|Question |
|Answer |
| |
|Energy Questions (4.1) |
|Why do organisms need energy? (give three reasons) |Active transport |
| |Cell growth |
| |Cell division |
| |Making macromolecules |
|What do you call an organism that can make its own food? |Autotroph |
|What do you call an organism that consumes other organisms for energy? |Heterotroph |
|What is the ultimate source of energy for life on earth? |The sun |
|What molecule do cells use for energy? |ATP |
|What do the letters above stand for? |Adenosine Tri Phosphate |
|When you break phosphates off of ATP, what gets released? |Energy |
|Which food molecules are most frequently broken down by your cells for |Carbohydrates |
|energy? | |
|What is the name for the process that uses chemicals as an energy source |Chemosynthesis |
|(instead of sunlight) to build sugars? | |
|Photosynthesis Questions (4.2) |
| The conversion of solar energy into chemical energy in the form of organic|photosynthesis |
|compounds (like glucose). | |
| What is the overall reaction of photosynthesis? |6CO2 + 6H2O ( C6H12O6 + 6O2 |
|Where in a cell does photosynthesis take place? |chloroplasts |
| What are the reactants (raw materials) of photosynthesis? |Carbon dioxide & water |
|What are the products of photosynthesis? |Glucose & oxygen |
| This pigment molecule has the role of absorbing light energy during |Chlorophyll |
|photosynthesis. Where does this molecule “live”? | |
| |Thylakoid membranes |
| Why is chlorophyll green (and thus why plants are green)? |Can’t absorb green light, so it reflects green light |
| What is the major atmospheric product (gas in the atmosphere) of |oxygen |
|photosynthesis? | |
| What is the original source of the oxygen produced? (what molecule is |water |
|broken down to release oxygen) | |
| What three environmental factors can affect the rate of photosynthesis? |Light, temperature, pH, CO2 Levels |
| | |
| | |
| Where in a cell does photosynthesis take place? |chloroplasts |
|What are the two stages of photosynthesis? |Light-dependent reactions |
| |Light-independent reactions (Calvin cycle) |
|Which stage converts captured light energy into chemical energy? |Light-dependent Reactions |
|Which stage splits water, releasing oxygen gas as a product? |Light-dependent Reactions |
| These are the disk-shaped structures inside of a chloroplast where the |Thylakoid Membranes |
|light-dependent reactions take place? | |
|Which stage of photosynthesis produces carbohydrate molecules using energy |Light-independent reactions (Calvin cycle) |
|(ATP) from the light reactions? | |
|Molecules of what gas are used (“fixed”) to create sugars? |Carbon dioxide |
| Fluid inside of chloroplasts where the Calvin Cycle take place? |Stroma |
|What happens to the sugars that get produced in photosynthesis? |They can be used by the plant (or organisms that eat plant |
| |cells) in cellular respiration |
|Cellular Respiration Questions (4.4 & 4.6) |
|What is the overall reaction for cellular respiration? |C6H12O6 + 6O2 ( 6CO2 + 6H2O+ ATP |
| |Glucose + oxygen ( carbon dioxide + water + ATP (cellular |
| |energy) |
|This process breaks down food molecules (like sugars) to release stored |Cellular Respiration |
|energy in the form of ATP. | |
|What are the reactants (raw materials) for cellular respiration? |Glucose and oxygen |
|What are the products of cellular respiration? |Carbon dioxide and water |
|What are the two types of respiration? |Aerobic & anaerobic |
| | |
|What is different in the two types you answered for #33? |Aerobic occurs when oxygen is present, anaerobic occurs when |
| |oxygen is absent |
|Which process, aerobic or anaerobic respiration produces more ATP per |Aerobic |
|molecule of glucose burned? | |
|What are the 3 stages of aerobic respiration? |Glycolysis |
| |Krebs Cycle |
| |Electron Transport |
| During glycolysis, glucose is broken down, producing 2 ATP’s and two |pyruvate |
|molecules of what? | |
|What is the first step of either anaerobic or aerobic respiration where |Glycolysis |
|glucose is “broken” down? | |
|Where in a cell does cellular respiration take place? |mitochondria |
|Which stage of cellular respiration produces the most ATP? |Electron transport |
| What is another name for anaerobic respiration? (when organic molecules |Fermentation |
|are broken down in the absence of oxygen) | |
|What are the two types of fermentation, and who does them? |Lactic acid fermentation done by human and bacterial cells |
| |Alcoholic fermentation by yeast and plant cells |
| What substance causes your muscles to “burn” after substantial exercise |Lactic acid |
|because they do not have sufficient oxygen? | |
| How are photosynthesis and respiration related as a cycle? |The products of one are the reactants of the other |
