Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
Answer:
Biology can simply be described as the study of living organisms. Biology is divided into many sub categories depending on the features of life that we want to study. For example, molecular biology is the study of molecules which make up living organisms.
Zoology can be described as a branch of biology under which animals are studied. The field of zoology involved studying the taxonomy of animals, their evolutionary histories, physiology, embryology etc. All these studies are parts of biology hence zoology and biology are related.
Apart from these other unifying principles shared between zoology and biology are genetics, cell biology, population biology,biochemistry etc.
