in a signal transduction pathway, activated g proteins can then activate which of the following enzymes?

Answers

Answer 1

One of the common targets of activated g proteins is adenylyl cyclase.

Adenylyl cyclase, a membrane-associated enzyme that is activated by the GTP-bound alpha subunit, catalyzes the creation of the second messenger cAMP from molecules of ATP, is one target of activated G proteins that is very frequently found.

Many extracellular signals are detected by G Protein Coupled Receptors (GPCRs), which then transmit those signals to heterotrimeric G proteins. These G proteins then transmit those signals intracellularly to the proper downstream effectors, playing a crucial part in a number of signaling cascades.

G protein-coupled receptors (GPCRs) are integral membrane proteins that let cells respond to external signals such as hormones and neurotransmitters as well as signals from the senses of sight, smell, and taste.

A sample of milk is tested for its bacterial content in a plate count assay. A one-milliliter sample of the milk is diluted in a 1:10 dilution series. One milliliter of the third dilution tube is plated in a pour plate. After incubation, the plate has 54 colonies, indicating that the original milk sample contained how many CFU/ml?

Answers

After incubation, the plate has 54 colonies, indicating that the original Milk sample contained 540,000 CFU/ml.

The equation for calculating the CFU/mL in the original sample is:

CFU/mL = (number of colonies on plate x dilution factor) / volume of the culture plated

Here,

Number of colonies on plate = 54

Volume of the culture plated = 1 mL

The original sample is serially diluted in a proportion of 1:10, that is 1/10

So the dilution of first tube = 1/10

From the first tube, the culture in again diluted in a proportion of 1:10

So, Dilution of second tube = 1/10

The total dilution of tube 2 will be the product of the dilution of tube 1 and tube 2.

So, total dilution of tube 2 = 1/10 x 1/10 = 1/100

Similarly, the total dilution of tube 3 will be 1/1000 and tube 4 will be 1/10000

The sample is plated from tube 4, and therefore the total dilution of tube 4 is used for the calculation of bacterial concentration.

Dilution factor = Reciprocal of dilution

So, dilution factor of tube 4 = 10000 = 104

Substitute the values in the equation:

CFU/mL = ( 54 x 104) / 1 = 54 x 104 = 540000 cells/mL

Answers

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.

Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.

The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.

Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.

Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

People who are lactose intolerant can often consume some products made from milk such as cheese and yogurt because microorganisms in their digestive system consume the lactose. By comparison, people with a true milk allergy, which involves an immune response to milk protein, cannot consume milk or products made from milk. Given this information, what can you conclude about milk?

Answers

Answer:

The enzyme that is responsible for assimilating lactose is the enzyme called lactase, which our body manufactures in the first years of life, after this, if we continue to ingest milk (either bovine or human) this enzyme will be forced to continue to be synthesized, and this is how an enzymatic adaptation occurs over time.

Some people cannot comply with this adaptation and this leads to autoimmune problems when it comes to ingesting dairy products and their derivatives to varying degrees.

Explanation:

On the other hand, the immune response can be more or less harmful according to the genetic predisposition of the person, there are people who have an immunological genetic code oriented to rheumatological failure, and it is there that they do not tolerate any derivative of lactose, and they can even present autoimmune diseases parallel to this problem.

The immunological response to lactose is because it is considered an intestinal antigen, which is due to the absence of metabolism as its own since the person cannot adapt and continue to encode the lactase enzyme throughout their life.

This immune response can even generate an immune infiltrate in the connective tissue walls juxtaposed to the intestinal mucosa.

(iv) Ions get trapped by electrodes.

What is 241 Am smoke detectors?

Because it detects a wide variety of fire situations, Americium 241 is utilized in smoke detectors. They are also less costly and simpler to install than photoelectric lights.

Americium emits an alpha - particle with a 0.9 micro-Curie value. In the detector's ionization chamber, these alpha particles hit with oxygen and nitrogen in the air to produce charged particles, or ions.

A low level voltage placed across the chamber collects these ions. A modest continuous electric current runs between two electrodes when the ions are collected.

If smoke reaches the detector, smoke particles will bind to the ions generated by the alpha particles and oxygen or nitrogen. As fewer ions arrive at their target, the electric current decreases, triggering the alarm.

Hence, the use of 241am smoke detector

Sea anemones are predatory invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish is immune to the sting of the sea anemone and actually lives among its tentacles. The relationship is mutually beneficial—the clownfish often lures meat-eating animals over to the anemone, and the anemone benefits from the meal. The clownfish often gets to eat leftovers from the anemone’s meal.

When the clown fish is ready to lay eggs, it lays them near a sea anemone. How’s this a reproductive strategy?

Answers

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.
