytotoxic T cells are mixed with target cells and brought into rapid contact by centrifugation, antigen-specific target cells can be programmed to die within five minutes of her, but not before death is fully apparent. may take several hours.

Which 3 processes result in the release of carbon?.
Carbon is returned to the atmosphere in a number of ways, including when animals perish, volcanoes erupt, fires burn, fossil fuels are burned, and through a number of other processes.
When organisms breathe or decay, weathering of carbonate rocks, forest fires, and volcanic eruptions all take place naturally, carbon dioxide is released into the atmosphere. Human activities like the burning of fossil fuels, clearing forests, and making cement all contribute to the atmosphere's increase in carbon dioxide. Burning hydrocarbon fuels, such as wood, coal, natural gas, gasoline, and oil, releases carbon dioxide into the atmosphere. Carbon from fossil fuels reacts with oxygen in the air to produce carbon dioxide and water vapor during combustion. Carbon is released into the atmosphere by living things. Carbon dioxide (CO2) is a gas that is released into the atmosphere each time you exhale. Through a process known as respiration, both plants and animals must get rid of carbon dioxide gas.
