11/8 - Pearson Unit 3 cycles

for the beginning of this plant cycle, __ provides energy for __ which occurs in __

sunlight, photosynthesis, chloroplasts

chloroplasts contain the pigment

clorophyll

photosynthesis produces

oxygen and sugar (C6H1202)

oxygen and sugar in photosynthesis are inputs for 

cellular respiration 

cellular respiration occurs in the 

mitochondria 

cellular respiration produces

carbon dioxide and ATP

carbon dioxid provides __ for __

carbon, photosynthesis

what wavelength is best absorbed by chlorophyll a?

435 nm

What wavelength is best absorbed by chlorophyll b?

455 nm

Why do carotenoids appear yellow and orange?

They absorb blue/green light and reflect yellow and red wavelengths of light

What role does chlorophyll b and carotenoids play in photosynthesis?

These pigments are able to absorb more wavelengths than just chlorophyll a. They simply broaden the wavelength of light

Photosynthetic membranes are found in the __ in plant cells

chloroplasts

What are products of light reactions of photosynthesis that are utilized in the Calvin cycle? 

ATP and NADPH 

What is the summary of the redox reaction that occurs in photosynthesis?

CO2 is reduced to form glucose 

What is the process that relates to chemiosmosis in chloroplasts?

the establishment of a proton gradient across the thylakoid membrane

Photophosphorylation in photosynthesis is most similar to what processes associated with cellular respiration 

oxidative phosphorylation in mitochondria 

P680+ is necessary because

It obtains electrons from the oxygen atom in a water molecule, so it must have greater affinity to electrons than oxygen has 

What are the 4 cycles of the Calvin Cycle from beginning to end?

Carbon fixation, reduction, release of one G3P, and lastly regeneration of RuBP

What comes in during carbon fixation to make what? 

CO2 and 6 3-PGA → used for the cycle

What is 3-PGA composed of?

3 carbon and 1 phosphate

What is produced during reduction?

6 ATP, 6 ADP+P, 6 NADPH, 6 NADP+

What is produced after reduction and is used for the cycle?

6 GP3

What is released after the formation of 6 G3P

1 G3P → used for the cycle

What is continued into the cycle after 1 G3P is released?

5 G3P

What stage is right after 5 G3P is continued into the cycle?

regeneration of RuBP

What is released during the regeneration of RuBP

3 ATP and 3 ADP

What composes RuBP

5 carbon and 2 phosphate ends

What is there at the end of the cycle Calvin cycle?

rubisco

the overall process of the Calvin cycle is

making sugar

Which metabolic pathways produces reduced soluble electron carriers?

both the light reactions of photosynthesis and the citric acid cycle

What is an accurate comparison of C3 and C4 plants?

C4 plants can continue to fix CO2 even at relatively low CO2 concentrations and high oxygen concentrations, whereas CO3 plants cannot

In C3 plants the conservation of water promotes photor
