the answer is all of the above
Answer:
The options
A. Methylation
B. Dephosphorylation
C. Phosphorylation
D. Enzymatic transformation
The CORRECT ANSWER IS B.
B. Dephosphorylation
Explanation:
The regulation of the phosphorylation of myosin light chain (MLC) is a major step in the regulation of smooth muscle cell contraction.
The dephosphorylation of myosin light chain (MLC) occurs in smooth muscle tissue and causes the relaxation phase of the muscle cells. This step is controlled by the MLC phosphatase (MLCP).
<span>Cell membrane plays an important role in maintaining the homeostasis by controlling the substances that penetrate the cell, either entering the cell, or leaving the cell. Since the cell membrane is a phospholipid bilayer, it can control the transition of water and ions.</span>
Answer:
C Halobacterium species
Explanation:
ThIs is because this species of bacteria thrive well in high salt concentrations; and will be inactive in a low salt concentration medium.They are known as Hallophilic Organisms. (salt organism)s
They are rod-shaped, motile organisms , which reproduced by binary fission,live in saline lakes, with the cell bounded by a single layer of plasma membranes.They contain beta-caroteen pigments. it is this that is responsible for their red coloration.When this pigment is extracted, is used in food dye. giving food red coloration.
In addition, Halo. Bacteria contain some enzymes that can break dowm organic molecules to simplest forms. These are Degredative enzymes.(e.g Lipase , Amylases). it is this feature that aids their application for aiding the process of fermentatio<u>n of salty foods</u>, and also aiding of <u>coffee processing during production. </u>
<u>Since this is called a salty bacterium, and its enzymes will be most active in high salty concentrations, then option C is the correct answer.</u>
