Bio Unit 8

QuestionAnswer
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. Carbon dioxide depletion
How are the NADPH and G3P molecules made during photosynthesis similar? They are both end products of photosynthesis.
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? 8
Which complex is not involved in the establishment of conditions for ATP synthesis? cytochrome complex
From which component of the light-dependent reactions does NADPH form most directly? photosystem I A C B
Plants containing only chlorophyll b are exposed to radiation with the following wavelengths: 10nm (x-rays), 450nm (blue light), 670nm (red light), and 800nm (infrared light). Which plants harness the most energy for photosynthesis? Blue light irradiated plants
Which molecule must enter the Calvin cycle continually for the light-independent reactions to take place? CO2
Which order of molecular conversions is correct for the Calvin cycle? RuBP + CO2 → [RuBisCO] 3-PGA → G3P
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, 4 G3P exported

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
