Lysosomes contain hydrolytic enzymes for digesting waste materials and cellular debris. The smooth endoplasmic reticulum is involved in lipid synthesis, detoxification, and calcium storage, but not protein synthesis (which occurs on rough ER due to attached ribosomes, or free in the cytoplasm).<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>In a mammalian cell, the protein is synthesized by [amp_mcq option1=&#8221;Ribosome.&#8221; option2=&#8221;Golgi.&#8221; option3=&#8221;Lysosome.&#8221; option4=&#8221;Smooth endoplasmic reticulum.&#8221; correct=&#8221;option1&#8243;] This question was previously asked in UPSC CISF-AC-EXE &#8211; 2021 Download PDFAttempt Online Ribosomes are small organelles found in the cytoplasm of all cells (prokaryotic and eukaryotic), as well as attached to the endoplasmic reticulum in eukaryotic cells. &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"In a mammalian cell, the protein is synthesized by\" class=\"read-more button\" href=\"https:\/\/exam.pscnotes.com\/mcq\/in-a-mammalian-cell-the-protein-is-synthesized-by\/#more-92975\">Detailed Solution<span class=\"screen-reader-text\">In a mammalian cell, the protein is synthesized by<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1089],"tags":[1110,1117,1152],"class_list":["post-92975","post","type-post","status-publish","format-standard","hentry","category-upsc-cisf-ac-exe","tag-1110","tag-biology","tag-cell","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>In a mammalian cell, the protein is synthesized by<\/title>\n<meta name=\"description\" content=\"Ribosomes are small organelles found in the cytoplasm of all cells (prokaryotic and eukaryotic), as well as attached to the endoplasmic reticulum in eukaryotic cells.
