The question is incomplete as it does not have the options which are:
a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
b. The woman may have different gender babies.
c. The woman with less stretch marks has larger skin cells.
d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.
Answer:
The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
Explanation:
The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.
These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.
Thus, the selected option is correct.
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.
