What conclusion can be drawn concerning an inhibitor if the Km is the same in the presence and absence of the inhibitor

Answers

Answer 1

Answer: The inhibitor has a structure that is not similar to the substrate.

Explanation:

Enzymes are molecules that act as catalysts of chemical reactions, accelerating the reaction rate without affecting the equilibrium of the reaction, as long as it is energetically possible. They act on molecules called substrates, which are converted into different molecules called products.  

Enzymes are very selective with their substrates and are also susceptible to inhibitors which are molecules that regulate enzyme activity, inhibiting its activity. Inhibitors can be classified as reversible and irreversible. Irreversible inhibitors bind covalently to the enzyme with no possibility of reversing the modification they make, while reversible inhibitors bind reversibly to the enzyme and can reverse the modification.

A reaction occurring under the control of an enzyme reaches equilibrium much faster than the corresponding uncatalyzed reaction. The reaction, i.e. the production of products, can reach a saturation point if the substrate concentration increases too much, decreasing the concentration of free enzyme, which becomes the form with bound substrate. At the maximum rate (Vmax) of the enzyme, all active sites of the enzyme have substrate bound, and the amount of complexes is equal to the total amount of enzyme. The amount of substrate required to obtain a given reaction rate is also important and this parameter is given by the Michaelis-Menten constant (Km), which is the concentration of substrate required for an enzyme to reach half its maximum velocity. Each enzyme has a characteristic Km value for a given substrate, which can tell us how close the binding between the substrate and the enzyme is. Then, inhibitors bind to the substrate and increase the Km value as it interferes with the binding between substrate and enzyme. In this case, the Km value of the enzyme is the same in the presence and absence of the inhibitor, this means that there is no change, because the inhibitor has a different structure to the substrate, it does not bind and does not change the Km value.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones

Answers

Answer:

Provides more strength.

Explanation:

It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.

B) Uniform in the genetic information they contain

C) Separated by large sketches of repetitive DNA

D) Each void of typical protein-coding sequences of DNA

E) Void of introns.  

The correct answer is A.

Explanation:

The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.

In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.

Answers

Answer:

A

Explanation:

The correct answer would be that the sperms are changing chemical energy to kinetic energy.

In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells.  Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.

The correct option is A.

Answers

Answer:

can be recharged with the uptake of energy to form ATP

Explanation:

The correct answer would be that the ADP can be recharged with the uptake of energy to form ATP.

ADP is converted to ATP within a cell when free energy is available. The free energy is stored by coupling a phosphate group to ADP to form ATP, such that:

ADP + P (inorganic) + Free Energy ------> ATP

Hence, ADP can only be recharged with the uptake of energy to form ATP, a kind of reaction generally referred to as endergonic reaction.
