The diagram below represents a diver s motion from the top of a high diving board into a pool of water

Please label the image to demonstrate your understanding of the Krebs cycle 6 Citrate Pyruvate Acetyl COA CO Oxaloacetate ATP 2 Enter your search term Total Yields Per Glu C ATPS NADHS CO

savings account is used to save money for use at a later date The account owner deposits money in the ccount when they have money that is not needed immediately and they can withdraw money for use a ometime in the future the flow of energy through photosynthesis and respiration were compared to maintaining a savings account which would be accurate A C D Both photosynthesis and respiration are like making an energy deposit Both photosy in are like making an energy withdrawal Photosynthesis is like making an energy deposit and respiration is like making an energy withdrawal Photosynthesis is like making an energy withdrawal and respiration is like making an energy deposit

You engineer a plant that produces the absorbance spectrum as shown At what wavelengths is this plant performing photosynthesis Please choose all that a Absorbance vs Wavelength 0 6 Absorbance 0 4 0 2 0 400 400 600 700 nm 400 500 nm 500 600 nm 700 nm 500 Wavelength 600 500 600 Wavelength of light nm 700 700

Why do plants appear green O Their pigment molecules absorb green wavelength lights in order to perform photosynthesis O They contain large amounts of green fluorescent protein O Their photosystems produce green wavelength light as a result of electrons releasing energy via fluorescence O Their chlorophyll molecules absorb red and blue wavelength light but reflect green wavelength light

Which statement about the Calvin Benson cycle is incorrect Rubisco catalyzes the reaction between CO2 and RuBP For each turn of the Calvin Benson cycle only 2 molecules of G3P go on to make glucose 6 RuBP is reformed by 10 G3P molecules ATP and NADPH form when 3PG is reduced

Question 13 Write only one of the Suffixes that means process

Once produced NO can diffuse to neighboring cells True False

Cytochrome b6 f is a multi protein complex that has multiple functions Which of the following is NOT a function of the cytochrome b6 f complex O exists in the thylakoid membrane All of these answers are functions of the cytochrome b f complex O the two PQH2 traverse different paths within the complex O receives e from PQH2 and Fd O Cytochrome b participates in cyclinc e flow while cytochrome f participates in non cyclic e flow

In the citric acid cycle the reduction of NAD to NADH is coupled to the generation of CO2 and the formation a high energy thioester bond in step 4 This energy from the thioester bond is use in step 5 for what purpose Oto generate a molecule of GTP Oto generate a molecule of ATP to generate a proton gradient to generate a molecule of NADH

For this assignment you will develop a scientific model on a poster that illustrates the role of photosynthesis and cellular respiration in the carbon cycle Your model should also show how carbon cycles the Earth s four spheres Once you have completed your model you will write a paper with sever paragraphs describing the content of your model in more detail

Electrons that move through the photosynthetic electron transport sequence are all derived from water through the action of the oxygen evolving complex True False

Glyceraldehyde 3 phosphate dehydrogenase donates the hydride to O oxygen O acetyl COA O NAD O FADH

When temperatures rise plants loss O close their stomata O take in excess CO2 O do nothing in particular O None of the available answers are correct open their stomata to prevent H O

Activity C The carbon oxygen balance Get the Gizmo ready Click Reset Clear all of the test tubes Turn the light switch to on Check Show oxygen and CO values Question How are the amounts of oxygen and carbon dioxide related to each other 1 Observe Put two Elodea sprigs into a test tube Put the O CO probe into the tube with the Elodea Click Play As the Gizmo runs Pause it a few times C A How do the oxygen O and carbon dioxide CO levels change over time B What is always true about the total amount of O and CO in the test tube What happens when the CO reaches zero 2 Revise and repeat Click Reset Remove the plants Repeat the experiment with two snails A How do the gas levels change What is the total of 0 and CO 2 0 CO

hits and animals depend on each other 1 Observe Put one sprig of Elodea and one snail in a test tube with the lights on Click Play A Does the color of the water in the tube change B What happens to the O and CO levels 2 Predict Without using the Gizmo predict what you think will happen to the gas levels in each case liste below Leave the Actual result column blank for now Tube 2 snails 2 sprigs lights on 1 snail 2 sprigs lights on 1 snail 2 sprigs lights off Prediction 1 Actual result 3 Run Gizmo Now run the Gizmo to test your predictions Record your findings in the table 4 Generalize Describe how plants and animals each contribute to the survival of the other This type of cooperative relationship is called interdependence
