4.nucleic acids
5.polyphosphates




Active transport is the process of movement of a fluid from an area of lesser concentration (Hypotonic), to an area of greater concentration (Hypertonic). This process requires energy and enzymes; a specific molecule called "carrier molecule" binds with each ion to be transported into or out of the cell against the concentration gradient Active transport is the mediated process of moving molecules and other substances across membranes.When particles are being moved from areas of low concentration to areas of high concentration(ie. against the concentration gradient) then specific carrier proteins in the membrane are required to move these particles. The carrier proteins bind to specific molecules (eg. glucose) and transport them into the cell where they are released. Energy is required for this process so this is known as Active Transport.

So the answer is carbs (3)

Hope this helps. If wrong please correct me!!

Formation of enamel and dentin requires adequate amounts of all these vitamins EXCEPT

1. A
2. C
3. D
4. E


pLEASE explain teh answers.

Hi 🙂

The answer is 4 (E)

VitA is required for the maintenance of epithelial tissue and Enamel develops from ectodermal , and epithelial origin.

VitC is required for development of Dentin. Dentin develops from mescenchymal tissue, connective tissue origin (collagen). VitC deficiency will affect the dentin more, due to the role of VitC in collagen synthesis.

VitD supplies calcium, for the normal production of sound dentin and enamel.


Hope this helps u🙂

If teh pH becomes lower than the isoelectric point of a protein,then hwo will teh protein respond in an electrophoretic system. It will,

1. become denatured
2. migrate to negative pole
3. migrate to positive pole
4. remain stationary and unchanged
5. separate into its different monomeric forms


Hi

The answer is 2( will migrate to negative pole)

Explaination: The pH of an electrophoretic gel is determined by the buffer used for that gel. If the pH of the buffer is above the pI(isoelectric point) of the protein being run, the protein will migrate to the positive pole (negative charge is attracted to a positive pole). If the pH of the buffer is below the pI of the protein being run, the protein will migrate to the negative pole of the gel (positive charge is attracted to the negative pole). If the protein is run with a buffer pH that is equal to the pI, it will not migrate at all. This is also true for individual amino acids.

Hope this helps u.

what i was thinkin gwas that the pH is lower than isoel point of proteins so it will dissociate and try to raise the pH and if it dissociates it will have a negative charge due to CONH- so it will move to the positive side....i am confused at this one

 

[njsmahal]

Hi,

Each of the following polymers is correctly paired with its component precursor EXCEPT one. Which si teh Exception?
POLYMER COMPONENT
1. Dextran Sucrose
2. Glycogen Fructose
3. Mutan Sucrose
4. Glycogen UDP - glucose
5. Levan Sucrose

Correct answer is 2. Glycogen fructose

Explanation: Glycogen if a homopolymer of glucose. other combinations like in aswers 1,3,4,5 are correct

1. Dextran Sucrose - homopolymer of glucose formed from hydrolysis of sucrose.
2. Glycogen Fructose-homopolymer of glucose linked by alpha-1,4glycosidic bonds.
3. Mutan Sucrose - homopolymer of fructose formed from hydrolysis of sucrose.
4. Glycogen UDP - glucose- see last step of glycogen synthesis.
5. Levan Sucrose - homopolymer of glucose formed from hydrolysis of sucrose.

-Roni.

glycogen can also be formed from fructose by first converting fructose into glucose but there is no such sugar as mutan...
so answer should be 3

Hey iam not ver sure of this but I think the answer should be 1(sterility)

Advers effect of anabolic steroid: Development of breast tissue in males, a condition called gynecomastia (which is usually caused by high levels of circulating estrogen), may arise because of increased conversion of testosterone to estrogen by the enzyme aromatase. Reduced sexual function and temporary infertility can also occur in males. Another male-specific side effect which can occur is testicular atrophy, caused by the suppression of natural testosterone levels, which inhibits production of sperm (most of the mass of the testes is developing sperm). This side effect is temporary: the size of the testicles usually returns to normal within a few weeks of discontinuing anabolic steroid use as normal production of sperm resumes. Female-specific side effects include increases in body hair, deepening of the voice, enlarged clitoris, and temporary decreases in menstrual cycles. When taken during pregnancy, anabolic steroids can affect fetal development by causing the development of male features in the female fetus and female features in the male fetus.

so testosterone becomes low nd if it doesnt come to the normal levels there would be testicular atrophy... so nothing as a rule but testosterone levels to go down is a rule so we go with that

oh shoot... see a little bit of carelessness can kill lol. ya then the answer seems to be b . i dont know coz sterility can happen in extreme cases but the FSH levels would be high in withdrawl and secondly is that FSH is a glycoprotein so it shouldnt be affected by teh steroid intake... as long as steroid is in the body the levels are normal and when steroid is gone then levels shoot up

Yeah....
Low FSH levels

Diminished secretion of FSH can result in failure of gonadal function (hypogonadism). This condition is typically manifest in males as failure in production of normal numbers of sperm. In females, cessation of reproductive cycles is commonly observed. Conditions with very low FSH secretions are:

1. Hypothalamic suppression
2. Hypopituitarism
3. Hyperprolactinemia
4. Gonadotropin deficiency
5. Gonadal suppression therapy
   1. GnRH antagonist
   2. GnRH agonist (downregulation).

Please do explain me if i am WRONG!!

OR

Why shouldn't the answer be 4 ( decreased number of spermatids)?

Very confusing Question!!

 

[njsmahal]

see now lets review the choices and try to see from that. steroid hormones when we give them body stops using its own glands to produce it and hence there is atrophy of the glands. now that the gland size has decreased we stop giving the steroids. so what will happen. 1. body wants the hormone so it releases releasing or stimulating hormones. so in this case FSH would increase.
2. level of FSH is low so there would be decresed amount of spermatogonia
3. gland has hypotrophy so there would be less testosterone produced
4 in extreme cases there can be complete atrophy of the gland causing sterility if the steroid admin is long term and sudden withdrawl.

now the only thing thats against the choices is decreased levels of FSH instead of this there is an increase of FSH when there is steroid withdrawl

i hope its a little more clear now

hi can u pls. explain concept again , i cant get it.
u said that FSH level will increase but at same time at point no. 2 u acknowledged that level of FSH is low which cause spermatogonia.
3. gland has hypertophy and 4. gland has atrophy on long term use
this is confusing , can u please explain.

Actually what i know is FSH and testosterone both enhance spermatogenesis . so decrease in their level will decrease spermatogenesis also.
But i cant locate correct answer. help me

FSH enhances spermatogenesis by stimulating the follicles. right?
now when is FSH released? when we need testosterone right???
now if we have steroid hormones in the blood. it will tell the brain that we are totally packed so cancel the next order. so FSH doesnt release that much anymore. right?

now FSH doesnt release so there would be hypotrophy or atrophy on long term use.

now next scenario is when we stop taking steroids. thats what the question is dealing wiht.

so FSH was low. and there would be less amount of testosterone in the body. when we stop taking steroids think of it as walmart which doesnt have that much milk anymore. so walmart will call for extra milk (testosterone) so there would stimulation of Pituitary so that more FSH is released so that testosterone can be generated. so right after withdrawl there would be decreased amount of testosterone but at the same time because of that there owuld be increased amount of FSH.... dude i am exhausted i hope it is clear now

and second point was when we were taking steroids thats why it was low.
