Topic 3: 200 Question: Which line represents a reaction with the help of an enzyme? Answer The Blue Line Back

Topic 3: 400 Question: How do enzyme speed up a reaction? Answer By lowering the activation energy (Energy needed for the reaction to happen) Back

Topic 3: 600 Question: What are four structures on your body formed from protein? Answer Hair Nails Skin Muscles Back

Topic 3: 800 Question: What are the four functions of lipids? Answer Cushions organs Forms membranes Chemical Messenger (Steroids) Long term energy Back

Topic 3: 1000 Question: Identify the following monomers 1. 2. 3. 1. 2. 3. Answer 1. Glycerol & Fatty Acids (Lipid) 2. Nucleotide (Nucleic Acid) 3. Amino Acid (Protein) Back

Topic 4: 200 Question: What organelle is responsible for turning food into energy ? Answer Mitochondria Back

Topic 4: 400 Question: Give one example of a prokaryote and a eukaryote. Answer Prokaryote = bacteria Eukaryote = any Animal, any plant, Any Fungus (ex. – mushroom) Back

Topic 4: 600 Question: What are the three parts of the cell theory? Answer All cells come from preexisting cells Cells are the basic structure and function in all living things All living things are made of cells Back

Topic 4: 800 Question: List three characteristics for prokaryotic cells and eukaryotic cells. Answer Prokaryotes Eukaryotes small large simple complex No organelles organelles No Nucleus Nucleus Back

Topic 4: 1000 Question: Identify the cell and letters A, B, C, D, E, F, K, J Answer Topic 4: 1000 Back

Topic 5: 200 Question: Why is a cell membrane called semipermeable? Answer Because it allows certain molecules to pass in and out but prevents others from entering or leaving the cell. Back

Topic 5: 400 Question: What are the three macromolecules that make up the cell membrane? Answer Lipids, proteins, and carbohydrates Back

Topic 5: 600 Question: What is the difference between passive transport and active transport? (explain energy and concentration) Answer Active transport requires energy and moves solutes from low to high concentration, while passive transport does not require energy and moves molecules from high to low. Back

Topic 5: 800 Question: Name all the forms of passive transport in a cell and explain how each works. Answer Diffusion – small, non-polar molecules squeeze through lipid bilayer Facilitated diffusion – big, polar molecules need a protein channel to go into or out of cell Osmosis – The movement of water across the lipid bilayer or through channel proteins Back

Topic 5: 1000 Question: Answer Name all forms of active transport (including subcategories) and how they work. Answer Protein Pumps – Proteins in the cell membrane use energy to pump molecules from low to high concentration Endocytosis – Cells use energy to engulf molecules by pinching off part of their membrane Pinocytosis – the engulfing of liquids Phagocytosis – the engulfing of solids Exocytosis – Cells use energy to fuse vacuoles of waste to cell membrane and then release outside of cell Back

Bonus Question: 5000 pts. Question: In what object of a plant does photosynthesis take place? Answer … chloroplast Back
