Question

which per Alla hotell you sweden and stop Which of radiatica consists of an electrons that is wewed by the suces of anom . This is called 12. The formation of sucrose involves the removal of a molecule of ww hydrolysis. decomposition dehydration synthesis Which of the following is not a major function of protein? Provides structure for the body Acts as a catalyst for chemical reactions in the form of enormes Provides energy for the body All of the above are functions of protein. 14. Main cell structures include all of the following except: a organelles. bplasma membrane interstitial fluid. d cytoplasm. IS. Each of the following is an example of the plasma membrane function except: a boundary. b self-identification 6. receptor sites d. production of proteins. 16. Which of the following structures contains DNA?

Answer 1

9. d) Correct answer - all require energy. Statement is quite self explanatory

A - Synthesis reactions require energy to fuse substrates into the final product

B- Decomposition. Energy is required to break down the bonds.

C- Exchange reactions need energy to exchange functional groups.

Thus, d (all of the above) is the appropriate answer.

10. d) 96% - correct answer. 96% of the body is made composed of C, H, O and N.

a, b,c - wrong percentages. Correct percentage is 96%. Hence these options are wrong.

11. b) - Beta rays is the correct answer. Beta rays are composed of electrons that are released from the nucleus.

A- Alpha rays - Made up of helium nucleus

C- Delta waves. An electron ejected by recoil when a rapidly moving alpha particle or other charged particle passes through matter.

D- Form of electromagnetic radiation.

12. d)- Dehyration synthesis is the correct answer. In dehydration synthesis of a compound, a compund is synthesised by the removal of water from substrates and joinining substrate molecules together.

A- Hydrolysis - Lysis of a comound in the presence of water

B - Oxidation is the addition of oxygen, removal of a proton or loss of an electron.

C - Decomposition is a process by which a compound degenerates into less complex products.

13. D) All of the above is the correct statement. Options A, B and C are all functions of proteins.

A - Provides structure to the body. True statement. Proteins are components of structural elements of the body like body, cartilage and other connective tissue.

B- Act as catalyst. This is true as proteins in the form of enzymes catalyse reactions.

C- Provide energy. This is also true. After carbohydrates and fats are exhausted, proteins are also utilised as a source of energy.

14. C) Interstitial fluid - correct answer. This is not a component of a cell. It is present outside the cell in the interstitial space.

A - Organelles - Are present inside the cell

B- Plasma membrane - Essential component of cell

D- Cytoplasm - It is the matrix within the cell in which all cell organelles are present

15. D- production of proteins. This is not a function of the cell membrane. Proteins are produced by ribosomes and Rough endoplasmic reticulum.

A, B and C - All are functions of the cell membrane.
