Document Summary

Use energy from the sun to make their own sugars. Term that refers to processes like photosynthesis and cellular respiration that consist of many linked chemical reactions. The process used by autotrophs to make glucose and other organic molecules. The process used by autotrophs and heterotrophs to break down glucose into atp mitochondria. The organelle where cellular respiration takes place chloroplast. The area in the chloroplast where the light reaction takes place. The liquid portion in the interior of the chloroplast where the calvin cycle (dark reaction) takes place. Accessory pigments that help chloroplasts absorb more light (in addition to the light absorbed by chlorophyll) Another name for the dark reaction - it refers to the fact that carbon is fixed (it is taken from the air and converted into sugars using energy from the sun) This is where all of the carbon that is present in a tree/flower comes from. The source of energy for all life on earth.

The Major Metabolic Processes of Eukaryotic Cells

Plants are classified into a unique Kingdom based on the fact that they are able to make their own food. Some of this food is stored for later use but some of it is used immediately for various metabolic processes that require energy in the form of ATP. Considering this, imagine the inside of a plant cell where both anabolic Photosynthesis and catabolic Aerobic Cellular Respiration are occurring. In order for this plant cell to stay alive it must stay in a constant state of disequilibrium. This requires that the product of one reaction does not accumulate but becomes the reactant in the next step. Fill in the following chart that organizes the major events of these metabolic processes keeping in mind how each event leads into the next.

Metabolic Process	Event	Organelle the Event takes place within	Specific Location within Organelle (Event takes place within)	Input (Reactants)	Output (Products)	Enzyme(s) Involved (may be more than 1!)	*Goal of Event* *[product(s) that get produced & why]*
Photosynthesis	Light Reactions
Photosynthesis	Calvin Cycle
Aerobic Respiration	Glycolysis
	Transition Rx
	Krebâs Cycle
	Electron Transport Chain

List the specific type of phosphorylation responsible for ATP synthesis in each of the following Events:

Light Reactions:		Krebâs Cycle:
Glycolysis:		Electron Transport Chain:
