Answer: c. proteasome
Explanation:
Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.
Answer: C
Explanation: The two chromatids of a duplicated chromosome are held together at a region of DNA called the centromere. Centromeres are the attachment points for microtubules, which are responsible for the guiding the movement of chromosomes during mitosis and meiosis.
<em>They are exothermic as they take temperature from the surrounding and then maintain their internal body temperature according to the amount of heat absorbed :)</em>
Answer:
photosynthesis produces glucose which is stored as starch in the plant.
Explanation:
6H₂O + 6CO₂ -----> C₆H₁₂O₆ + 6O₂(as a waste product for plants)
Photosynthesis reduces carbon dioxide in the atmosphere which reduces the green house gasses in the atmosphere which reduces the green house effect.
