AP Biology Chapter 6,7,8 Test

AP - Compare and Contrast the Electron Transport Chains of Cellular Respiration and Photosynthesis. (when/where they occur)

• It occurs in the second step of Photosynthesis and the first step of Cellular Respiration.

• It occurs in the first step of Photosynthesis and the third step of Cellular Respiration.

• It occurs in the third step of Photosynthesis but not at all in Cellular Respiration.

• It does not occur in Photosynthesis but is the third step of Cellular Respiration.

AP - Trace the pathway of a glucose molecule in the first two steps of Cell Respiration. (how it changes throughout the process)

• Glucose → Pyruvate → Acetyl CoA

• Glucose → ATP → Pyruvate

• Glucose → NADPH → Acetyl CoA

• Glucose → H2O → ATP

AP - All of these pairings are correct except:

• Endergonic - Photosynthesis

• Anabolic - Cellular Respiration

• Exergonic - Cellular Respiration

• Both A and C are incorrect

AP - What would happen if you placed an enzyme in the chemical reaction?

• The reaction would occur slower than without it.

• Energy would be stored, not released.

• Activation energy would decrease.

• The products would become the reactants.

AP - Determine why plants appear green when placed under white light.

• The chlorophyll absorbs green wavelengths but reflects the others.

• The white light is really green but appears white to the eye.

• Green wavelengths are reflected by the chlorophyll and the others are absorbed.

• The plant reflects blue and yellow light but appears to be green.

AP - Based on the picture, what is the second step called (the enzyme hugging the substrate)?

• Activation energy

• Induced fit

• Binding site

• Both A and B

DH - If the Co2 levels in your body were cut off, predict which of the following processes would fail to function correctly.

• Calvin cycle

• Glycolysis

• Electron transport chain

• Both A and B

DH - Using the two processes photosynthesis and cellular respiration, all of the following require oxygen except

• Glycolysis

• Fermentation

• Electron Transport Chain

• Both A and B

DH - According to the graph below, determine which of the following experiments accurately represents a plant’s absorption under different wavelengths.

• Putting a cabbage plant under green light makes the tallest plant

• Putting a cabbage plant under blue or orange light makes the tallest plant

• Putting a cabbage plant under blue or orange light makes the shortest plant

• Putting a cabbage plant under a red light makes the tallest plant

DH - According to the graph, predict why does Enzyme ChesAdams and Enzyme GlenKeppie’s rate of reaction suddenly drop at temperatures 43℃ and 76℃

• Both the enzymes denature and lose their shape, therefore they slow down

• Most enzymes cannot work past these temperatures because the conditions get too moist

• The enzyme’s leave the cell after a certain temperature

• None of the above
