Answer:

B) cAMP

Explanation:

Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are  are regulators of signal transduction: regulate the duration of signaling pathway.

Caffeine is  central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.

The usage of EHR can enable the training to adjust all the more effectively to the new framework, which will provide profit for patients, doctors and staff.

Explanation:

In the initiation process EHR includes a multidisciplinary way to deal with set up the new framework, guarantee protection and security consistence, plan rehearse work process and also they deal with appropriation procedure.

There are nine steps for successful implementation of EHR they are Create an implementation team, Configure the software, Transfer  data, Providing the physician liaison ROI, Driving referrals through physician preference.

The skills are needed in health information technology with the expanding usage of electronic well being records and the utilization of illness .

In the event the training is recorded as paper based and the longitudinal record is an essential idea for the training member.

The advantages and disadvantages of using this software analyzing chart is the utilization of subjective information examination programming incorporate being liberated from manual and administrative errands, sparing time and having the capacity to manage a lot of subjective information.

Thus the analysts have methodological ways to deal with utilizing subjective information investigation programming as they could fit between research strategies and structure.

A team of biologists develop a new drug, and one team member hypothesizes that the drug is incapable of freely passing across th
matrenka [14]

Answer:

<em>B: The drug is a small charged molecule</em>

Explanation:

Substances can passively diffuse in and out of the cell via the cell membrane in two ways;

  • Simple diffusion
  • Facilitated diffusion

The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.

In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.

Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.

<em>Correct option: B</em>

Feliz [49]

Answer:

-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid

Explanation:

During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.

The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.

As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.
