Cell Respiration and Photosynthesis (30 questions)

What are two reactants (substrates ) used to make ATP?

ADP + Pi

What is the energy made during cell respiration?

ATP

What are the end products of the light reactions?

ATP, NADPH, O2

What plants use only the calvin cycle

C3 plants

Which type of plant closes its stomata in the day and stores CO2 in the night in the form of mallic acid: (C3, C4, or CAM)?

C3closes its stomata.

What is the end product of the dark reaction?

C6, H12, O6

What plants store carbon into a 4C compound?

CAM plants

In the previous question, which represents a reduction?

CO ---> C6H12O6

Which of the following represents oxidation?

CO2 ---> 2H+O2

When plants close stomata what gas increases and what happens to photosynthesis

CO2 level decreases causing photosynthesis to stop. Increase O2 level. If the O2 level is greater than the level of CO2 photorespiration occurs. They lose the CO2 they just fixed

How is photosynthesis related to global warming

Cellular respiration uses oxygen and releases carbon dioxide. During global warming, the amounts of carbon dioxide increase. Plants use carbon dioxide from the atmosphere by using photosynthesis.

Based on the mode of photosynthesis, what type of plant is corn: (C3, C4 or CAM)?

Corn is C4

T or F a pH value higher than the optimum will increase photosynthesis?

False

What are the end products of photosynthesis?

Glucose and O2

What color of light is not absorbed, but is reflected by plants?

Green

What causes plants to close their stomata

Heat during the day

The final electron acceptor of photosynthesis is

NADPH

The final electron acceptor of cell respiration is

Oxygen

Whats made in PSI verses PSII

PSI is the main function of ATP, Generates NADPH. PSII main function are ATP synthesis and hydrolysis of water. It oxidizes water and transfers electrons to PSI.

What is used by plants to harvest light?

Pigments

Which are primary vs accessory pigments

Primary pigments harvest the majority of the light. The green pigments called "Chlorophyll". Prefer red (600-700nm) and blue (400-500nm). Accessory pigments. Non-chlorophylls. Harvest other wavelengths (colors) of light. Protect plant and chlorophylls from harmful light.

What is the source of energy for photosynthesis?

Water, carbon dioxide, and light

Name the phase of either cell respiration or photosynthesis in which each of the following occurs

a. H2O ---> 2H+O2 b. CO2 --> C6H12O6 c. Glucose ---> Pyruvate d. C6H12O6 ---> CO2 e. Making ATP using NADH

Where do the following reactions occur?

a. H2O ---> 2H+O2 b. CO2---> C6H12O6 c. Glucose ---> Pyruvate (Glycolysis) d. C6H12O6 ---> CO2 e. Fermentation (cytoplasm) f. Making ATP using NADH g. Where gas exchange occurs in plants (leaves/stomata) h. making NADPH and ATP (light reactions)

Is photosynthesis endergonic or exergonic?

endergonic

Is cell respiration endergonic and exergonic?

exergonic
