8. In catabolism Complex or polymeric molecules are degraded into small molecules and energy
is consumed Polymeric and complex molecules are synthesized from small molecules and energy
is released Complex or polymeric molecules are degraded into small molecules and energy is
released Polymeric and complex molecules are synthesized from small molecules and energy is
consumed A. B. C. D. Which of the following organelle is considered to be the result of
endosymbiosis A. ribosome B. Smooth Reticulum C. nucleus D. mitochondria 9.
Solution
Answers: 8. Option C: Complex or polymeric molecules are degraded into small molecules and
energy is released
9. Option D: Mitochondria
Explanation:
8. Catabolism (Breaking up process) is the process where macromolecules are broken down into
small molecules with release of energy. So. option A which states that energy is consumed is not
a correct answer
The energy thus lliberated during catabolism process is used to form macromolecules which is
termed as Anabolism (building up process) So, option B is defines anabolism except for the
wrong statement that energy is released. In anabolism energy is consumed
Option D is the statement related to Anabolism as discussed above
Hence, option C is the correct statement. (Catabolic and anabolic activities are together called as
metabolism)
9. Mitochondria called as power house of the cell is said to be the evolution of prokaryotic cells.
The engulfing vesicle is represented as outer mitochondrial membrane.
In plant cells, chloroplast is the result of endosymbiosis.
The remaining options in the given question are not related to endosymbiosis. Ribosome is
evolved from the RNA whose evidence was drawn from LUCA(Last universal common
ancestor). Smooth endoplasmic reticulum, rough endoplasmic reticulum, golgi apparatus,
lysosomes are evolved from the invagination of plasma membrane. Nuclear pore complexes and
nuclear membranes are coevolved with endomembrane system.
Thus, the correct answer is D. Mitochondria
