An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell. Hope this helps. :)
Human cells spend most of their time in interphase, where they do not divide. In interphase, a cell may grow, obtain and nutrients and metabolize them, read DNA, etc.
Correct answer: A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
Cellulose is found in the cell walls of plant cells. It is permable so any substance disolveabls in water can pass through so it dose not act as a barrier. It gives the cell its strength and support. As water moves in to the cell by osmosis it stops the cell from bursting.
Answer:
if mitosis is unregulated, cancer cells could multiply continuously or create defective daughter cells.
