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
❤️Hello!❤️ In my opinion, i'm against GMO's. First of all you need to understand what GMO stands for, GMO means (Genetically Modified Organisms) and does that REALLY sound appealing to eat (Be honest). So now we have that covered i'm going to tell you some reasons why YOU should avoid Genetically Modified Organisms (GMO's). First of all GMO's are unhealthy, according to the American Academy of Environmental Medicine. They cite animal studies showing organ damage, gastrointestinal and immune system disorders, accelerated aging, and infertility. Second of all, GMO's contaminate forever. GMO's cross pollinate and their seeds can travel. It is impossible to fully clean up our contaminated gene pool. Self propagating GMO pollution will outlast the effects of global warming and nuclear waste. The impact is huge, threatening the health of future generations. Third of all, GMO's increase herbicide use, most GMO crops are engineered to be “Herbicide tolerant”―they deadly weed killer. Monsanto, for example, sells Roundup Ready crops, designed to survive applications of their Roundup herbicide. Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GMO's. Overuse of Roundup results in “superweeds,” resistant to the herbicide. This is causing farmers to use even more toxic herbicides every year. ♒️ Hope this helps!♒️ ↪️ Autumn ↩️
Its false because lobsters have swimmerets as well and they dont use them only for swimming
Answer:
evolution of bidepadlism,
increase in enamel thickness,
regular use of stone tools, enlargement of brain to around 1,450 cc
Explanation:
Answer:
The answer is "TRUE!"
Explanation:
Weight is a source of forceful motion that is generated by the pull of gravity. Gravity that is originated in the center of the earth, attracts smaller objects towards that center, in which the measurement of how strong that force really is, is weight.
