Biology-photosynthes
| Question | Answer |
|---|---|
| What is an autotroph | A plant or other organism that can make its own food |
| What is a heterotroph | Organisms that cannot make their own food |
| What does ATP stand for | Adenosine triphosphate |
| One of the main chemical compounds that sells used to store and release chemical energy only a few seconds of activity | ATP |
| What does ADP stand | Adenosine diphosphate |
| Low energy molecule that can be converted to ATP, Takeaway one phosphate | ADP |
| What is photosynthesis | Converts light energy into chemical energy, nourishes the entire living room |
| What is a pigment | Any substance that absorbs light |
| What is chlorophyll | A green pigment required for photosynthesis, the principal pigment in plants |
| The light dependent reactions of photosynthesis takes place here in the membranes of chloroplast , Light reaction | Thylakoids |
| Series of light absorbing pigment and proteins that capture and transfer energy in the thylakoids membrane | Photosystem |
| Where the light independent reactions occur, the region of The chloroplast in which the Calvin cycle occurs, dark reactions | Stroma |
| The stacks of thylakoids embedded in the stroma of the Chloroplast | Granum |
| Part of photosynthesis that absorbs energy from sunlight and transfers energy to the light independent reactions | Light dependent reactions |
| And enzyme that catalyzes the reaction that adds a high-energy phosphate group to ADP to form ATP | ATP synthase |
| Series of protons in the thylakoid and Michael Condrey a membranes that aid in converting ADP to ATP by transferring electrons | Electron transport chain |
| The stage of photosynthesis that uses ATP and NADPH to form a high-energy sugars or the dark reaction | Calvin cycle |
| Define photosynthesis in its simplest form | When plants or producers take energy from the sun to make food. The purpose is the give food to the producers who don't eat anything to provide for the rest of the system |
| Describe the importance of photosynthesis using autotroph and producer | It is important because autotroph's use it to make their own food, and producers use photosynthesis to then they produce for all the other living things we need plants are survive in plants use photosynthesis |
| Write the equation for photosynthesis | 6CO2 + 6H2O ---------> (light ) 6O2 + C6H12O6 |
| What are the reactants and products of the photosynthesis equation | The reactants are right, water, carbon dioxide The products are oxygen, glucose(sugar) |
| Why is Chloroplast important | It works to convert light energy of the sun into sugar/glucose that can be used by cells |
| What is chloroplast | Parts of the cell that contains pigment of all colors except green |
| Where are chloroplasts found within a leaf | They are found within the cells of a leaf |
| Draw and label the structures that make up a chloroplast Know: Stroma, thylakoids , granum , membranes | |
| What steps of photosynthesis take place and what structures of the chloroplast | 1. Inside the thylakoid membrane - light reactions - electron transport chain -Chemiosmosis 2. Inside the stroma - Dark reactions -Calvin cycle |
| Explain the steps of Photosynth | Energy from the sun goes into the thylakoid.it breaks down water molecules and releases oxygen, waste product,energy is carried along the membrane and made into ATP.energy is used to combine CO2 molecules into larger molecules of glucose stored as energy |
| What does the electron transport chain use the energy from light for | To convert it into a chemical bond Energy in the form of ATP and NADPH |
| How is the concentration H+ used to produce ATP in chemiosmosis | The energy from the concentration of hydrogen ions across the thylakoid membrane is used to create ATP and Chemiosmosis. When the hydrogen ions flow through the ATP synthesis to make ATP by adding phosphate group to ADP |
| What does light dependent reactions need | Light, H2O, ADP+P , NADPH |
| What does the light dependent reactions produce | 02, ATP, NADPH |
| What is a waste product of photosynthesis | Oxygen |
| What does dark reaction need it or light independent reactions need | CO2, ATP, NADPH |
| What does a duck reaction or the Calvin cycle make | Glucose |
| What's another name for the dark reaction | Calvin cycle |
| What is the goal of the Calvin cycle | To convert carbon dioxide into sugar/glucose To convert ATP and NADPH into NADP+and ADP+p |
| What are light dependent reactions | Reactions that need the suns energy to react/do job for Calvin cycle |
| Compare a battery to how energy is stored in released from ATP | A battery has a lot of long-term energy that is slowly give off. ATP has short term energy and when it gives off energy it's all at once for a few seconds, like a fully charged battery being used all at once |
| What are the three parts of ATP molecule | 1. Adenine or nitrogen base 2. Ribose - 5 carbon sugar 3. 3 phosphate |
| Draw a ATP molecule | |
| How is energy released from ATP molecule | ATP releases energy when a phosphate group breaks off, then converts to ADP |
| How is ATP formed from ADP | ADP is formed when you cut off a phosphate group/breaks off from ATP and you just add a phosphate to get ATP |
| Compare the amount of energy stored in ATP and glucose. Which is used by the cell for immediate source of energy | A single glucose has more than 90 times the energy ATP has but ATP can transfer energy very fast so ATP is used by the cell as immediate source of energy |
| What role do plant pigments play in the process of photosynthesis | They are important because they absorb the light that is then transferred into energy to photosynthesis needs pigments for it to happen |
| How do you not get energy from directly eating food | The food you eat does not have a TP that your cells use, first they must be digested which breaks the food down into small molecules that can be used to make ATP |
| Why are the dark reactions dependent on the light reaction | Dark reactions use ATP and NADPH to make energy molecules and light reactions use the sunlight to make ATP and NADPH for the dark reactions |
| Why do the cells of plant roots generally like Chloroplast | They lack chloroplast because they usually need sunlight to develop and roots are not where the sun is. Also chloroplast are mainly used for capturing light |
| Why do leaves of plants appear to be green | They appear green because they absorb all the other colors like Violet, blue, light yellow, orange and red |
| How do heterotrophs get their energy from the sun even though they cannot make their own food | They get their energy from the sun by eating other things that get their energy from the sun example plant |
| What is the advantage for a plant to have more than one kind of pigment | They can take in light from different wavelengths of light and absorb more light to make more chloroplast |
| What three factors can affect the rate of photosynthesis | 1. Water Shortage 2. Temperature 3. Light intensity 4. Very where but sometimes carbon dioxide |
| Explain why water can affect the rate of photosynthesis | Without water the plant will die, slows down photosynthesis |
| Explain how temperature can affect the rate of photosynthesis | Photosynthesis is best between 32 and 90°F the letter synthesis will rapidly decrease at either extremes, will go faster when warm, but too warm or too cold then what is synthesis will not run |
| Explain how light intensity can affect the rate of photosynthesis | The more light the more photosynthesis happening there is a rate where it's going as fast as it can |
| What do all living things need and where does it come from | All living things need energy and it comes from the sun |
| When ATP uses all its energy what does it become | ADP |
| The cell only makes a little ATP for the time it needs it because it's what | Has very poor Long-term storage |
| Cells make ATP as needed through | Photosynthesis or cellular respiration |
| What does oxygen leave through | Stoma |
| Sac like photonthetic membrane contains clusters of chlorophyll pigment and protein that abosorbes light energy | Thylakoid |
| Space/gel like solution outside thylakoids. Calvin cycle occurs here | Stroma |
| Where does the oxygen come from in the cycle | From H2O being split |
| What does a hill like shape/upside down U on a graph represent | The temperature |
| What does a steady line going up and then levels out to a constant rate on a graph represent | The light intensity going to it's max and then staying consistent |
| What happens to carbon dioxide in the photosynthesis process | It is broken down in the Calvin cycle/dark reactance |
| What happens to the H2O in the photosynthesis process | It's split in the ETC into H+ to make ATP or NADPH for energy OR ... releases O2 releases stoma |
| What happens to glucose in photosynthesis process | Produced in the Calvin cycle |
| What happens to oxygen in the photosynthesis cycle | Produced in the ETC |
| What is the cellular respiration equation | C6H12O6 + 6O2 ----> 6H2 + 6CO2 + ATP |
| What color is completely absorbed and nothing reflected | Black |
| What does white light contain | All colors |
| When something appears white what is happening | All the colors are being reflected and nothing is being absorbed |
| What are the two types of chlorophyll | Chlorophyll a Chlorophyll b |
| What is energy stored | Glucose |
| Draw a chloroplast cell |
