1st Nine Weeks Test Review Name_____________________________________________ 1. Correctly identify each of the biomolecules as a: Carbohydrate, Lipid, Protein, or Nucleic Acid 2. Carbohydrates give the body: circle the correct answer QUICK ENERGY Quick energy long term storage genetic code metabolism/structure 3. Nucleic Acids are responsible the macromolecule that produces what for the body: Circle correct answer Quick energy long term storage Genetic code metabolism/structure Code 4. Lipids man function for the body is: circle the correct answer LONG TERM STORAGE Quick energy long term storage genetic code metabolism/structure 5. Carrier proteins move molecules from an area of low concentration to high concentration. Because they move against the gradient ___ENERGY______________ is needed . circle the correct answer Energy No energy 6. What is the cell membrane mostly composed of? Phospholipids 7. Which requires energy facilitated diffusion or pinocytosis? Pinocytosis cell drinking 8. Which type of transports requires a protein channel or protein carrier? Is this active or passive transport? ACTIVE TRANSPORT 9. Which of the following is an indicator for starch (carbohydrate): circle the correct answer IODINE Iodine Burettes solution bermythal blue 10. Describe how a semi permeable membrane works: It acts like a strainer and only allows certain molecules into or out of the cell 11. If something is impermeable are molecules able to pass through? If something is Impermeable nothing can get through 12. Give an example of how things adapt and evolve over time If an organisms environment changes from a warm one to a cold one over time the species will adapt by growing hair and other traits that will keep him warm 13. What is a function of a protein? Enzymes to catalyze chemical reactions, defense as antibodies, build and repair muscle 14. List two organelles a plant cell has that an animal cell does not Cell Wall, Chlorplast 15. List evidence that support of the Endosymbiotic Theory Mitochondria contain DNA similar to prokaryote’s DNA 16. Why must organism adapt and change over time They will die off if they don’t adapt to changes in their environment 17. Why are protein pumps needed for cell transport? Is energy required for this type of transport? To move molecules into the cell against the gradient. Energy is required 18. List two things the cell membrane is responsible for Maintaining homeostasis and cell structure 19. Describe what happens to a cell when put in a hypotonic solution It gets bigger because there is more water outside the cell and less solutes outside the cell so th3 water will move into the cell due to osmosis 20. Describe what is happening in the picture below Molecules would continue to move until they are both evenly distributed on both sides of the membrane
