f chlorophyll is extracted from plant cells and exposed to light, it absorbs light energy momentarily and this energy is almost immediately reradiated as light. Thus chlorophyll molecules can not cause photosynthesis by themselves. Why? What is required for pho

Complete the following table to compare the electron-transport phase of cellular respiration with the light-dependent reactions of photosynthesis.

How does light color affect the rate of photosynthesis?  Why does the color of light matter?      Clear Red Green Blue Number of Bubbles  (1 Min) 6 12 6 15

Is it correct to consider water decomposition by the action of light the basis of the photosynthesis process?

Which of the following lists the stages of the Calvin cycle in order, starting with the stage where carbon dioxide is added? PGAL synthesis → carbon fixation → light reactions → regeneration of RuBP carbon fixation → PGAL synthesis → regeneration of RuBP regeneration of RuBP → carbon fixation → PGAL synthesis photorespiration → PGAL synthesis → regeneration of RuBP → carbon fixation

Adjusting the wavelength of light and increasing the temperature can increase the rate of photosynthesis. Using specifics, describe in detail the effect of wavelength and temperature on photosynthesis and why or how these 2 factors affect the creation of the molecules used in or produced by photosynthesis.

What happens during the carbon fixation stage of the Calvin Cycle (light-indepedent reactions)? Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose) Oxygen is produced through this process The remaining G3P molecules that have exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue. The enzyme Rubisco attaches to RuBP, causing the formation of molecules of 3-phosphoglycerate

The most important result of the light-independent (or Calvin Cycle) reactions is: ??? the addition of phosphate to sugar to form sugar-phosphate the synthesis of sugar from CO2 the change of chlorophyll from green to colorless the transfer of electrons to glucose molecules the rearrangement of sugar molecules to form O2 from H2O

Which of the following correctly sequences the steps of non-cyclic electron transport?    a) Chlorophyll molecules absorb UV radiation exciting electrons which flow through photosystem I, returning to the chlorophyll molecules b) Electrons donated from water molecules pass through photosystem I then photosystem II before returning to the chlorophyll molecules, generating ATP in the process c) Water is oxidized by the capture of light energy; these excited electrons are passed through the dark reactions, returning to chlorophyll during the final light reactions d) The ATP and NADPH generated by the reactions of photosystem II and photosystem I are utilized by the Calvin Cycle to build high energy glucose molecules

As energy passes from blue-absorbing chlorophylls down to red-absorbing chlorophylls, surprisingly, no energy passes from lower energy-absorbing pigments back to higher ones (in other words, the process is irreversible). Why might that be?
