TOPIC: Cell Processes AIM: Explain the two types of respiration. Do Now: (Take out your flippy cards) 1. Explain two differences between passive and active transport. 2. Identify the 2 types of passive transport and the difference between the two. HW: Bring in Science Board Wednesday or Monday! Review: Which process requires cellular energy? 1. diffusion 2. passive transport 3. active transport 4. osmosis Sodium ions are pumped from a region of lower concentration to a region of higher concentration in the nerve cells of humans. This process is an example of 1. diffusion 2. osmosis 3. passive transport 4. active transport The movement of materials from higher to lower concentration is called 1. diffusion 2. active transport 3. pinocytosis 4. phagocytosis Damage to which structure will most directly disrupt water balance within a single-celled organism? 1. ribosome 2. cell membrane 3. nucleus 4. chloroplast Cell • Glucose (sugar) is Respiration broken down to make ENERGY (ATP) • Occurs in mitochondria • Carried out by every living thing!!! • Oxygen (O2) required Aerobic Respiration to make energy Oxygen Carbon dioxide & water vapor EQUATION C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP GLUCOSE + OXYGEN CARBON + WATER + ENERGY DIOXIDE WASTES (breathe out) Anaerobic • Energy produced Respiration WITHOUT oxygen • FERMENTATION • Occurs in the cytoplasm EQUATION C6H12O6 6CO2 + 2ATP GLUCOSE CARBON DIOXIDE + ENERGY TOPIC: Cell Processes AIM: Explain the two types of respiration. Do Now: (Take out your flippy cards) 1. Identify what is produced during aerobic respiration. Anaerobic respiration? 2. Identify what is produced during aerobic respiration. Anaerobic respiration? HW: Bring in Science Board Wednesday or Monday! Aerobic respiration Anaerobic respiration 2 types: 1. ALCOHOLIC FERMENTATION = – In yeast cells • C6H12O6alcohol + CO2+2ATP 2. LACTIC ACID FERMENTATION = – In your muscles, when oxygen is not available • C6H12O6 lactic acid + 2ATP Let’s summarize… 1. Explain why the process of respiration is so important. 2. Explain the difference between the two types of respiration. 3. What nutrient is used in both types of respiration? 4. Which type of respiration is more efficient? Which statement is not a part of the cell theory? (1) Cells are the basic unit of structure of living things. (2) Cells are the basic unit of function of living things. (3) Cell parts such as chloroplasts are selfreplicating. (4) Cells come from preexisting cells. Which structure permits the entry and exit of materials in an animal cell? 1. lysosome 2. chromosome 3. cell wall 4. cell membrane The structure most closely associated with the destruction of worn out cell organelles is the 1. lysosome 2. centrosome 3. vacuole 4. chromosome Whitney observes a cell under the microscope. She identifies it as a green plant cell and not a cheek cell because of a (1.) nucleus (2.) cell membrane (3.) cell wall (4.) mitochondrion Which structure is found ONLY in animal cells? (1.) cell wall (2.) vacuoles (3.) centrioles (4.) chloroplasts The organelle most closely associated with the manufacture of proteins within the cell is the (1.) ribosome (2.) nucleolus (3.) cell wall (4.) cell membrane Review: 1. Yeast cells undergoing anaerobic respiration produce carbon dioxide and (1.) water (2.) ethyl alcohol (3.) nitrogen (4.) glucose 2. During the process of respiration, energy from the oxidation of glucose is stored in molecules of (1.) DNA (2.) ADP (3.) ATP (4.) RNA 3. In the presence of oxygen, _____ molecules of ATP can be formed. (1.)2 (2.) 19 (3.) 36 (4.) 63 4. Which process yields lactic acid and small amounts of usable energy? (1.) photosynthesis (2.) aerobic respiration (3.) anaerobic respiration (4.) chemosynthesis 5. The net yield of ATP from the process of fermentation is (1.) 2 (2.) 4 (3.) 34 (4.) 36 6. Muscles cells engaged in vigorous activity build up relatively high concentrations of (1.) lactic acid (2.) pyruvic acid (3.) alcohol (4.) oxygen 7. Where do the final stages of cellular respiration appear to take place? (1.) along the endoplasmic reticulum (2.) in the cytoplasm (3.) on the surface of ribosomes (4.) within the mitochondria 8. Aerobic respiration and fermentation are similar in that BOTH processes (1.) require oxygen (2.) use light energy (3.) release energy (4.) produce glucose 9. During aerobic respiration, the chemical energy of a glucose molecule is gradually released, producing 36 ATP and (1.) NH3 and O2 (2.) NH3 and CO2 (3.) H2O and O2 (4.) H20 and CO2
