How does ATP enable transport proteins to move ions across a cell membrane?

1 answer:

7 0

The ATP enables the movement of transport proteins to move the ions across a cell membrane by its getting fueled by its hydrolysis

Explanation:

The plasma membrane is a semi permeable membrane that is the movement of molecules across the membrane is constricted. There are 2 types of moment across the plasma membrane one is the active transport and the other is the passive transport. The active transport involves the help of ATP whereas the passive transport does not involve ATP to transport the materials.

The types of cells found in the parathyroid gland are the parathyroid cells (productive glandular cells) and the oxyphil cells.

IRINA_888 [86]

Answer:

false

Explanation:

The parathyroid gland refers to the four small endocrine glands located in the neck region behind the thyroid. It secretes the parathyroid hormone or parathormone which regulates the calcium levels in our bodies. It comprises two types of cells which are:

a. The oxyphil cells appear at the onset of puberty and they have no known functions. They appear pink or orange when stained with hematoxylin and eosin stain.

b. The chief cells are more abundant compared to the oxyphil cells and stain dark purple by the action of hematoxylin and eosin stain. Their major function is to produce parathyroid hormone which regulates the amount of calcium in the body.

The ____________ pressure in the capillaries drives the filtration of water and small molecules from the blood into the ________

Nesterboy [21]

<h2>Lymphatic System</h2>

Explanation:

The Blood pressure in the capillaries drives the filtration of water and small molecules from the blood into the interstitial space of the tissues.
The invulnerable system is the mind boggling assortment of cells and organs that annihilates or kills pathogens that would somehow cause malady or passing.
The lymphatic system, for a great many people, is related with the safe system to such an extent, that the two system are for all intents and purposes undefined.
The lymphatic system is the arrangement of vessels, cells, and organs that conveys abundance liquids to the circulatory system and channels pathogens from the blood.
The growing of lymph hubs during a contamination and the vehicle of lymphocytes by means of the lymphatic vessels are nevertheless two instances of the numerous associations between these basic organ system.
Circulatory strain causes spillage of liquid from the vessels, bringing about the aggregation of liquid in the interstitial space that is, spaces between singular cells in the tissues.
In people, 20 liters of plasma is discharged into the interstitial space of the tissues every day because of slender filtration.
Lymph is the term used to portray interstitial liquid once it has entered the lymphatic system.

ludmilkaskok [199]

Answer:

Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and  Mannitol Salt agar  are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth  is an example of a liquid that supports growth of a variety of organisms.

Explanation:

Growth media are classified based on their composition as:

1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar

2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.

3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms

4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.

5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.

Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.

What type of receptors embedded in the urinary bladder wall initiate the micturition reflex?

sasho [114]

Answer is stretch receptors.

Stretch receptors respond to the distention of muscle wall of the bladder and are neurologically linked to the medulla. Stretch receptors in the bladder signal the parasympathetic nervous system to stimulate muscarine receptors, present in the detrusor muscle, to make him contract. This leads to the expulsion of urine.

Fruit flies have eight pairs of chromosomes. Calculate the genetic possibilities from independent assortment of a zygote made fr

Furkat [3]

Answer:

256

Explanation:

If there are 2 pairs of chromosomes Aa and Bb, there are 4 possibilities for independent assortment of gametes:

A w B, aith with b, A with b and a with B.

If there are 3 pairs of chromosomes Aa, Bb and Cc, there are 8 possibilities:

ABC, abc, ABc, Abc, aBC, aBc, abC, AbC

This corresponds to 2^n, where n= the number of chromosomes.

Therefore, with 8 chromosomes, the possibilities are 2^8 = 256

This is for each parent.
