Light skin exposed to tropical sun will produce more vitamin D than dark skin, because the UV light is less filtered by the pigment melanin. That is why a light skinned person only needs a few minutes of tropical sun each day to get enough Vitamin D. Any more than that is only increasing the risk of skin cancer. The skin darkens to try to protect you from UV radiation.

Cyanide blocks the last step in the production of ATP. The binding of cyanide to cytochrome c oxidase prevents transport of electrons from cytochrome c to oxygen. No ATP will be produced. The central nervous system and the heart are the most to be affected. Death can occur in minutes.

No it doesn't.

All Vitamin B- complex vitamins are not fat- soluble nor stored in fat of in your body.

No, out of a near infinitude of possible ways to fold, a protein picks one in just tens of microseconds.

Same number of protons, different number of neutrons.

20 to 30 seconds from what i understand.

Assuming you mean "ligases," a ligase is an enzyme that catalyzes the formation of a chemical bond between two smaller molecules to form a larger one. The most common example is DNA ligase, which joins DNA strands together. This occurs on the lagging strand of DNA synthesis where synthesis occurs in short Okazaki fragments. These fragments are joined together by ligase, which acts to "seal the nicks" forming one continuous strand of DNA.

Cells have more proteins than carbohydrates. Proteins are essential components of cell structure and function, playing roles in various cellular processes. Carbohydrates are primarily used for energy production and as structural components in cells.

Common types of hormone treatments include estrogen therapy, testosterone therapy, thyroid hormone replacement therapy, and growth hormone therapy. These treatments are used to manage hormonal imbalances, address deficiencies, or correct hormonal disorders in the body. It's essential to consult with a healthcare provider to determine the most suitable hormone treatment based on individual needs and health conditions.

cell vacuole

Tetrazolium dye is used in cell biology to determine which cells are viable. It is used in cancer treatment to assess the sensitivity of tumor cells to radiation.

The predominant lipids in the lipid bilayer are phospholipids. These include phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin. These lipids have a hydrophilic head and hydrophobic tail, allowing them to form the stable bilayer structure of cell membranes.

Distilled water is evaporated and then condensed, so it has absolutely no contaminates. Unwanted compounds in medicine could be very dangerous.

if you lack vitamin a you get night blindness

The enzymes salivary amylase and pancreatic amylase catalyze the cleavage of alpha 1-4 glycosidic linkages on complex and simple carbohydrates.

If you think to Lugol, this solution is used as antiseptic, disinfectant, source of iodine, reagent for starch detection, reagent to detect some microbes, etc.

Purines bond to pyrimidines in nucleic acid DNA .

enodcrine

The phrasing is a little odd, but I suspect the term you're looking for is "alpha helix". Other "twisting spiral shapes" are possible, for example the 3.10 helix and the pi helix, but the alpha helix is the most common and most familiar.

All bacteria produce chemicals. Could you possibly be more specific?

Na is Sodium, and since everything is made of molecules, I would assecertain that NA is therefore a molecule.

Dentine and cementine contain specific proteins as proteoglycans, collagene and other.
