In the citric acid cycle when an aldol addition occurs in a biological system, how do the amino acids contained in the Citrate Synthase enzyme help facilitate the reaction

Answers

Answer:

Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate

Explanation:

Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.

If an organism has a diploid number of 54, how many chromosomes will be in each of its gametes?
a. 54
b. 52
c. 27
d. 104
e. 108

Answers

The answer to this question is D

There will be 27 chromosomes in each of its gametes.

Meiosis is also called reductional division, in the process s-ex cells, that is, sperm and egg are produced, and each cell has the half number of chromosomes than its parent cells.

• In the given case, the organism is diploid with 54 chromosomes, that is, 2n = 54.

• Here n is the haploid number of chromosomes, in the given case, n = 27, that is, the haploid number of chromosomes is 27.

• Therefore, the sperm and egg cells have 27 number of chromosomes each.

Thus, the correct answer is option c, that is, 27.

The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop

Answers

Answer:

Negative feedback.

Explanation:

The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain

Answers

Answer:

An antisense sequence with complementary to the target mRNA encoded by the gene of interest

Explanation:

An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.

Answer: 3. anticodon, 4. amino acid, 5. In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. 6. The process of gene expression involves two main stages: Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule. 7. 64. 8. One codon, AUG, specifies the amino acid methionine and also acts as a start codon to signal the start of protein construction. There are three more codons that do not specify amino acids. These stop codons, UAA, UAG, and UGA, tell the cell when a polypeptide is complete. 9. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released. plzz mark brainliest

Answer:

253.585 square inches

Explanation:

The figure can be decomposed into 2 rectangles and a quarter circle.

Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)

✔️Area of rectangle 1 = Length × width

Length = 10 in

Width = 6 in

Area of rectangle 1 = 10*6 = 60 in²

✔️Area of rectangle 2 = Length × width

Length = 10 in

Width = 6 + 7 = 13 in

Area of rectangle 2 = 10*13 = 130 in²

✔️Area of ¼(circle) = ¼(πr²)

r = 9 in

π = 3.14

Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²

✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches

How did a famous event change the course of the American Revolutionary War? in essay form pls

Answers

Answer:

The American Revolution was a political battle that took place between 1765 and 1783 during which colonists in the Thirteen American Colonies rejected the British monarchy and aristocracy, overthrew the authority of Great Britain, and founded the United States of America. See the fact file below for more information and American Revolution facts.

-The American Revolution, also known as the Revolutionary War, began in 1775.

-They wanted England to have no control over them.

-For ten years before the war actually started, there was a lot of tension between England and the colonies.

-The colonies had no central government at the beginning of the war, so delegates from all the colonies were sent to form the first Continental Congress.

-George Washington, a former military officer and wealthy Virginian, was appointed Commander in Chief of the Continental Army.

-Members of the Continental Congress wrote a letter to King George of England outlining their complaints and declaring their independence from England.

which of the following events does not occur in spermatogenesis ​

Answers

Answer:

The mitochondria and Golgi apparatus are packaged into the head of the sperm.

Explanation:

Spermatogenesis is the production of male germ cells. Sufficient stimulation with sex hormones, especially testosterone, and a lower temperature, which is achieved by placing the testicles in the scrotum, are required for the correct course of spermatogenesis. Sperm production has three phases: reproductive, growth and maturation. At the beginning of sperm development are spermatogonia, which are male primordial cells. They have a spherical shape and are located at the edges of the seminal canals. Spermatogonia is mitotically divided. On the one hand, in order to preserve their numbers, and on the other hand, their division produces primary spermatocytes, which lie above the layer of spermatogonia. Primary spermatocytes are diploid, but after the first meiotic division, haploid secondary spermatocytes are formed from them. They still have double chromatids, so a second meiotic division soon occurs, the product of which is spermatids. Spermatids are already fully haploid and do not divide further. Spermatids then undergo a process of spermiogenesis, in which the nucleus condenses, forming a flagellum and losing most of the cytoplasm and some organelles. Immature sperm travel through the seed-forming canals to the epididymis, where they are definitively matured. This whole process takes about 72 days.
