Answer:

The reasons why Adenosine Triphosphate is a common energy source for all organisms is that: 1. It is a high-energy molecule 2. ATP has an unstable structure compared to other high-energy molecules. 3. ATP has higher potential to transfer phosphate group.

Explanation:

The transfer of phosphate group from high energy molecule like the adenosine triphosphate (ATP) usually release energy that is required by most of cellular activities, thus this dephosphorylation process is an exergonic reaction. While other molecules like the GTP can give energy, these molecules are more stable structurally and breaking them down will not by energetically wise, thus there is need to use a less stable high energy molecules like the ATP which have the potential of releasing their phosphate radical more easily. This is the reason why all organisms make use of the ATP molecule as the only energy source.

A client is being treated for the ingestion of a neurotoxin that interferes with the depolarization phase of action potentials.

masya89 [10]

Answer:

The inflow of sodium ions.

Explanation:

The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.

The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.

Thus, the answer is inflow of sodium ions.

The exodus of medical professionals from africa to europe is an example of brain drain as it has the potential to __________.

Marat540 [252]

Out of the following given choices;

A) spur economic development in Africa

B) impede economic development in Africa

C) impede economic development in Europe

D) spur economic growth for those medical professionals

The answer is B. Brain drain means a country is losing its professionals to the external market rather than working in the local market due to unfavorable local conditions. The country loses because it has few medical professionals to treat its people hence it carries a higher burden of diseased people. Additionally, to cater to this gap, it has to import these medical services which is more expensive than keeping local talent.

The presence of a negative allosteric effector on an allosteric protein would: a. cause a shift to the left in the sigmoidal cur

Feliz [49]

Answer:

d. raise the apparent value of the equilibrium constant, L.

Explanation:

Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.
