Question 1

ATP is generated when protons flow through the cytochrome complex in the thylakoid membrane.

Accepted Answer

ATP is generated when protons flow through ATP synthase in the thylakoid membrane, not through the cytochrome complex.

Question 2

                        Premises: Phosphorylates PGA

Accepted Answer

The Answer of ATP and RuBP and G3P and Rubisco is...

Question 3

At a plant's light compensation point the rate of photosynthesis is greater than the rate of respiration. 
 
 ​

Accepted Answer

At a plant's light compensation point, the rate of photosynthesis equals the rate of respiration, meaning the plant's energy output and input are balanced.

Question 4

Match between columns Premises: Functions as a CO₂-acceptor molecule

Accepted Answer

The Answer of ATP and G3P and RuBP and Rubisco is...

Question 5

Match between columns
                        Premises: Catalyzes the "fixation" of carbon dioxide

Accepted Answer

The Answer of G3P and ATP and Rubisco and RuBP is...

Question 6

Photorespiration is a wasteful process that could be largely avoided if rubisco would bind only CO₂.

Accepted Answer

Photorespiration occurs when rubisco binds to O2 instead of CO2, leading to a less efficient process that consumes energy and releases CO2, thus reducing photosynthetic efficiency. If rubisco only bound to CO2, this wasteful process could be minimized.

Question 7

Match between columns
                        Premises: Two of these molecules leave the Calvin cycle and react, forming glucose or fructose.

Accepted Answer

The Answer of Rubisco and RuBP and G3P and ATP is...

Question 8

Most plants are known as photoheterotrophs.

Accepted Answer

Most plants are known as photoautotrophs because they use light energy to synthesize their own food from carbon dioxide and water.

Question 9

Question 10

Propose an appropriate solvent to be used in the extraction of photosynthetic pigments from chloroplasts. Explain your choice.

Accepted Answer

The answer of Propose an appropriate solvent to be used...

Question 11

Cyclic electron transport is different from noncyclic electron transport in that cyclic electron transport produces NADPH.

Accepted Answer

Cyclic electron transport produces ATP but not NADPH, whereas noncyclic electron transport results in the production of both ATP and NADPH.

Question 12

Question 13

Photosynthesis and aerobic respiration are both important processes for the generation of energy in organisms. However, the two processes are distinct. Explain the differences and similarities between the two processes.

Accepted Answer

The answer of Photosynthesis and aerobic respiration are both important...

Question 14

When photosynthetic pigments are extracted from the chloroplasts of green plants, they have a higher tendency to fluoresce than pigments within intact chloroplasts. Explain this phenomenon.

Accepted Answer

The answer of When photosynthetic pigments are extracted from the...

Question 15

CAM plants open their stomata at night, admitting CO₂ while minimizing water loss.

Accepted Answer

CAM plants open their stomata at night to admit CO2 while minimizing water loss, which is then fixed into organic acids and stored until daylight for photosynthesis, allowing them to thrive in arid conditions.

Question 16
