How is the photic energy absorbed by chlorophyll transfered to ATP molecules in photophosphorylation? How will be the resulting ATP used?

How do C4 plants improve the efficiency of carbon fixation in the Calvin cycle? and What is the net product of the Calvin cycle - the energy input and the products.

What enzyme fixes CO2 in bundle sheath cell of chloroplasts in Calvin Cycle of C4 plants?

What special adaptation has evolved in CAM plants such as cacti and stonecrops that allows CO2 fixation and the Calvin cycle to occur in the same cell, but still occur separately? Briefly describe how this separation of events works.

Why is it necessary to lyse the chloroplasts? 1.DCPIP passes easily across the intact chloroplast membrane and the thylakoid membrane, so electron transport could not be reliably measured 2.DCPIP passes easily across the intact chloroplast membrane, but can't get into the thylakoid, so electron transport could not be reliably measured 3.DCPIP cannot easily pass across the intact chloroplast membrane, so electron transport across the thylakoid membrane could not be reliably measured

Identify the chemical basis for ApH and AY across the chloroplast thylakoid membrane by dragging the descriptions to their targets. Be sure to notice that the upper arrow iindicates ApH and the lower arrow indicates ΔΨ.

What happens during the regeneration stage of the Calvin Cycle? Energy from ATP and electrons from NADPH are used to reduc 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose) The remaining G3P molecules that have not exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue Oxygen is produced through this process The enzyme Rubisco attaches to CO2 to RuBP, causing the formation of molecules of 3-phosphoglycerate

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

What percentage of photosyntheticallyactive radiation is captured by plants?

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
