Describe the structure of a chloroplast.

Similar to a mitochondria in that it makes energy for cell, are contained in mesophyll cells.

Describe the Relationship between an action spectrum and an absorbtion spectrum

An action spectrum is a graph that profiles relative effectiveness of different wavelengths of radiation in a particular process, Absorbtion spectrums are when there is a visual representation on how well particular pigments absorb different wavelengths.

Describe the Similarities and differences between oxidative phosphorlation in mitochondria and photophosphorylation in chloroplasts.

IN OXIDATIVE PHOSPHORYLATION: high energy electrons dropped down the transport chain are extracted from organic molecules. Uses chemiosmosis to transfer chemical energy from food molecules to ATP. IN PHOTOPHOSPHORYLATION: source of electrons is water.

Describe the Similarities and differences between oxidative phosphorlation in mitochondria and photophosphorylation in chloroplasts.

Transform light energy to chemical energy in ATP. protons are pumped to intermembrane space and drive ATP synthesis as they diffuse.

Describe the role of ATP and NADPH in the Calvin cycle.

They convert CO2 into sugar. The cycle spends ATP as an energy source and consumes NADPH as reducing power for adding high energy electrons to make sugar.

Describe the major consequences of photorespiration.

It generates no ATP, it consumes ATP. It produces no sugar. It counteracts what normal plants do.

Describe two important photosynthetic adaptations that minimize photorespiration.

C4 photosynthesis plants incorporate CO2 into four carbon compounds in mesophyll cells using an enzyme called PEP carboxylase. CAM open stomata at night incorporating CO2 into organic acids. During day, CO2 is released from organic acids and used in C. C
