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
The statement above is TRUE.
Medical advance refers to the document which a patient write down in advance in other to indicate the type of medical treatment he or she will prefer in case the person become so sick that they can not communicate this need to the health providers again.
The medical assistant in the hospital is the one who act as the patient's coordinator by providing means of communication between the other health providers and the patient. So, it is their duty to ensure that the patient has an advance directive in place.
Sixty-four (64) unique IP addresses could be made in a fixed length IP address system using 6 bits.
The IP address is a number assigned to any item that is connected to the internet. IP stands for Internet Protocol, it's function to work over a dynamic network. It is composed of two parts, it uniquely identifies a specific interface on the network.
