Phenylalanine hydroxylase (PHA) performs an enzymatic function during the conversion of phenylalanine, to tyrosine. Existing naturally in several types of foods, for instance, breast milk, PKU is an essential α-amino acid and one of the plethora of amino acids used in the formation of proteins. Phenylalanine exists in three forms; L-phenylalanine, D-phenylalanine (mirror image of L-phenylalanine), and DL-phenylalanine which is a typic combination of D and L-phenylalanine, and unlike D and L- phenylalanine, is not found in foods. On the other hand, tyrosine, apart from being a derivative of phenylalanine, is a non-essential amino acid that forms part of the list of amino acids utile during the constitution of proteins. Ordinarily, lack of PAH leads to the accumulation of phenylalanine (the phenylalanine is not converted to tyrosine) leading to the development of a disease called Phenylketonuria (PKU).

If the capillary hydrostatic pressure (CHP) is elevated, what consequences will this have on the surrounding tissues
Increased capillary hydrostatic pressure produces excess and accumulation of interstitial fluid in the surrounding tissues. It is called edema.
What is edema?Edema can be defined as excess and accumulation of interstitial fluid in the surrounding tissues.
Increased capillary hydrostatic pressure is a primary cause that may lead to the formation of edema.
Edema can be localized to a specific body region (e.g., pericardial effusion, etc) or also produce a systemic formation (anasarca).

How are molecules transported across cell membrane against the concentration gradient?.
Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."

Explanation:
Specific lipoproteins called _______________ will be needed to transport fat from your meal through the bloodstream because triglycerides and fatty acids are ___________________.
Answer:
The largest lipoproteins, which primarily transport fats from the intestinal mucosa to the liver, are called chylomicrons. They carry mostly fats in the form of triglycerides. In the liver, chylomicron particles release triglycerides and some cholesterol.
Chylomicrons are the specific lipoproteins which are needed to transport fat from meal to the bloodstream. This is because, triglycerides cannot pass the cell membrane on their own.
What are Triglycerides?Triglyceride is a type of fat (lipid) found in the blood. When a person eats, the body converts calories it doesn't need to use urgently into triglycerides. The triglycerides are stored in the fat cells of the body. Later on, hormones release triglycerides for energy between meals.
Chylomicrons are the large triglyceride-rich lipoproteins produced in enterocytes from dietary lipids. Triglycerides are transported by these most lipid-rich of the lipoprotein particles, namely, chylomicrons and very low density lipoproteins (VLDL). Triglycerides cannot pass the plasma membrane of cell on its own and hence require these proteins.

Answer:
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions..
There are two distinct types of cells: prokaryotic cells and eukaryotic cells. Though the structures of prokaryotic and eukaryotic cells differ (see prokaryote, eukaryote), their molecular compositions and activities are very similar. The chief molecules in cells are nucleic acids, proteins, and polysaccharides.

Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

synaptic cleft
Answer:
The synaptic cleft
Explanation:
Neurons are separated by junction areas known as synapses, areas where the terminal buttons at the end of the axon of one neuron nearly, but don't quite, touch the dendrites of another. The synapses provide a remarkable function because they allow each axon to communicate with many dendrites in neighboring cells.
