Biology
1 answer:
Tema [17]3 years ago
3 0

The right answer is True.

In cell biology, an undifferentiated cell is a stem cell capable of both generating specialized cells by cell differentiation and to maintain itself in the body by proliferation or asymmetric division.

During the first division of the stem cell, it remains undifferentiated, then, as the number of division increases, the cell chooses a differentiation pathway and becomes more and more differentiated and transforms into a specialized cell.

Increasing the substrate concentration in an enzymatic reaction could overcome which of the following?
bixtya [17]

Answer:

(C) Competitive inhibition

Explanation:

When a substrate competes with and inhibitor, what they are actually doing is competing by the active site of the enzyme. In terms of probabilities, when there is much more of one molecule of X than its competitor Y, it is more likely for any of the molecules of X to reach the active site of the enzyme than for any of the molecules of Y.

Then is one would like to reduce the effects of an inhibitor reversible bonded to an enzyme, one possibility is to increase the concentration of a substrate (which in turn means that there will be a higher relative number of its molecules in the media), increasing the probability to meet the active site of the enzyme and as a result displacing the inhibitor (assuming it not increased as well).
