Light Dependent Reactions in Photosynthesis

Question 1

Which corrections should be made to describe photosynthesis accurately? Check all that apply.

Revolt · Accepted Answer

A: (1) Light energy and chemical energy should be switched.; C: (3) Plants that contain chlorophyll should not be included.; E: (4) Animals and plants should be switched.

Question 2

Which row accurately represents photosynthesis when substituted into the equation?

Revolt · Accepted Answer

C: 3

Question 3

A scientist notices an increase in the glucose production in the plants he is studying. What are the possible reasons? Check all that apply.

Revolt · Accepted Answer

A: The plant was exposed to more intense light.; C: The plant absorbed more carbon dioxide.

Question 4

Which labels would correctly model photosynthesis?

Revolt · Accepted Answer

A:: Carbon dioxide; B:: Light energy; C:: Oxygen; D:: Glucose; E:: Water

Question 5

Which labels would correctly model photosynthesis?

Revolt · Accepted Answer

A: ✔ Carbon dioxide

Question 6

Which corrections would change the diagram to accurately model the light-dependent reaction of photosynthesis? Check all that apply.

Revolt · Accepted Answer

A: CO2 should be changed to H2O.; B: ADP and ATP need to be switched.; D: Chemical energy should be changed to light energy.

Question 7

Photosynthesis converts light energy to chemical energy.Which molecules are the end product of this transformation of energy in this reaction?

Revolt · Accepted Answer

C: ATP and NADPH

Question 8

What would happen if the electron transport system in the light-dependent reaction of photosynthesis was disabled for some reason?

Revolt · Accepted Answer

If the electron transport chain (ETC) were disabled, the plant would be unable to produce ATP and NADPH. Without these two energy-carrying molecules, the light-independent reactions (the Calvin cycle) could not take place, which means the plant would be unable to synthesize glucose. Ultimately, the plant would not be able to store energy or maintain its biological functions and would die.
