Eukaryotic cells

• Nucleolus - site of ribosome synthesis
• Ribosomes are found both free floating or attached to the endoplasmic reticulum (ER). They consist of two subunits made up of proteins and RNA.

• Mitochondria are responsible for cellular respiration and energy production through oxidative phosphorylation.
• Mitochondria are responsible for cellular respiration and energy production through oxidative phosphorylation.
• Lysosomes contain hydrolytic enzymes that break down macromolecules into smaller molecules.
• The ER is continuous with the outer membrane of the nucleus, forming nuclear pores that allow transport between the cytoplasm and the nucleus.

• Chloroplasts contain chlorophyll and are involved in photosynthesis.
• Chloroplasts contain chlorophyll and are involved in photosynthesis.
• Glycosylation occurs when carbohydrates are added onto proteins by enzymes located within the Golgi apparatus.
• The ER has three main functions: production of lipids such as phospholipids and cholesterol, detoxification of drugs and other foreign molecules through enzymes called cytochrome P450 monooxygenases, and secretion of proteins into the bloodstream via vesicles.
• Lysosomes contain hydrolytic enzymes that break down macromolecules into smaller molecules.
• The Golgi apparatus is responsible for processing, sorting, packaging, and modifying proteins and lipids produced by the ER.
• Golgi apparatus consists of flattened sacs called cisternae arranged in stacks.
• Lysosomes contain hydrolytic enzymes that break down macromolecules such as carbohydrates, fats, nucleic acids, and proteins.
