Answer:
Binding of glucose to hexokinase causes a conformational change in the enzyme. This is an example of the<u> induce-fit </u>model of enzyme catalysis.
Explanation:
The induce- fit model is generally the most accepted theory for enzyme catalysis. This theory states that the active site of an enzyme is not always a perfect fit for a substrate. The substrate induces changes in the active site so that it can fit into the active site. This theory is contrary to the theory of lock and key model, which stated that substrates exist as a perfect match for particular active sites of an enzyme.
Answer:
38.
Explanation:
All water that are present in soil is not available for the plants. Gravitation water is present in soil due to the gravitational force. The gravitation water remains for short time and cannot be consumed by the plants.
The capillary water is available to the plants and this water is attained in the soil pores. The total water present in soil sample is 100 ml. 62ml is gravitation water. The volume of capillary water = total water - gravitation water = 100 - 62 = 38ml.
Thus, the answer is 38ml.
Answer:
The correct answer is ''METAPHASE I.''
Explanation:
Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
Hello! :)
It would take forever listing all the animals that have adaptations that helps them survive in their environment.
Natural selection is the process by which individuals with characteristics that are advantageous for reproduction in a specific environment leave more offspring in the next generation, thereby increasing the proportion of their genes in the population gene pool over time.
Hope this helped and I hope I answered in time!
Good luck!
