Proteins involved in facilitated diffusion arereceptor proteins?

Proteins involved in facilitated diffusion are typically carrier proteins or channel proteins. These proteins help transport specific molecules across the cell membrane by binding to them and facilitating their movement down a concentration gradient. Receptor proteins, on the other hand, are involved in cell signaling and response to extracellular stimuli.

Is there a paternity test developed when in the early stages of pregnancy and if yes then what is the procedure involved?

Yes, there is a new non-invasive Pre-Natal paternity test which is performed as early as 13 weeks into the pregnancy. This new fetal cell DNA test uses the mother's blood to isolate the DNA of the fetus and then compares it to the alleged father's DNA collected from a buccal swab, hair sample or even forensic samples such as a toothbrush, water bottle or chewing gum - no blood sample is required for the would-be Dad.

Is FSH steroid or hormone?

First off, steroids and hormones are not mutually exclusive groups. The term "steroid" reflect a molecule's chemical structure -- all steroids share the same chemical backbone of cholesterol, which is why they are placed in the same group. The term "hormone" refers specifically to the molecule's function. A hormone is any chemical signal that travels via the bloodstream. Its chemical structure can be that of a steroid (hence we often talk about steroid hormones), it can be a protein or small peptide (hence protein and peptide hormones), or it can be in another class altogether (such as the catecholaminergic hormones like adrenaline and noradrenaline).

Follicle-stimulating hormone (FSH) is secreted in the bloodstream by the pituitary gland and signals events to occur in distant target organs; thus FSH is a hormone. However, it is made of many amino acids strung together; thus FSH is a protein. So FSH is a protein hormone.

Hope that helps.

What is ETG as related to drug tests?

Ethyl gluconoride is a metabolite of ethanol. It stays in your body for several days after you last drank, so people like probation officers enjoy this test--if you were at a race on Sunday afternoon and you saw one of your clients drinking beers, you can pull him in on Tuesday, test him for EtG and throw him in jail for violating his probation. At least that's the theory. The problem with this test is it triggers on soap--if you wash your hands in a soap containing SD Alcohol 40, you will p*ss hot on the EtG test. I think EtG is a test that will eventually be removed from our battery of usable tests; it's so sensitive it's impossible to use it for what it's there for.

Do labs keep urine after they test it?

There are single-sample tests and split-sample tests. If you've got a split-sample test, the second half of the sample goes into the freezer for six months regardless. For single-sample and the other part of a split-sample test, they retain the sample if it tests positive, but if it tests negative they normally dump it.

How does the baby gets its fathers blood group?

First of all, the baby makes its own blood. Once the baby begins to grow, it forms its own bones, skin, hair, etc. and also begins making blood. The blood type (ie, A, B, AB, or O) is determined by both parents. Type A and Type B are both dominant, which means that if they are there, they will show up. Type O blood is recessive, which means that both parents have to give the baby an O type gene for it to have type O blood. If the baby gets and O gene from one parent and a B gene from the other, it will have type B blood and the O is "hidden". If one gives a B and the other an A the baby will be type AB. Anyway, no blood passes through the umbilical cord. Only nutrients and oxygen are small enough to pass through the filters in the cord. However, during birth, the placenta detaches from the womb and some bleeding occurs. Only at this time can blood from the BABY get into the mother's blood stream. If the baby has a different blood type than the mother, she will make antibodies to the baby's blood. So there is usually no problem during the first pregnancy. NEXT time she gets pregnant, if the baby is a different blood type than the mother, the antibodies that she made during the first birth can cross the umbilical cord into the baby (because they are small enough) and hurt the baby. But there are shots that can be given during the first birth that can "suck up" all the baby's blood cells so that the mother does not make antibodies to them. The only time something could happen to the first baby is if the placenta detaches partially and some bleeding is going on, but not enough to cause miscarriage. This is rare.

How is drug level read in urine test?

in our urine there is protein, when the test solutionsare applied, it causes a break down of the protein and that's when it reads pos. or neg. if there is that certain protein in your system. So I would like to add, there are certain tests/testing methods that are use by certain gov. agencies that no matter what you use to clean/flush your system, you can't bet it. ie; when you" flush" your system, you also get rid of any and all of your protein and to some testers, that's as good as a dirty test. Get it?

Who need iron?

Everyone needs iron. Iron deficiency can lead to anemia, which can cause fatigue, difficulty concentrating, lowered immunity, red or inflamed tongue, and an inability to "stay warm". That being said, some people need more iron than others. Recommended dietary allowances vary by sex and age group. For example, a 21 year-old man may need 8 mg of iron a day, while a woman of the same age requires 18 mg per day. A pregnant 21 year-old woman would need even more iron... about 27 mg per day. Infants and toddlers, female teenagers, womena of childbearing age, pregnant women, people with renal failure, and those with intestinal absorption problems need more iron.
