  1. Cellular Functions A Review of Vocabulary

  2. Sugars and starches are? • Lipids • Carbohydrates • Proteins • Enzymes

  3. What do carbohydrates provide? • Space • Energy • Liquids • Enzymens

  4. What are molecules that make up membranes of cells and organelles? • Lipids • Proteins • Carbohydrates • Enzymes

  5. What are important because they carry out many of the activities of a cell? 1. Cytoplasm 2. Chloroplasts 3. Chlorophill 4. Proteins

  6. What are molecules that carry the information cells need to grow, reproduce, and repair themselves? 1. Cytoplasm • Nucleic acids • Proteins • Chloroplasts

  7. Why is water important to a cell? • Many of the chemical reactions inside a cell take place in water. • The cell is made up of 1/5 water. • Water is not important

  8. What are many of the molecules of a cell made up of? • Chains of carbon atoms • Cytoplasm • Stuff • Chlorophyll

  9. What must a cell release, that is stored in a molecules bond, in order to stay alive? • Cytoplasm • Proteins • Enzymes • Chemical Energy

  10. What is the process by which plants produce glucose and oxygen? • Fermentation • Photosynthesis • Proteins • Exocytosis

  11. A major source for most cells is a sugar molecule called _____? • Cytoplasm • Chlophyll • Glucose • Chocolate

  12. Cells use oxygen to release the energy in glucose during ________ ? • Cellular respiration • Fermentation • Endocytosis • Exocytosis

  13. In what organelle does cellular respiration take place? • Nucleus • Lysosomes • Chloroplasts • Mitochondria

  14. If a muscle cell does not have enough oxygen, it can still release energy through what process? • Photocynthesis • Fermentation • Endocytosis • Exocytosis

  15. What describes the amount of material dissolved in a certain amount of liquid? • Concentration • Diffusion • Frustration

  16. What is the process by which molecules spread out in all directions to move toward an equal distribution? • Concentration • Diffusion • Lipids • Polar

  17. In order for material to cross into and out of the cell, what must it pass? • Nucleus • Chloroplasts • Cell membrane • Lysosomes

  18. Through what process can a cell membrane absorb a virus? • Exocytosis • Endocytosis • Cellular Respiration • Photosynthesis

  19. Through what process can materials move into and out of a cell without using energy? • Photosynthersis • Active transport • Cellular Respiration • Passive transport

  20. What is the diffusion of water into and out of the cell? • Diffusion • Osmosis • Central Vacuole • Concentration

  21. What do cells use to move substances from an area of lower concentration to an area of higher concentration? • Active Transport • Passive Transport • Photosynthesis • Fed Ex

  22. What process do cells use to expel large molecules such as proteins? • Cellular Respiration • Photosynthesis • Endocytosis • Exocytosis

  23. How are carbs and lipids alike? • 1. They both store energy • 2. They both repel water • 3. They have the same atom arrangement • 4. They are both made of chlorphyll

  24. What is true about Enzymes? • They control the speed of chemical reactions. • They are proteins • Both 1 and 2 • Neither 1 nor 2

  25. What do exocytosis and endocytosis have in common? • They move material into cells. • They move material into and out of the central vacuole. • The cell membrane surrounds material that needs to be transported. • They move material out of cells

  26. What determines how fast materials move in and out of cells? • How much cytoplasm is in a cell. • How big the central vacuole is. • The cell’s size • Amont of glucose available
