Answer:
The activity of hexokinase is suppressed by glucose 6-phosphate, which binds to hexokinase at a location that is distinct from the active site this is an example of Feedback inhibition.
Explanation:
Feedback inhibition is a cellular control mechanism in which an enzyme's activity is inhibited by the enzyme's end product.Feedback inhibition is a form of allosteric regulation.Feedback inhibition occurs when the end product of a reaction interferes with the enzyme that helped produce it.With too much product produced, the final product binds to an allosteric site on the first enzyme in the series of reactions to inhibit its activity.. Isoleucine, CTP, and citrate are examples of products that are used in feedback inhibition.
Answer:
non-disjunction leading to trisomy for that gamete
Explanation:
Even with fertilisation being random, these gametes can still be implemented in fertilisation with a regular gamete causing anueploidy - this is the main cause of down syndrome or trisomy 21
Almost all of the plant tissue called cellulose is made up of the cell walls. This is a specialized sugar, and is not used for energy. The correct answer is cellulose.
Answer:
The correct answer is "DnaB propels the PhiX174 phage leading strand synthesis replication fork".
Explanation:
The PhiX174 phage is a DNA virus that infects Escherichia coli. It is false that DnaB propels the PhiX174 phage leading strand synthesis replication fork when the phage replicates. Actually, PhiX174 phage uses the replication machinery of their host to replicate. If the phage faces DNA damage for instance by exposure to UV light, the replication fork overcomes its arrest by the use of the primosome and Rep helicase.
Evolution is the idea that creatures or plants start at a more primitive level and over time adapt to the environment until they are completely adapted. A great example are the finches as depending on what food was available their beak changed over generations to give them an advantage.
