Answer:
A- A pH change can cause the enzyme to change its shape
Explanation:
A rise or fall in the pH of the medium from the optimum of pH 7 usually affect the enzymes' active sites of and therefore the shape and the rate of enzyme activity.
Assuming the pH is too low, the enzyme medium becomes acidic;Acidosis. The high Hydrogen ions concentration interacts with the R-groups of the amino acids moiety of the enzymes, this interaction affects the ionization of the R-groups, disrupting the ionic bonding holding these R-groups in shape.
This results in loss of the 3-Dimensional shape arrangements of the protein molecule and therefore of the active sites. Since active sites of enzymes determines the specificity of the <u>enzymes substrate- complex </u> to give <u>enzyme-product complex,</u> the catalytic activity of the enzymes decreases, <u>the rate of reaction decreases,and products formation stops, and the reaction also stops.</u>
The same is applicable to extremely high pH=Alkalosis.
However, the effective buffer system of the body prevents this scenarios from happening in real sense in the body. Through mopping by the haemoglobin, excretion by the kidney, etc
Answer:
The correct answer is
Option C. Season.
Explanation:
Jupiter has no seasons, while Uranus, with a spin axis tiled 98 degrees, has the most extreme ones. Tilting of planets are responsible for season. If there is very low tilting, the seasons are not present. In jupiter the tilting is very low that is 3 degree so that's why jupiter has no seasons. In earth, the seasons are present due to high tilting i. e. 23 degree.
The portion of a muzzle-loader rifle that fits against your shoulder is the - BUTT.
A muzzle-loader is a firearm in which the projectile and usually the propellant charge is loaded from the muzzle of the gun. This is distinct from the more popular modern designs of breech-loading firearms. That portion of a muzzle-loader rifle that fits against ones shoulder is called the butt.
