How does the cell regulate the substrate specificity of ribonucleotide reductase to maintain equal amounts of all four deoxynucl

eoside triphosphates (dNTPs)? Choose one or more: A. When dTTP is bound to the specificity site, more dCDP is produced. B. When dGTP is bound to the specificity site, more dUDP is produced. C. When dTTP is bound to the specificity site, more dGDP is produced. D. When dGTP is bound to the specificity site, more dADP is produced.

Answer:

The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced

Explanation:

Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.

                  When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.

               Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.

        Thus equal amount of deoxyribonucleoside triphosphates  are maitained by the cell.

How did the “Father of Anatomy” contribute to the study of the human body?
anastassius [24]

Answer:

Andreas Vesalius became first to study human anatomy.

Explanation:

Andreas Vesalius wrote a book called Seven Chapters on the Structure of the Human Body that caused to the rise of advanced human anatomy. His work became very notable for medicine because it gave physicians a thorough knowledge of human anatomy, and it propelled them to examine the claims of ancient medical experts, which were unusual than Vesalius hypotheses. He's seen as a Renaissance figure of the 16th Century and considered being the father of modern medicine.

In a person with a disease in which the mitochondria do not produce enough energy for the cell, which organs would be the most s
erastova [34]

The heart would be one of the most affected organs if the mitochondria do not produce enough energy, since this organ requires a lot of energy, so any supply failure leads to heart failure and contraction failure.

<h3>What are mitochondria?</h3>

They are the cellular structures responsible for supplying most of the energy necessary for cellular activity.

<h3>Characteristics of mitochondria</h3>

  • They produce energy from the metabolism of organic fuels such as sugars, lipids (fatty acids) and amino acids.

  • Insufficient energy production by the mitochondria causes dilated cardiomyopathy, where the heart undergoes significant dilation and loses the force of contraction.

Therefore, we can conclude that a defect in a mitochondrial process involved in energy production would affect heart cells causing dilated cardiomyopathy, heart failure.
