Key or Check List Items Which type of metabolism, anabolism (A) and catabolism (C) are performed by the following organelles. Organelle Metabolism_ 1. Mitochondria …… 2. Lysosomes …… 3. Chloroplasts …… 4. Endoplasmic reticulum (ER) …… 5. Golgi apparatus ……

1-(C) The carbohydrate catabolism is occurs in mitochondria. Mitochondria take in nutrients from a cell, break it down (catabolism) with molecular oxygen and store energy in the form of ATP. 2-(C) Lysosomes contain certain hydrolytic enzymes. These hydrolytic enzymes break down different biomolecules such as fats, proteins, lipids, etc. Glycoproteins are delivered to lysosomes for catabolism. 3-A Chloroplasts follow the process of anabolism because it absorbs sunlight and takes in water and carbon dioxide forming the food for the plants i.e, glucose.In leaves the anabolic pathways are localized in the chloroplast. 4-(A) The endoplasmic reticulum is an organelle present in the eukaryotic cells of plants and animals. Endoplasmic reticulum undergoes the process of anabolism as it is a very important site for the synthesis of lipids and proteins. Organelle Metabolism 1. Mitochondria C 2. Lysosomes C 3. Chloroplasts A 4. Endoplasmic Reticulum A 5. Golgi apparatus A 5-(A) Golgi apparatus are organelles that are involved in the synthesis of lysosomes, packaging of proteins, modification of proteins, etc. It is an anabolic process.

Organelle Storage of protein A Oxysome B Cell Division C 1. Mitochondria B 2.Centrioles C 3.Aleuroplasts A Mitochondria-Oxysome (B). Oxysomes are present in the inner space of the mitochondria. They are attached to the cristae. Oxysomes are involved in the synthesis of ATP inside mitochondria. Centrioles-Cell division(C). The centrioles help in the division of animal cells. The centrioles form spindle fibres that help the chromosome to separate during cell division. Aleuroplast-Storage of protein(A). Aleuroplast is a leucoplast type of plastid that helps in the storage of proteins. Aleuroplasts are mostly found in the seeds of plants.
