II. Modified True or FalseDirections: Write EXACTLY if the statement is true. If the statement is false, encircle the word/s that made the statement false and write the correct answer in the blank space
provided before the number.

1. During the interphase, RNA exists as chromatin rather than as chromosomes

2. A condensed chromosome is made up of four identical sister chromatids
that are densly packed and constricted in a region termed as centromere.

3. Telophase begins when the chromosomes at the start of each pole decondense.

4. In order to finally create two new cells, symbiosis should take place.

5. For some animal cells, cytokinesis is initiated during metaphase where the plane of cleavage is set at right angle to the mitotic spindles.

6. Ribonucleic acid contains the hereditary material in nearly all organisms

7. In plants, mitosis is used to repair damaged cells such as when they are wounded or badly injured

8. Cells that are damaged and lost will be replenished when cells collide.

9. Mitosis is the process in the water cycle that forms identical daughter cells and retains a similar copy of the DNA.

10. In plants, mitosis of nerve tissues is important so as the plants sustain its growth.

11. There are substances like amino acids, glucose and some ions that cannot diffuse freely across the plasma membrane because of the hydrophilic nature of the lipid bilayer.

12. The hydrophilic region is in the form of a head while the hydrophobic part contains two tails of amino acids.

13. Phospholipids and carbohydrates are the principal components of membranes

14. Generally, a phospholipid molecule having both hydrophobic and hydrophilic heads forms the endoplasmic reticulum

15. The structure of the cell membrane plays active and vigor roles in the transport of substances across it.

16. During the intake of large molecules or exocytosis, the portion of the plasma membrane invaginates to enclose the substance

17. If diffusion is taking place across a semi-permeable membrane, the transport is called cell cycle.

18. Proteins can actively pump the molecules coupled with ATP hydrolysis (transport ATPases) and possibly move molecules by cytokinesis

19. In other instances, receptor-mediated exocytosis occurs wherein the molecules can bind to the surface of the membrane

20. Receptor-mediated transport is not compatible with all large molecules due to the specificity of adaptors, similar to the behavior of enzymes.

21. Enzymes are proteins that catalyze chemical reactions by decreasing the activation energy that is needed for the occurrence of any chemical reaction.

22. There are 22 different digestive enzymes that our human body produces

23. The induced fit model was proposed by Daniel Koshland is 1958 which suggests that the active site is continuously reshaped by interactions with the substrate interacts with the enzyme

24. The temperature at which the maximum rate of reaction occurs is called the enzymes optimum pressure

25. Most Enzyme in the human body have an optimum temperature at around 37 degrees Celsius
