Answer:
In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
Explanation:
Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor
Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.
Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.
<h3>How does transcription factors affect gene expression?</h3>
Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control

Answer: Option B) have mitochondria and chloroplasts.
Plant cells have mitochondria and chloroplasts.
Explanation:
Unlike animal cells, plants cells possess mitochondria and chloroplasts. Mitochondria serves as site for respiration giving off oxygen as by-product while chloroplasts are site of photosynthesis, where sugar molecules are formed from simple inorganic molecules like atmospheric carbon dioxide, water and sunlight trapped by chlorophyll.
