rjkz [21]

Answer:

The correct answer is option - 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

Explanation:

Normally the drug that is provided and administrated to the fetal is through the placenta of the mother. The direct delivery of medicine can be dangerous. However, with the advancement of the medical technology direct fetal drug administration is possible and it assists in the rapid uptake of the drug by the fetus.

If the fetus requires a rapid drug effect it can be provided by direct drug delivery. Also when the placental is not working properly and affected by the disease it is recommended to provide the fetus with the drug with the help of direct delivery.

Thus, the correct answer is : 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

vagabundo [1.1K]
<h2>Correct answer is option "E"</h2>

Explanation:

  • The citric acid cycle, otherwise called the Krebs cycle or tricarboxylic acid (TCA) cycle, is the second phase of cell breath. This cycle is catalyzed by a few compounds and is named to pay tribute to the British researcher Hans Krebs who recognized the arrangement of steps engaged with the citric acid cycle. The usable vitality found in the starches, proteins, and fats we eat is discharged for the most part through the citric acid cycle. Despite the fact that the citric acid cycle doesn't utilize oxygen legitimately, it works just when oxygen is available.  
  • In eukaryotic cells, the citric acid cycle utilizes one particle of acetyl CoA to produce 1 ATP, 3 NADH, 1 FADH2, 2 CO2, and 3 H+. Since two acetyl CoA particles are created from the two pyruvic acid atoms delivered in glycolysis, the complete number of these atoms yielded in the citric acid cycle is multiplied to 2 ATP, 6 NADH, 2 FADH2, 4 CO2, and 6 H+. Two extra NADH atoms are additionally produced in the transformation of pyruvic acid  to acetyl CoA preceding the beginning of the cycle. The NADH and FADH2 atoms delivered in the citric acid cycle are passed along to the last period of cell breath called the electron transport chain. Here NADH and FADH2 experience oxidative phosphorylation to produce more ATP.
  • Hence, the correct answer is option E " The amount of ATP would be reduced from a total of 38 ATP to 14 ATP"
