If you are a student of 11th class biology and looking for the mcqs of chapter 3 then here we have shared the 1st Year Biology Chapter 3 Enzymes MCQs.
• Enzymes are globular proteins
• Co factor= bridge between enzyme and substrate
• Non-protein part covalently bonded to enzyme= prosthetic group
• Loosely attached to protein part= coenzyme
• Enzymes simply dissolved in cytoplasm
• Active site of enzymes= binding site+ catalytic site
• pH
• Pepsin 2
• Sucrase 4.5
• Enterokinase 5.5
• Salivary amylase 6.8
• Catalase 7.6
• Chymotrypsin 7-8
• Pancreatic lipase 9
• Arginase 9.7
• Chlorenchymatous cells carry out photosynthesis
• Cell membrane
• 60-80% protein
• 20-40% lipids
• Peptidoglycan= murien
• Large and small subunit of ribosome attachment is controlled by Mg +2 ion
• Old mitichondria digested by lysosomes by autophagy
• Centrioles play a role in formation of cilia
• Undifferentiated cells have 30000 nuclear pores per nucleus
• Erythrocytes have 3-4pores/nucleus
• Chromosome
• Chimpanzee 48
• Onion 16
• Potato 48
