Answer:
Kinase is a collective name for a group of enzymes that can apply a phosphate group to another protein or molecule (phosphorylation), while a phosphatase can remove such a group (dephosphorylation). A kinase uses kinetic energy in this catalytic reaction, hence the name kinase.
Often, such a phosphorylation or dephosphorylation activates or deactivates the target protein. This switching function can thus control chemical reactions in the cell and is an important factor in cell-internal signal transduction.
Answer:
The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
Answer:
Posology prevents patients from taking under dose or over dose.
Explanation:
Posology deals with dosage of medics as prescribed to the patient.
There is no proof that vitamin E or selenium supplementation helps stop prostate cancer.
Those who entered the trial with elevated selenium levels saw an increased impact of potential prostate cancer, whether selenium was taken alone or in conjunction with vitamin E, but not men who started the research with moderate selenium levels.
According to this meta-analysis, selenium most likely has a preventive function in preventing prostate cancer from developing and progressing to advanced stages. So, selenium treatment can be suggested for prostate cancer prevention.
For certain enzymes and proteins, known as selenoproteins, to function and guard against cellular damage and infections, as well as help build DNA and regulate the synthesis of thyroid hormones, selenium is a necessary component.
