A patient is being treated with carbonic anhydrase (CA) inhibitor. Which of the ions will be affected and what will be the effects on urine/plasma pH and urine volume?

Answers

Answer:

bicarbonate ions; urine alkalinization; carbonic anhydrase inhibitors increase urine volume (diuretics drugs)

Explanation:

Carbonic anhydrase inhibitors are diuretic drugs that have been primarily used to treat glaucoma, a condition where the optic nerve is progressively damaged due to an increased pressure in the eye. Carbonic anhydrase inhibitors reduce the production of aqueous humor in the eyes by decreasing bicarbonate (HCO3-) production, thereby also reducing the intraocular pressure, which is useful to treat glaucoma. Diuretics are drugs that are able to increase the volume of urine by stimulating the excretion of salts and water from the kidneys. In the kidneys, carbonic anhydrase inhibitors inhibit HCO3- uptake by the proximal tubule, leading to urine alkalinization.

What is a gene? Can someone tell me what is Euchromatin? Is Euchromatin also called a Gene? What's the difference between these two?

Answers

Answer:

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.

Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.

The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)

Allosteric effectors: Question 1 options: can lead to a decrease in the availability of a protien alter enzyme activity by binding to the active site of an enzyme can cause large changes in enzymatic activity decrease the sensitivity of the enzyme at nearly all concentrations of substrate do not alter the sensitivity of a metabolic pathway

Answers

Answer:

can cause large changes in enzymatic activity

Explanation:

An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.

An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.

When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Additionally, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Furthermore, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction.

In the human body, the optimal temperature for enzymes is around 37 degrees celsius (°C).

In conclusion, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

As you saw in Part C, the body sizes of sympatric and allopatric P. cinereus and P. hoffmani are consistent with a hypothesis of character displacement resulting from interspecific competition. What additional information would strengthen the argument that character displacement is in fact responsible for body size evolution in these salamanders

Answers

Answer:

Divergence in the body size trait between both species occurred once they were living together. The evolution of the trait difference occurred after sympatry.

Explanation:

Close species, P. cinereus and P. hoffmani, mostly live in different regions. In allopatry, both species have the same -or very similar- body size. Body size in these species is a heritable trait.

However, there are some areas where P. cinereus and P. hoffmani coexist. When they are in sympatry, P. cinereus exhibits a smaller body size and feeds on smaller prey items than allopatric P. cinereus. On the other hand, sympatric P. hoffmani exhibit bigger bodies, feeding on bigger prey items than the allopatric P. hoffmani.

So, when both species are in sympatry, they develop different morphological traits to avoid competition between them and manage to coexist in the same area. Resource availability is limited, so P. cinereus became smaller and feeds on small prey, while P. hoffmani became bigger and feeds on bigger prey. Through this trait divergence, they got to live longer and reproduce more, decreasing interspecific competition and increasing their fitness.

Allopatric species feed on similar prey items and have similar body sizes, reflecting that the divergence occurred after sympatry. If species living in allopatry were places together in the same habitat, they would exhibit strong competition that, over time, would drive to character displacement.

What renal actions does angiotensin II have that are not related to its ability to produce vasoconstriction

Answers

Answer:

Angiotensin II is a main effector of RAS and is produced due to the release of the renin that forms in the kidney, angiotensin in turn stimulates the release of aldosterone from the adrenal cortex.

Angiotensin II serves various roles other than vasoconstriction to maintain blood pressure that are:

1. Autoregulation of GFR

2. Reduction of salt excretion through direct and indirect actions on renal tubular cells,

3. Growth modulation of renal cells - these express AT1 receptors.

Explanation:

Describe the production of an Action Potential in a post-synaptic neuron and its production of an AP in a neuron. Compare the propagation of these AP's (from the trigger zone to the axon terminal) in myelinated and unmyelinated axon.

Answers

Answer and Explanation:

The function of neurons is to transmit nerve impulses. The transmission depends on the unequal distribution of ions in the interior and the exterior of the cell.

The cell interior has many negative ions –anions- and k+ ions that cannot get out of the cell, while the extracellular space has many Na+ and Cl- ions.  

The charge difference between the interior and the cell exterior is named resting potential difference, representing a non-exited state.  

When the neuron is stimulated, many changes in channel proteins occur that let the ions move through the membrane altering the resting-potential difference.

The central nervous system generates an action potential that travels to the target activating the calcium channels. Calcium triggers vesicles fusion to the presynaptic membrane releasing a neurotransmitter into the synaptic space. Once there, the molecule binds to its receptors on the postsynaptic membrane, causing ion channels to open. The activation of different receptors will cause a change in the postsynaptic membrane modifying the cell activity.  

Two types of receptors can be found the in te postsynaptic membrane:

Ion channel receptors -or ionotropic- that produce a fast change in the membrane potential when opening. But when the neurotransmitter disappears, the response does it too.   Metabotropic receptors that trigger a slow change in the membrane potential. They produce a slower response, but it lasts longer.  

Depending on the ion flow through the membrane channel receptors, the postsynaptic potential may be depolarizing - excitatory postsynaptic potential, EPP-, or hyperpolarizing - inhibitory postsynaptic potential, IPP-. For instance, the entrance of Na+ ion depolarizes de cell. But if K+ gets out of the cell, it produces hyperpolarization.  

Depolarizations or hyperpolarizations can be taken to other regions of the cell. The depolarizing or hyperpolarizing effect will gradually fade as it increases the distance from the potential change origin.  

Under physiological conditions, when the axon is stimulated occurs a depolarization. If the stimulus exceeds a threshold level, many sodium gates open simultaneously, and the action potential occurs, responsible for the nerve impulse transmission. Once Na+ channels get closed, K+ channels open. Ions traffic consists of the pass of sodium to the interior of the cell and potassium to the exterior. K+ follows a concentration gradient, while Na+ follows an electrochemical gradient.  

When the electrical stimulus is applied to the membrane of the axon it produces depolarization by activating the sodium voltage-dependent channels all along the axon. Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.  

There is a directly proportional relationship between the fiber diameter and the conduction velocity. The greater the diameter is, the faster the conduction is. Most axons contain a myelin sheath formed by the envelopment of the axon by glial cells. Myelin is fatty and isolates the axon, so in myelinic regions, there is no ion exchange. So to conduct the impulse, there must be regions without myelin. These regions are the Ranvier nodes, which have channels for ion interchange.  

The conduction speed increases in myelinated fibers because of the high concentrations of sodium channels in the Ranvier nodes. Mielinized fibers are thick, and their conduction velocities are very fast.
