Answer:
Liver, 25-hydroxycholecalciferol.
Explanation:
Vitamin D is a fat soluble vitamin that increases the absorption of phosphate and calcium in the body. Vitamin D2 and D3 are most important for the human health.
The hydroxylation of cholecalciferol occur in the liver in order to be active vitamin D. The first hydroxylation of cholecalciferol produces 25-hydroxycholecalciferol.
Thus, the answer is liver, 25-hydroxycholecalciferol.
It is an example of an Prokaryotic cell.
Answer: within the cytoplasm of the cell
Explanation:
There are four main types of receptors, these are:
G-protein linked Receptors
Enzyme-Linked Receptors
Nuclear Receptors
Ligand-Gated Ion Receptors
Out of these four types; It has become apparent that ligand-gated ion channels (ionotropic receptors) in the neuronal plasma membrane interact via their cytoplasmic domains (i.e within the cytoplasm of the cell) with a multitude of intracellular proteins. Another fact is that, Intracellular receptors are located in the cytoplasm of the cell. Also, Ligand-Gated Ion Receptors is the only Hydrophilic Ligand.
Unlike the G-protein linked Receptors (transmembrane protein (TP)). A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the cell membrane. They frequently undergo significant conformational changes to move a substance through the membrane. They usually highly hydrophobic and aggregate and precipitate in water.
Enzyme-Linked Receptors are transmembrane proteins as well, with their ligand-binding domains on the outer surface of the plasma membrane. They are also hydrophobic in nature.
Nuclear Receptors are nuclear hormone receptors that directly binds within the nucleus of the cell to regulate the expression of targeted genes.
Answer:
In genetics, epistasis occurs when two or more different gene loci contribute to the same phenotype. ... Therefore, epistasis is often described as occurring when one gene locus masks or modifies the phenotype of a second gene locus. The term epistatic is used to describe the relationship between two genes in epistasis.
Explanation:
<h3><u>Answer;</u></h3>
To detoxify various drugs in the liver
To break down proteins and phospholipids to produce ATP
<h3><u>Explanation</u>;</h3>
- Peroxisomes are organelles in the cell that are membrane bound and contain enzymes crucial for metabolic activity.
- Peroxisomes break down fatty acids to use as cellular fuel & detoxify harmful compounds in liver (enzymes transfer H from compounds to O producing hydrogen peroxide H2O2). This toxic by product is converted to water by other enzymes (importance of compartmentalization)
