They are all part of the Carbon cycle
Answer:
Several 2',3'-dideoxy-3'-thiapyrimidine nucleosides were studied for their ability to inhibit hepatitis B virus (HBV) DNA replication in a HBV-transfected cell line (2.2.15). 2',3'-Dideoxy-3'-thiacytidine (SddC) and 5-fluoro-2',3'-dideoxy-3'-thiacytidine(5-FSddC) were found to be the most potent anti-HBV compounds of those examined. Both compounds resulted in nearly complete cessation of viral DNA replication at 0.5 microM, as monitored by the absence of both intracellular episomal and secreted viral DNAs. The HBV-specific RNAs were not reduced at concentrations that completely blocked HBV DNA replication, suggesting that the inhibitory target is HBV DNA synthesis. The antiviral action of SddC and 5-FSddC was reversible. The concentration of SddC and 5-FSddC required to inhibit 50% of 4-day cell growth in culture was 37 microM and more than 200 microM, respectively. Unlike 2',3'-dideoxycytidine, these two compounds do not affect mitochondrial DNA synthesis in cells at concentrations lower than that required to inhibit cell growth. In view of the potent and selective antiviral activity, both SddC and 5-FSddC should be further evaluated for the treatment of human HBV infection.

Answer:
The correct answer is a Inhibit the enzyme and slow the rates of Glycolysis and citric acid cycle.
Explanation:
ATP accumulation result in blocking the activity of the rate limiting enzyme of glycolysis Phosphofructokinase that catalyses the conversion of fructose-6-phosphate to fructose -1,6-bisphosphate .
ATP is an Allosteric inhibitor of Phosphofructokinase enzyme and this enzymatic inhibition decreases the rate of glycolysis and as the rate of glycolysis decreases the rate of TCA cycle is also decreased because TCA cycle depends on glycolytic end product Pyruvate. As glycolysis rate is decreased pyruvate is not formed in a sufficient amount to carry out its conversion to Acetyl CoA and enters into TCA Cycle.
Answer:
C
Explanation:
For standing waves, the areas where the amplitude is zero are referred to as nodes while the areas where the amplitude is at the maximum are known as antinodes.
A standing wave derives its feature primarily from the fact that there are certain points along the medium of transmission that are apparently seeing to be standing still with no displacement whatsoever. At the same time, there exist opposing points to the points of zero displacements. These points have a maximum displacement in both the positive and negative directions. While the former is referred to as nodal points, the latter is known as the antinodal points.
