Question

chapter 3. organelles. warning! just studying these answers does not mean that you will understand this information. you are responsible for reading the textbook and understanding the functions and composition of each organelle listed below. answers to the blanks below. each answer can only be used once. cytoplasm cytoskeleton rough endoplasmic reticulum ribosome golgi apparatus smooth endoplasmic reticulum mitochondria lysosomes peroxisomes centrioles cilia flagella vesicles 1. the __________ is an organelle that serves as the site of protein synthesis. name two locations that these organelles can be found within the cell. a. b. 2. the ________ is a large membranous organelle, composed of lipids, that receives vesicles carrying proteins from the rough endoplasmic reticulum. here the proteins are further modified and transported outside the cell by using a ________. 3. ________ are found in every cell, but are most abundant in liver and kidney cells. these small sacs contain over 40 enzymes that detoxify h₂o₂, alcohol, toxins and break down and digest unneeded cellular components. 4. ________ are the \garbage disposals\ of the cell. these sacs contain 40 or more enzymes that digest molecules found on foreign cells or old worn - out organelles. 5. the ________ is the mass of fluid that is found inside the cell membrane and around the nucleus. 6. the ________ is an organelle that composed of a lipid membrane and is primarily responsible for the synthesis of lipids: steroids, triglycerides, and phospholipids. 7. the ________ is an organelle that is composed of a lipid membrane which is embedded with ribosomes. this is responsible for modifying proteins already constructed by other organelles and then transporting them to the golgi apparatus. 8. the ________ are organelles that have a double layered lipid membrane, contains its own dna, and is used to generate atp (cellular energy) when o₂ is present within the cell. 9. the __________ are organelles only used during cell division and

Explanation:

1. Ribosomes are the sites of protein synthesis and can be found in the cytoplasm and on the rough endoplasmic reticulum.
2. The Golgi apparatus receives vesicles from the rough ER, modifies proteins and uses vesicles to transport them out of the cell.
3. Peroxisomes are abundant in liver and kidney cells and detoxify substances and break - down cellular components.
4. Lysosomes are the cell's "garbage disposals" with enzymes to digest foreign or old organelles.
5. Cytoplasm is the fluid inside the cell membrane around the nucleus.
6. The smooth endoplasmic reticulum is responsible for lipid synthesis.
7. The rough endoplasmic reticulum has ribosomes embedded and modifies and transports proteins to the Golgi.
8. Mitochondria have a double - lipid membrane, their own DNA and generate ATP.
9. Centrioles are only used during cell division.
