Biology (photo/resp)
photosynethesis and respiration chapter 8-9
| Question | Answer |
|---|---|
| what is the final electron acceptor in the ETC | oxygen |
| where did the final electron acceptor come from in the ETC ( what molecule is responsible for brinnging it to this molecule) | The hydrogen molecule is responsivle for bringing it to that molecule form within the mitochondria |
| can a cell undergo both cellular respiration and fermentaion at the same time? | No, because respiration occurs in the presence of oxygen while fermantaion does not require oxygen |
| what is the name of the molecule that acts to synthesize ATP? | atp synthase, this is an enzyme |
| where does photosynhthesis occur? | chloroplast |
| where do light dependent reactions occur | inner thylakoid membrane |
| where does light independent reacdtions occur?antoher name for this reaction | stroma, calvin cycle |
| where does cellular respiration occur? oxygen? | mitochondria, yes |
| where does glycolysis occur? oxygen? type of cell? | cytoplasm, no, all living things with cells |
| where does the krebs cycle occur, what is another name for krebs cycle, does it require oxygen, what type of cell does it occur in? | mitochondira matrixs, citric acid, yes, eukarotes |
| whre does ETC occur?oxygen?type of cell? | mitochondria inner membrane, yes, eukarotes |
| where does alcoholic fermentaion occur? oxygen? type of cells? | cytoplasm, no, yeast bacteria |
| whre does lactic acid fermentation occur? oxygen? type of cell? | cytoplasm, no, aukarotes( muscle/andimal) |
| whats another name for the calvin cycle | independent reactions |
| when does fermentaion occur | when there is no oxygen and it helps keep glycolysis continueing |
| why do you get sore so quickly after working our | beacuse lactic acid in your muscles build up quickly because theres no oxygen |
| formular for photosynthesis? | 6co2+6h20-->c6h12o6+6o2 |
| formula for respiration | c6h12o6+6o2-->6co2+6h2o |
| what are the 3 parts of ATP...what does it stand for...how do you get ADP from ATP | adenine, ribose(sugars) 3 phosphate groupds, adenosine triphosphate, adp is made when 1 phospate is taken away |
| what are the 3 factors tht affect the rate of photosynthesis? | Temperature, light intensity, amount of water |
| what is theh reason that plants appear to be green | Reflect green and absorb other colors |
| cells break down_______ through a series of chemical reactions | Glucose |
| is glycolysis anaerobic or areobic? | anaerobic |
| describe how photosynthese and respiration are connected? | the sunlight provides energy for phtosynthesis to occur which creates glucose and oxygen which is used by all cells in respiration which produces carbon dioxide which is taken by plants in photosynthesis.... |
| photosynthese is the process by which____ make food | plants |
| what comppound serves to transfer and store enefery for later use | glucose |
| what gas is released into the air as a result of photosynthesis? | oxygen |
| what inorganic substances are necessary for photosynthesis? | carbon dioxide and water |
| could photosynthesis occur on a cloudy day? | yes, if there is enough light energy for photosyntheis to continue |
| the energy for respiration comes from _________ or_____ | food or ATP |
| what are the products of repiration? | carbon dioxide and water |
| fermentaion is a form of ( photo..resp?)...why | respiration because both fermentaion and respiration produce carvon dioxide but photosynthesis uses it |
| whcih produces carbon dioxide gas? | respiration |
| glucose is formed in what ( photo or resp) | photosynthesis |
| chlorophyll is energized in what ( p or R) | photosynthesis |
| what is the sugar in ATP called? | ribose |
| _______ is the ability to do work?` | energy |
| energy cannot be______or________ it can only ____________ ________ | energy cannot be created or destroyed, it can only change forms |
| photosynthesis- products of a reaction have ____ energy than reactant....energy is gained in the form of_______ | products of the reaction have more energy than the reactants....energy is gained for sunlight |
| respiration_ products of the reaction have ______ energy than the reactants....energy is lost as _____or ____ect.... | products of the reaction ahve less energy than the reactants...energhy is lost as heat or growth ectt... |
| define photosynthesis | process by which plants and some other organisms use light and energy to convert water and carbon dioxide into glucose and oxygen |
| define respiration | the process that release energy by breaking down glucose in the presence of oxygen and converting it into carbon dioxide andw ater |
| name 3 steps of respiration ...( not glycolysis krebs ETC>..) | 1. production of ATP2. production of carbon dioxide3. production of water |
| all living things perform____________ | respiration |
| Chlorophyll A is a _______,______colorchlorphyll B is a _______,______ colorXanthophylls is a _______,_______colorcarotenes is a _______,_______color | chlorophyll a= blue greenchlorophyll b= yellow greenxanthophylls= yellowcarotenes= red or yellow |
| which pigment is thought to be the color of decomposition | xanthophylls |
| anaerobic= | no oxygen |
| aerobic= | oxygen required |
| 3 stages of cellular respiration | glycolysis, krebs cycle, ETC |
| in glycolysis a glucose molecule is broken down and changed into a ________ acid | Pyruvic acid |
| in the krebs cycle.....citric acid is broken down and releases _________ ________ at each step | carbon dioxide |
| as electrons are transpferred in the ETC, __________ions build up and create a chemical gradient( this gradient will cause the ions to diffuse to though the ATP | hyrogen ions |
| which is an enzyme that puts photphates on ADP to make ATP | atp synthase |
| final electon accept in the ETC is_________ | oxygen |
| what happens to oxygen after the ETC.... | combines with 2 hydrogen ions to form water |
| the break down of glucose without oxygen is ________ | fermentaion |
| when your muscles cells require energy at a faster rate than it can be supplied by aerobic respiration...they begin to carry out _______ ________ __________ | lactic acid fermentaion |
| does fermentaion need oxygen? | no |
| what are the end products of alcoholic fermentaion | ethyl alcohol and carbon dioxide |
| what 2 things carry out alcoholic fermentaion | bacteria and yeast |
| what process is this- occurs in organisms that use chemcials as the enrgy needed to make their own food ( unique to bacteria) | chemosynthesis |
| heterotrophs are also known as....... | consumers |
| energy is releasede for the cell to use when a bond between 2 photophate groups is ________ | broken |
| energy is stored for the cell to use when a phosphate group is ______ | created |
| when capturing the suns energy in photosynthesis..... it occurs in the ___in small disks called_______ which contain the pigment_______ | occurs int he chloroplast in small disks called thulakoids which contain the pigment chlorophyll |
| chlorophyll ______the energy from the sunlight | traps the energy |
| inthe thylakoid membrane....the energy is used to make _____ _____ whcih will ve used in the ____ ________ | energy is used to make atp molecules which wil be used in the calvin cycle |
| when making glucose in photosynthesis is occurs in the __ | stroma |

| what is another name for light independent reactions? | calvin cylcle |
| whcih molecules carry high energy electrons in photosyntheses? respiration? | photosynthesis- nadp+ carriersrespiration- nad+ and fad carriers |
| what enzyme is used to convery ADP to ATP | ATp synthase |
| is atp synthase only in photosyntheses, respiration, or both? | both |
| what type of organisms would not be able to carry out cellular respiration? | oranisms that do not have mitochrondria could not carry out all parts of cellular resperation cause they do not have membrane bond organells |
