Chapter 8 Photosynthesis

Which of the following components is not used by both plants and cyanobacteria to carry out photosynthesis?

chloroplasts

What two main products result from photosynthesis?

sugars/carbohydrates and oxygen

In which compartment of the plant cell do the light-independent reactions of photosynthesis take place?

stroma

Which statement about thylakoids in eukaryotes is not correct?

Thylakoids exist as a maze of folded membranes

Predict the end result if a chloroplast's light-independent enzymes developed a mutation that prevented them from activating in response to light.

ATP and NADPH accumulation

How are the NADPH and GA3P molecules made during photosynthesis similar?

They both store energy in chemical bonds.

Which of the following structures is not a component of a photosystem?

ATP synthase

How many photons does it take to fully reduce one molecule of NADP+ to NADPH?

2

Which complex is not involved in the establishment of conditions for ATP synthesis?

photosystem II

From which component of the light-dependent reactions does NADPH form most directly?

photosystem I

Which molecule must enter the Calvin cycle continually for the light-independent reactions to take place?

CO2

Where in eukaryotic cells does the Calvin cycle take place?

chloroplast stroma

Which statement correctly describes carbon fixation

the conversion of CO2 into an organic compound

If four molecules of carbon dioxide enter the Calvin cycle (four "turns" of the cycle), how many G3P molecules are produced and how many are exported?

8 G3P made, 1 G3P exported
